You are an excellent instructor by every sense! The verbal is slow and clear. The video sequence is excellent. The test hookup is extremely neat so as your shop. I have learned so much from you in a very short of time. I learn from your instruction and your working habit. You must be made the model of all instructors. Thank you!
If you were to remake this video now, 3 years later, what changes would you make to the line-up? Any newer modules out there worth considering? Thank you so much for all you do to open up the world of hobby electronics to the masses
When messing with my electronics I always stumble into trour channel, and finally get the main idea clarified, with clear pathos on what to do whithin my situation... Thanks for giving this amount of practical detail for these kind of projects!
As a retired mechanical engineer and a great fan of physical computing I can easily understand the theory. But the second part is experience, overview and quick decision-making. This is the point, where people like me need the help of experienced experts like you Bill. It's always a pleasure,to follow your lessons. It can't be done better !!!! Greetings from Germany to Canada.
When you mentioned the 1970s it made me feel much better about the struggle i am having keeping all my components in order. I have only just started, even though I am about the same age as you. Your workshop looks like perfection itself. all the way down to the colour scheme.
Not any single word in your excellent videos is unimportant. So I increase the speed to 1.4, which helps me to see them in a shorter time. Try it by yourself : it's relaxing. You are a great pedagogical teacher. Thanks.
Fantastic. I spent 2 hours this morning searching for power supplies without a clue as to what I needed. And in 30 minutes you explained it to me perfectly. Thanks.
That was a superb way of explaining the power options. The mechanical engineer in me is so happy to learn with you. Please continue to post these type of tutorials. I showed the video structure to my wife who is a teacher. She was impressed by the clarity of the explanantion.
the deeper i go into the rabbit hole of raspberry pi, arduinos, and other microcomputers, the more great content i find from creators like this guy, who is REALLY experienced with circuits. glad i found you. after a few videos, i think youll make my projects easier to understand.
I'm retired now and if there is any thing that i regret for during my career would be not having acess to your very dedicated proffesional informative videos. you have made it so simple and easy. Thank you very much for sharing your knowledge.
I am blown away by your knowledge and ability to relay it to us in a clear and precise manner. I do, however, have one minor complaint. Your shop towels are hung up the wrong way. The free end should be hanging in the front of the roll, not in the rear of the roll. It will keep your dirty/wet hands from accidentally grazing the wall as you go to grab a towel. I'm just busting your chops. It doesn't actually matter to me. Tyvm for your hard work and dedication!
Please make a introduction to electronics series - your videos are so absolutely amazing and I like it so much. I've learned a ton from you. I do feel that I'm missing the basics and would love an introduction series by you.
Excellent presentation! I am an electronics engineer myself, besides having learnt a lot of the finer points from you and being more enlightened, I should thank you a lot, there is hardly any video on simplifying the basics on power supply especially low voltage DC terms. This should encourage more enthusiasts into the hobby and perhaps some might even get into the profession. Great presentation, and thanks for sharing.
BY FAR the best electronics tutorials on the interwebs! I have watched dozens of electronics tutorials but rarely have felt like I had a solid grasp on a concept after; until finding your channel! You answer all the questions I'm unsure about and cover everything I'm interested in! In the last couple days of following your tutorials, I have learned more than in the prior YEAR! Thanks so much for all your hard work! You are super awesome!
I like your style of teaching electronics. Your clarity to explain complex topics that most electronics gurus are struggle to explain it for beginners easy to grasp. Your english is clear and soft enough to follow. The video presentations, editing skills are superb that sequencially arranged for better understanding. You are better than any teachers I know. Thank you for sharing your knowledges. Someday if I confidence enough I will do the same to share what I learn from you to the children far places in my country to have basic knowledges to stimulate their potentials and rise from poverty and stricken situation by using this knowledge to develop a deeper meaning in their life to come out and blend and embrace the technology that help them for advancement in any form of status quo.
Perfect sir, I have finally located a source of info that I can comprehend as a begginer that doesnt plow thru leaving unexplained comments or identifications as wide as the grand canyon making it useless to me. I have already begun ordering and collecting some of these power regs and have ordered a new Ras pie 4 with 4 gig to get into the action with. Why Ive waited until age 61 to start an interest in electronics is unknown but it is what it is. Thank you

I just discovered this fantastic channel. You are filling a void in the TH-cam EE world. Clear, directed and technically correct information. No ranting, bogus "tear downs" of cheap trinkets or racing to the bottom by trying to be some sort electro-comedian. As a career teacher at the post graduate level, now retired and teaching young people as a volunteer, I am worried about the near complete collapse of technically accurate education. Plug and play Arduinos, "robots" and drones have captured young minds but the suppliers of these toys are doing nothing to help new people find a future in the field. They are producing a generation of people who have no understanding beyond what color wire to plug in. I hope you keep up the first class content and resist the TH-cam sponsor and product advertising gravity that has wrecked most channels.

Your understanding of your topics is quite evident and your ability to explain them is remarkable!!!

Thanks so much!!!
This is an excellent comprehensive presentation on what is available nowadays for voltage regulation. I learned my electronics in the 70s when we built voltage regulators from discrete components, transistors, zeners, op amps and even vacuum tubes in some cases. By doing this we learned how they work, but I have an uneasy feeling that modern enthusiasts know little of the internal workings of a chip or module with three or more connections to them and so would just replace it with new. I grant that it makes life easier than poking around diagnosing a faulty component on a circuit board but isn't that the point of learning about electronics. As an extreme example, why use an Arduino to flash a couple of LEDs when the person programming it has never heard of, or may not understand the workings of a simple two transistor astable circuit to do the same job.
As an extreme answer, for the same reason that you built voltage regulators from discrete components and did not have to build the components first in order to use them in your voltage regulator project. That's the whole point of technology.
Hello from California! I'm pretty new to electronics. I can't thank you enough for making these videos. I truly enjoy and learn from them. Have a blessed day!
Your workshop looks so clean and well put together. I don't even have a space for my equipment and its currently laying all over the place mostly on my mom's dining room table.
I don't get how people do it either. Even all neat an freshly swept and organized my lab still looks like chaos XD I also sleep in my lab tho so... lol. Space and organizers makes a huge difference.
@@user-be4yc2vr5c lmao. I sleep in my "lab" too. I'm staying with my mom in a 1 bedroom apt. She has the room and I sleep on the couch.

I'm saving up for a house with a garage though. Then I can finally be at peace. I'll probably still sleep in the garage/ lab anyway, even though I would have a room. I just feel safer around my equipment. Is that strange?
No it's not, especially if you have things in your lab you've made that can keep you safe ;p an goodluck getting a house in this economy buddy! =p The only reason I can even afford a apt. is cause we split rent on a 2 bedroom 3 ways an I sleep/set up in the "living room" 2 of us in STEM fields all 3 in management positions too. lol.

Hi Bill, just came across this video you made 2 years ago, and wanted to let you know it was very informative for someone like me. I like to dabble with low voltage stuff like this for various projects, but I’m not educated on it, and this overview you gave on the subject was excellent. Thank you!
Good instructors teach you what you need to learn. Great instructors teach you things you didn't know you needed. And the best instructors do it quickly. You are a superb instructor. This subject is exactly what I was looking to learn and you taught me more and quickly. Tell yourself that you are making a positive difference in the world, because you are. Thank you.
I really should start searching your channel rather than yt for information. With electronics i often get alot of .. music filled no dialogue videos. (Which i dislike) Eventually find a video you have made. Which ends up teaching me what i want and more.
Thanks. Although I am not planning to use one of those devices in the near future, I am now confident that now I know to chose a suitable device in case the needs comes up. It was again a pleasure to watch the video and to boost my beginner's knowledge a bit.🙂
Thanks for making this video. This gives a lot of clarity to a topic I was having a hard time fully wrapping my head around. As a future topic would you consider explaining when and why you would add certain components into a circuit? For example, at one point in the video you mention that you need electrolytic capacitors for the 78XX voltage regulators, but you say there's no specific size you need and give the size you tend to use. In these cases how do you know that the size doesn't completely matter and what makes you choose the 2.2 micro ferret capacitor? When would the capacitor value matter? Stuff like that. I ask because I feel like I can find lots of explanations on what the components are, but it's a bit harder to find good/clear explanations of when and why to use them. Thanks again. Your videos are a fantastic help in understanding electronics. I appreciate the care and effort you put into them! :)
You can find this specific information at component Datasheets. Look for LM 317 Datasheet. That kind of capacitor do not influence in stability, it only improveh some noise safe, i.e, transient response. You are working with DC power, but you cannot delivery any fluctuations as spikes to microprocessor, it could generate a bad ghost instruction in the processor or even fry it.
The electrolytic caps are used to reduce AC voltage that may pass through the regulator. The exact size isn't too important, as long as it's big enough. So 2.2 microfarads is fine, but sometimes bigger would also work. It would be helpful to you to learn how to read schematic diagrams, and to get the diagrams that show how to use the devices you are using. Without that, you won't really understand what you are doing.
The capacitors are to filter the in and out of the regulator, so you don't have spikes. The capacity depends on how big the spikes are and how many of them you have. The larger the spike, the more farads you'll need.
Best teacher ......i really mean it. Your way of teaching and explaining is too good. You cleared my all doubts about power supplies which i never understood in my college......Thank you
wow! i have been searching this for few days. I want to build a project but different voltage requirements for different things became complex for me, wasnt sure what was the industry standard to providing such voltages in a single project. Thanks a lot sir
These videos are very well done. I would love to see some demonstrations on how you would recommend converting 24VAC to 5 and 3.3 VDC. I've been struggling with coming up with a working solution to monitor voltages on a "dumb" HVAC system with ESP8266 via ESPHome - but my struggles all revolve around my ignorance of voltage conversion!
Hello again. Just found this video and it was a great refresher for me. A lot of stuff that we forget as we move though life. Now that I’m getting back working on the shop bench and working on new projects I’m have a great time of it. With your help it makes it much easier.
Bill with your help here, I made a 9v regulator for a portable WiFi sensor/monitor! I wanted to move off of the solderless breadboard and onto a soldered circuit board. Well, the common USB/barrel jack power supply module that comes with every Arduino kit does NOT fit onto a regular perfboard. So, thanks to this video and the Santos website random nerd tutorials, and about 75 cents in components from Jameco (7805 linear regulator, 100mF and 2.2mF capacitors) I used a 9v battery to supply the ESP32 board and OLED display.
Amazing tutorial, very clear and concise, covering quite a lot of good examples of how to power boards in different ways. Love it and learned something. Really cool stuff. Thanks for sharing that knowledge.
I ran across this video while searching for information on power supplies. Other than computers, I haven't been involved in electronics since the days of discrete semiconductors. Thank you so much for your excellent, clear and helpful knowledge to help me get back into building and experimenting. I really appreciate your sharing of you knowledge and skills with us.
I tell you, Bill has to be the Bob Ross of electronic development. I mean that in a completely positive way. Bill, you are the greatest! Thank you so much for what you are doing for us. Hey, please consider restarting your Patreon and let us throw a few bucks your way. You absolutely deserve the tips! :-)
An excellent introductory summary of how to power your Arduino projects. However, if there are any motors or other inductive loads involved, these can generate massive interference spikes that can cause the Arduino to malfunction or in the worst case scenario, damage it permanently. So information on which regulators provide better protection (line regulation) would be a very useful addition to the video, as would information on grounding techniques and decoupling capacitors.
It is not backwards, it is thoughtfully out of the way from possibly dropping in front of the laptop screen. I like how the end of the sheet is exactly halfway visually down to the outlet. Such symmetry. Ahhh! Ok, Ok I’m being a little facetious but I had to answer the backward forwards challenge. And I was on a roll. Tu-dum-tisch
I love your Channel. You make it so easy to undertand! Your lesson on raises an issue with me: Despite being about different supplies for off-bench project use, the entire demonstration was on-bench. All channels, even Arduino, Adafruit, Raspberry PI, on and on, provide instrution, software, and hardware, but the best of my searches leave me to believe that students of controllers anywhere in the world have projects attached to wires on breadboards strung across bench tops, but nothing assembled into smart deployment-ready packages for the field. If fact, there is a severe paucity of enclosures, with or without precut openings for 16x2 lcd display, or buttons, input or output jacks or holes. Frankly, I'm shocked by the paucity of these materials from the very sources who sell us the nifty controllers and such. I cannot find one source that takes the project developer to permanently wire a controller, a power supply, and fit them and more in an enclosure, ready to use ot show someone else, and use. While I have very good hardware and software skills, I just don't have skill or tools to cut plastic boxes and such to "rerally" make the project. I bet many many people have a project graveyard like me.
"Thank You", thank you very much. Your presentation was REALLY Really really good. I'd like to learn more about DC power supplies. ANY suggestions? Let me know. I look forward to hearing from you 😎
I was looking for information about stepdown voltage and linear regulators. But here we can get a complet course. By the way, english is my 4th language, my listening is very rusty but i'm about of understanding 100%! Thank you for all Sir !
I've been looking for exactly what you describe in the end, for a battery powered device. Thanks for very clear, concise descriptions, definitions, and general operations of the various pieces in each project idea/component. We're about the same age, but I've been out mostly, for a couple decades, not much more than ignition circuits and the like. Getting back into the semiconductors, and grudgingly learning the programing part, slowly. Thanks much.
Great video. I have watched hours upon hours of other peoples videos and would not know anymore when the video ended than what I knew before I watched their video. I completely understand this now. I wish I would have found this video a long time ago. You are great at explaining every detail. Once again, Great Video.
”Thank You", thank you very much ☺️ Your presentation was REALLY Really really good, and it expanded my knowledge on various ways to design DC breadboard power supplies 😎😉😎
Hi I’m Cathal I came across you channel and always had a fascinating interest in electronics and love to learn from someone who knows what the are talking about keep up the fantastic work Cathal
I just discovered your channel through YT's autoplay. Very good channel. I'm also having a browse on your website. Thanks for creating such quality content.
I knew some of this in practice, some of it in theory, the buck/boost new to me and so good looking. Brought to life so now I will be able to use with more confidant and actually know in practice, Thanks.
Great video! I would like to add - if you use buck converters, especially cheap ones from China - be careful, when they break they usually pass input voltage to the output and their input is high obviously. I used them to power my raspberry Pi for 3D printer, which has either 12V or 24V power. So I realized that a quite easy solution for that - put a 5V TVS diode on the output of buck converter (and a serial fuse would help too), then when buck converter fails that diode will prevent high voltage to burn your PI (even if you do not use fuse these TVS diodes are capable of burning trace on PCB, but it would not let high voltage to pass them). For example SA5.0CA one costs $0.40 on Mouser for single piece and can hold 500W on peak!
Thanks for the most excellent quality instruction. I've been out of electronics playground for 20 years and just jumped back in with both feet. Amazing how things have changed, and also remains familiar. This is a great channel to catch up!
I just thought Arduino had built in regulators, I've built a couple of projects using Arduino Nano's and used a 9 volt battery for power. As you can tell no knowledge at all until l saw your video, thanks and keep up the good work. And I'll be taking better care from now on
I am familiar with some of the linear regulators, but I love the buck boost converter, and considering using one in my next Arduino project. As always your presentation is always very clear and comprehensive..thanks
This video has been tremendously helpful to me. I've had a hard time finding a summary as concise and complete to really help me in deciding on how to power my portable projects. I've been building my high powered LED drivers in bizarre configurations because of how many random voltages there are for them!
Thank you very much for this clear and concise videos, I've had more than enough nights trying to address power needs for my small projects and thanks to your information I've purchased the correct equipment and will be undertaking more robotics projects.
Thank you! This is exactly what I was looking for. The presentation was well paced and I understood every word. I now know how to provide appropriate power to the various elements of my project.
Thank you so much for this video. Very clear, very watchable. As a beginner I'm often lost watching TH-cam electronics lessons, but yours was great. Keep them coming!

For example, at one point in the video you mention that you need electrolytic capacitors for the 78XX voltage regulators, but you say there's no specific size you need and give the size you tend to use. In these cases how do you know that the size doesn't completely matter and what makes you choose the 2.2 micro ferret capacitor? When would the capacitor value matter? Stuff like that.
I ask because I feel like I can find lots of explanations on what the components are, but it's a bit harder to find good/clear explanations of when and why to use them.
Thanks again. Your videos are a fantastic help in understanding electronics. I appreciate the care and effort you put into them! :)
Great question.
You can find this specific information at component Datasheets. Look for LM 317 Datasheet. That kind of capacitor do not influence in stability, it only improveh some noise safe, i.e, transient response. You are working with DC power, but you cannot delivery any fluctuations as spikes to microprocessor, it could generate a bad ghost instruction in the processor or even fry it.
He added them for decoupling. www.thebox.myzen.co.uk/Tutorial/De-coupling.html
The electrolytic caps are used to reduce AC voltage that may pass through the regulator. The exact size isn't too important, as long as it's big enough. So 2.2 microfarads is fine, but sometimes bigger would also work.
It would be helpful to you to learn how to read schematic diagrams, and to get the diagrams that show how to use the devices you are using. Without that, you won't really understand what you are doing.
The capacitors are to filter the in and out of the regulator, so you don't have spikes. The capacity depends on how big the spikes are and how many of them you have. The larger the spike, the more farads you'll need.
Best teacher ......i really mean it. Your way of teaching and explaining is too good. You cleared my all doubts about power supplies which i never understood in my college......Thank you
Thank you, Sir, for an extremely useful, informative and well-presented video. I also appreciated the pace of your delivery. Subbed!
wow! i have been searching this for few days. I want to build a project but different voltage requirements for different things became complex for me, wasnt sure what was the industry standard to providing such voltages in a single project. Thanks a lot sir
These videos are very well done. I would love to see some demonstrations on how you would recommend converting 24VAC to 5 and 3.3 VDC. I've been struggling with coming up with a working solution to monitor voltages on a "dumb" HVAC system with ESP8266 via ESPHome - but my struggles all revolve around my ignorance of voltage conversion!
Hello again. Just found this video and it was a great refresher for me. A lot of stuff that we forget as we move though life. Now that I’m getting back working on the shop bench and working on new projects I’m have a great time of it. With your help it makes it much easier.
Outstanding presentation and topic. Great job. Thank you very much.
Bill with your help here, I made a 9v regulator for a portable WiFi sensor/monitor! I wanted to move off of the solderless breadboard and onto a soldered circuit board. Well, the common USB/barrel jack power supply module that comes with every Arduino kit does NOT fit onto a regular perfboard. So, thanks to this video and the Santos website random nerd tutorials, and about 75 cents in components from Jameco (7805 linear regulator, 100mF and 2.2mF capacitors) I used a 9v battery to supply the ESP32 board and OLED display.
Amazing tutorial, very clear and concise, covering quite a lot of good examples of how to power boards in different ways. Love it and learned something. Really cool stuff. Thanks for sharing that knowledge.
I ran across this video while searching for information on power supplies. Other than computers, I haven't been involved in electronics since the days of discrete semiconductors. Thank you so much for your excellent, clear and helpful knowledge to help me get back into building and experimenting. I really appreciate your sharing of you knowledge and skills with us.
I tell you, Bill has to be the Bob Ross of electronic development. I mean that in a completely positive way. Bill, you are the greatest! Thank you so much for what you are doing for us. Hey, please consider restarting your Patreon and let us throw a few bucks your way. You absolutely deserve the tips! :-)
An excellent introductory summary of how to power your Arduino projects. However, if there are any motors or other inductive loads involved, these can generate massive interference spikes that can cause the Arduino to malfunction or in the worst case scenario, damage it permanently. So information on which regulators provide better protection (line regulation) would be a very useful addition to the video, as would information on grounding techniques and decoupling capacitors.
I still can't get over the fact that his paper towel is on the roll backwards...
ha great information. thank you!
It is not backwards, it is thoughtfully out of the way from possibly dropping in front of the laptop screen. I like how the end of the sheet is exactly halfway visually down to the outlet. Such symmetry. Ahhh!
Ok, Ok I’m being a little facetious but I had to answer the backward forwards challenge. And I was on a roll. Tu-dum-tisch
I love your Channel. You make it so easy to undertand! Your lesson on raises an issue with me:
Despite being about different supplies for off-bench project use, the entire demonstration was on-bench. All channels, even Arduino, Adafruit, Raspberry PI, on and on, provide instrution, software, and hardware, but the best of my searches leave me to believe that students of controllers anywhere in the world have projects attached to wires on breadboards strung across bench tops, but nothing assembled into smart deployment-ready packages for the field.
If fact, there is a severe paucity of enclosures, with or without precut openings for 16x2 lcd display, or buttons, input or output jacks or holes. Frankly, I'm shocked by the paucity of these materials from the very sources who sell us the nifty controllers and such. I cannot find one source that takes the project developer to permanently wire a controller, a power supply, and fit them and more in an enclosure, ready to use ot show someone else, and use. While I have very good hardware and software skills, I just don't have skill or tools to cut plastic boxes and such to "rerally" make the project. I bet many many people have a project graveyard like me.
I've been looking for something like this! Thank you so much!
Mister, Long time subscriber and watch a lot of Youtuce videos to learn, you are first-rate, I wish you lived next door!
"Thank You", thank you very much. Your presentation was REALLY Really really good. I'd like to learn more about DC power supplies. ANY suggestions? Let me know. I look forward to hearing from you 😎
Inquire98 , I combined laptop power supplies in a video I made.
I was looking for information about stepdown voltage and linear regulators. But here we can get a complet course.
By the way, english is my 4th language, my listening is very rusty but i'm about of understanding 100%! Thank you for all Sir !
This was absolutely fantastic, I've learned so much! Thank you!
Believe me sir i really love your teaching style and knowledge
Love this video.
Is there a discussion related to HEAT production considerations ..... of power supplies?
100 mf on the output of 3 that reg is to high
If this were a university lecture, it would be one of the best I have seen.....
I love your videos and your website too - thank you.
What a useful summary! Technical enough to be useful but not dumbed-down so much that you zone out.
Thank you so much for this video!
I've been looking for exactly what you describe in the end, for a battery powered device. Thanks for very clear, concise descriptions, definitions, and general operations of the various pieces in each project idea/component. We're about the same age, but I've been out mostly, for a couple decades, not much more than ignition circuits and the like. Getting back into the semiconductors, and grudgingly learning the programing part, slowly. Thanks much.
a really good video.
Please never give up! thanks for that sir :)
Great video. I have watched hours upon hours of other peoples videos and would not know anymore when the video ended than what I knew before I watched their video. I completely understand this now. I wish I would have found this video a long time ago. You are great at explaining every detail. Once again, Great Video.
I'm so happy I've found you and this video in particular. SUB added with thanks!
i am relatively “new” to SMB’s and electronics; 5-10 years or so and i think that coolest thing going right now!
”Thank You", thank you very much ☺️ Your presentation was REALLY Really really good, and it expanded my knowledge on various ways to design DC breadboard power supplies 😎😉😎
Man this guy gives me an idea of what thing to use to power my projects
You are a great help! thanks a lot. Keep up the good work
As a nascent to all things electronic - thanks for this. Subscribed.
Great topic.
Hi I’m Cathal I came across you channel and always had a fascinating interest in electronics and love to learn from someone who knows what the are talking about keep up the fantastic work Cathal
at 1:46 I felt like he was talking directly to me...
I just discovered your channel through YT's autoplay. Very good channel. I'm also having a browse on your website. Thanks for creating such quality content.
Very useful thank you.
Sir. You have no idea how helpfull these videos are
You must be good teacher. Now I can understand the difference between the power supplies. Thank you.
I knew some of this in practice, some of it in theory, the buck/boost new to me and so good looking. Brought to life so now I will be able to use with more confidant and actually know in practice, Thanks.
Nice! The MT3608 is _exactly_ what I needed for my project! So glad I took the time to watch this video! Saved me a lot of work. :)
Great video! I would like to add - if you use buck converters, especially cheap ones from China - be careful, when they break they usually pass input voltage to the output and their input is high obviously. I used them to power my raspberry Pi for 3D printer, which has either 12V or 24V power. So I realized that a quite easy solution for that - put a 5V TVS diode on the output of buck converter (and a serial fuse would help too), then when buck converter fails that diode will prevent high voltage to burn your PI (even if you do not use fuse these TVS diodes are capable of burning trace on PCB, but it would not let high voltage to pass them). For example SA5.0CA one costs $0.40 on Mouser for single piece and can hold 500W on peak!
Thanks for the most excellent quality instruction. I've been out of electronics playground for 20 years and just jumped back in with both feet. Amazing how things have changed, and also remains familiar. This is a great channel to catch up!
I just thought Arduino had built in regulators, I've built a couple of projects using Arduino Nano's and used a 9 volt battery for power. As you can tell no knowledge at all until l saw your video, thanks and keep up the good work. And I'll be taking better care from now on
Good show my friend. You almost seem to enjoy giving a tutorial better than we enjoy watching. Keep up the great work.
I am familiar with some of the linear regulators, but I love the buck boost converter, and considering using one in my next Arduino project. As always your presentation is always very clear and comprehensive..thanks
This video has been tremendously helpful to me. I've had a hard time finding a summary as concise and complete to really help me in deciding on how to power my portable projects. I've been building my high powered LED drivers in bizarre configurations because of how many random voltages there are for them!
Great , good introduction , and Your pronunciation is very clear. Keep on the track
I'm a big fan of your works 😍
Electrical Engineering student from Philippines
Amazing, i wish you were my university teacher.
Just recently got into Arduino and I love your channel. Thanks so much for making these videos.
I know very little about electronics, and this video has helped me a whole lot, so thanks!
Thank you very much for this clear and concise videos, I've had more than enough nights trying to address power needs for my small projects and thanks to your information I've purchased the correct equipment and will be undertaking more robotics projects.
I love those little boost/buck convertors. So handy on the led lights I make.
Thank you! This is exactly what I was looking for. The presentation was well paced and I understood every word. I now know how to provide appropriate power to the various elements of my project.
Great video! Very useful to see actual modules for generating commonly required voltages.
I ALWAYS enjoy your comprehensive, detailed, and above all, very well-explained videos! Great work!
Thank you so much for this video. Very clear, very watchable. As a beginner I'm often lost watching TH-cam electronics lessons, but yours was great. Keep them coming!
Perfect demonstration, leading to a "reference" video .... THANKS
amazing. your delivery and communication skills are top notch! thanks again sir.
