How to wire ULN2803 | darlington pair ULN2803A wiring
มุมมอง 77414 วันที่ผ่านมา
The darlington pair family of ULN like the ULN2801A ULN2802A ULN2803A and ULN2804A are pretty common but a bit different in wiring. While it is in itself simple, it's a bit counterintuitive how to wire the ULN2803A. In case you wanna connect loads to your GPIO pis of your Raspberry Pi, ESP32 or Arduino, a darlington pair is a good choice to protect your GPIOs! So check out this video where we c...

Direct exposer with a laser? | laser circuit boards
มุมมอง 4.3Kหลายเดือนก่อน
PCBs are normally exposed and afterwards etched, in some cases printed, but direct laser exposer offers an alternative way. Requiring an UV laser, you can expose the circuit directly. Using a CO2 laser instead of UV laser, we had to burn the coating away and go for etching directly.

KINDLY ASKING Here Trying to run a PI NODE on my windows 11 pc but still failing - this is the error i keep getting whenever i open the Docker-Desktop App 👇 *❌ Something Went Wrong* Updating wsl.exe failed---web-download not supported 👆 *I kindly welcome any help* *Thanks*
Normally the Pi specific nodes don’t run on any other platform. The GPIO node for example would try to call a pin which is simply not there. Why do you wanna run Pi nodes on windows? For convenience of programming or are you planning to connect a Pi somehow with your PC?

How did you manage to get 40-50 degrees C with that aquarium heater? Those heaters have a thermostat that allows 32C. Have you opened the top of the heater and tamper with it?
great video! i wish it were easier to find content like this
I wish too 😅 So in case you know someone at TH-cam, make sure to tell them to boost my channel 😅😁 Thanks for your feedback and your comment! Likes, comments and sharing content helps with the algorithm a lot! Also let me know if there are any topics your interested in!
Just finished my chapter about on Ram - I hate reading- you just brought it all together. Thanks so much for this valuable piece of information. NuSbr🤘🏾
Thank you very much for your feedback! I prefer videos for learning too, trying to cover all the topics I always missed on TH-cam, all in one format. Was always getting annoyed watching a different channel for every topic… Good luck with your studies!
Danke für die guten Videos. Ich war mal ein Student von Ihnen wollte fragen wie es Ihnen geht!
I am getting polling error..what to do ??...please help
API key is correct for sure?
@@blueprintiot Yes its correct.
Очень подробно. Мне помогло. Я подписался. Пришло время для продолжения ))).
Thank you, keep going, learning new things is always motivating and worth it!
Bro, I don't think you should be commenting on electronics til you learn how to use the volume control when recording a video.
"Qwiic" is just "Quick", the same pronunciation
Clearly explained, short and sweet. Thanks!

Can you do biology?
how long is the cable?
Hi, thanks for you good question! I just measured it, including the connectors it's almost exactly 2m Hope this helps you, otherwise feel free to post further questions! All the best
Could you simply explain why there is 5 and 3 volts to begin with.. Why everything is not on a single voltage only
Hi @Rafael, thanks for your question! As many things in electronics it comes down to industry standards. As mentioned 5V is very common since it’s the USB voltage. So for many DC DC converters, power supplies and so on are available, mass produced and so for cheap. 3,3V in the meantime is exactly 2/3 of 5V, so a natural step from 5V, easy to achieve with a 10k / 20k Ohm voltage divider. In general highly integrated chips like microcontrollers, CPUs and so on are working with even lower voltages (to high voltages increase the risk of arcs if you put circuits closer together to miniature). So it’s easier, so to speak more efficient and cheaper, to step down from 3,3V to let’s say 1,2V than to step down from 5V to 3,3V. Those are all technical reasons burnout really comes down to manufacturers settled on certain voltages. Same way as you have different bus communication protocols.
You can't use clock speed to determine performance, you've not been able to for decades.
Amazing!
Thank you!
Man, you are a lifesaver, why don't u have any views, wtf?
I’m asking this myself every day ;D I was trying to find out how to record the screen for some of my node red videos and wasn’t able to find a proper explanations, so decided to make this video, so others can use it…. Feel free to send it to any other people who might benefit from it!
Good!
Thank you!
Are you working with Thingspeak on a project?
@@blueprintiot yes
If I'm working on a smart greenhouse, I send the data to a web page.
the ESP8266 costs 4 Euros and the ESP32-C3 costs only 3 Euros. In many cases the C3 replaces the older ESP8266. The ESP8266 also has more restrictions on which pins must be high or low when booting. The ESP8266 can only be woken up from sleep mode by a reset. I wouldn't be surprised if the ESP8266 is discontinued soon.
Interesting opinion! I was using the 8266 in many cases, simply because the performance was sufficient and so for I had no reason to spend / waste the extra performance of the 32. Anyways since the price gap is becoming smaller I would also opt for the 32 more often, simply for the backup performance.
What I’m missing is a board with even less performance and even smaller price. Use case: one sensor, to be wireless. Any recommendations? One GPIO would be enough + wifi / BLE
@@blueprintiotthe ESP01 HAS WIFI and twj gpio pins.. very small and very cheap. But no Bluetooth
@@stedunn563 that's a really good input! Actually used them before, but only to make the Arduino Uno Wifi capable :D Weill definitely try whats possible! Should I document and put a video together about the testing and what's possible?
Great summary and thanks to the informative comments too!
Thank you and thanks to everyone commenting! Great to experience different perspectives from all around the world!
Great video
Thank you!
Although a cheap redmi phone has better performance than this chip.
Redmi phone also has multiple separate computers in it. Even sim card has a faster processor than a c64 to run its java applets.
One thing it doesn't have is many ports and it can't run a different OS.
@@dbsirius It can run different OS no problem and with USC-C dock you can have as many ports as you need.
Good summary but you should have included clock frequency, number of cores and the voltage. You said they are all 3.3V but the Pico has an on board boost/buck regulator so it can be used from 1.8 to 5.5 volts. No criticism of your video but I think those parameters are important in any selection comparison.
we are going to buind a 6 dof robot arm which can be controlled wifi or Bluetooth. I was planning buying the giga. The money is not my money and i dont mind if it is expensive. Does anyone recomend anything else? I have no other experince on board other that using arduino
what about comparing the arduino mega and the Chinese clone ?
Sure, do you have any specific types in mind?
great summary ;-)
Thank you for your feedback!
Thank you for making this video
Thank you for your feedback! If you’re I retested in other topics / projects, let me know and I’ll put it on the list!
I'll wait patiently for the clones to start to show up on Aliexpress for less than 4 euros.
It's pronounced "quick"
I'm going to get the Giga when it's back in stock. My project is a waste oil heater. Needs over 40 pins. Four thermometers, status lamps, 2x LCD displays, rotary encoders, solid state relays, 3-4 LED digit displays, 2 hall effect sensors for blower RPM, and it's preferable to have onboard wifi. I agree that it's overpriced, but I think it's the best board for my needs.
The thumbnail looks like the board is giving you the finger
😂😂😂 True, haven’t seen it before, but TH-cam approved it anyway 😅
It's funny their WiFi chip is basically as powerful or more powerful than the main chip. Biggest thing "striking it" from this project in particular is it only being 3.3v capable However I've always been weirded out by the pin form factor. Its nice and big for first impressions but quickly becomes unwieldy for integrating into a project Comments are never put into your actual executable code as the program size Would love to see one or two versions of these in the nano format.
Interesting machine
Absolutely! Total change for prototyping and customising!
Uno is good for education or maybe one off projects, but that's about it... 18-25 EUR / borard is far too high for making products in volume and still be competitive on the market. I personally never cared about wi-fi on every microcontroller board, or even having USB... I care about low price, and small size, but then they killed the pro-mini, and came up with some overly expensive shit... Good thing is I can still find pro-mini knockoffs at least. The thing is If I need wi-fi, I prefer ESP12 modules, if I need lots of I/Os, picos are cheaper, If I need cheap controllers, I use bare chips(atmega328p, attiny44, atiny85, etc.) and now I'm looking into to STM32s cause I've got a few low power projects...
Well done and very helpful! Vielen Dank!
You’re welcome! Let me know if you have any topics you would see a video about!
Imo an external ADC might be a good choice. I'm working on my solar tracker and bought some solar sensor to track the sun with an arduino uno r4. But i just stumbled over esp now and four small pv panel in combination with esp32 might be enough.
Thx for insight! Do you have a video or website about your project?
@@blueprintiot No but I am on it. I keep you here updated. What about your project?
Nice! Helps me a lot on the purchase decision
100% recommended
I think it would be nice to have a Minima with LED-matrix, but I gues I'll just get the WiFi version.
Eventhough the wifi version is a bit bulky, I think you just unlock a lot more use cases…
And if you really want to habe a LeD matrix on the Minima you can always get a shield or external one …
@@blueprintiot looking at the schematic for both versions, it seems like the LED matrix make use of NC pins from Minima. Then there are a few NC pins on the ESP. I think it would be interesting to see an Arduino R4 Mega, making more GPIO available.
@@blueprintiot I mostly agree with your point, that you get a lot extra with the WiFi model. I'm not surprised if there will be clones with either WiFi or LED matrix
You should have shown what SD card & SD card reader you used to get the OS onto the flash drive. I don't know why people keep skipping over this step.
That’s really up to your setup. Personally I’m on a MacBook Pro 14“ M1, so I just use the adapter from micro SD to SD that comes with basically every micro SD card you buy. But used a micro SD - USB A adapter in the past…
But please check this more recent video, covering only Balkens etcher. Flash Raspberry Pi OS using Balena etcher - full process th-cam.com/video/DXcQNv-GsY4/w-d-xo.html
Anyway thanks for the feedback! Actually a video about micro SD cards is on the way. There are major differences to speed, cost and most important durability. So stay tuned for this more detailed insight in micro SD cards!
What i would really like is a R4 Minima, but in the formfactor of the Nano or Micro.
Consider an ESP, even comes with wifi… Or is there a specific reason you’re looking for an Arduino product? Simple wifi capable microcontrollers - Arduino Nano IoT vs ESP32 vs ESP8266 vs Raspberry Pi Pico W th-cam.com/video/psDdNgPPSoU/w-d-xo.html
@@blueprintiot I want a 5V based MCU. Almost all the capable MCU now are 3.3 V. I use the boards in a 5V environment. Of course you can do levelshifting etc. But would be nice to avoid it.
Can someone explain what the use case is for an onboard LED matrix? For that matter, what is the use case for any Arduino when superior alternatives, often at lower cost, are available? No matter. If Arduinos prevent more buyers of Raspberry Pi, then go for it.
I think the LED matrix can come in handy for instant visual feedback during development…anyway we have to take into account the education use cases where an out of the box LED matrix is useful for beginners. For other usecases I would also prefer ESP boards, maybe build quality is a pro for arduino…anyway, super interested in all the arduino use cases some of you may have where other boards are no alternative….or the reasons why you opted for arduino…?
@@blueprintiot Thanks for the input, Blue. I'd also be interested in what your viewers are doing with it. As well, I'd be very interested in what the Arduino people thought justified the expense in real estate, matrix components, and pick-and-place assembly time. The only 'visualization' I've seen so far is a crudely rendered Christmas tree and a heart-shape for whatever reason. I mean, what alternative functionality did they reject for that real estate?
