In this video we look at how to go from a schematic circuit diagram to puuting the components on the breadboard and making the connections.
This circuit is an astable multivibrator, or an oscillator. The 555 timer drives pin 3, the output, high, then low, over and over. Where you put the components is up to you, but try to arrainge them logically. When it comes to making the connections, look for where things converge. For instance, look for all the connections that go to VCC, these can all me wired into one row, same for ground. Keep in mind that when using a breadboard, the vertical columns are connected under the plastic by a metal rail, so everything plugged into one column is connected together in parralell.

You are a great tutor. I never get tired of watching your videos. Your passion is inspiring to beginners like me.
This helped me visualize and conceptualize this so well, as I am still a beginner. Thank you, Paul.
Great video. I like the way you go over things nice and slow. It really helps newbie hobbyists like myself.
Thanks.
Another helpful hint, use a highlighter and mark each connection that is completed on the schematic.
Thanks Paul, have a restful evening.
I've been trying to get an understanding of how and why different 555 modes work. I put the cart before the horse a bit and didn't quite grasp how to go from circuit diagram to breadboard (I'd been setting up circuits by looking at assembled examples). I searched Google and you have a video on the specific 2 things I'm interested in. I've already been enjoying your videos for weeks. I know this video is 3 years old, but I just wanted to say you're doing a great job and I appreciate it.
This is one of the best channels out there for the up and coming electronic gurus, even though you never did put RDS on your fm radio back in 2017. Great info!
:)
Short. Simple. Brilliant. As ever.
I enjoy watching your videos, just when I think I have mastered the breadboard, I learned something new. Installing the resistors, I never thought of placing the resistors on the breadboard like you showed. Great learning video even if you are a pro at it... Thanks kindly for your knowledge...
Nice and neat. A lot of my projects get away from me. I have to reverse engineer the bread board to see what I've done. LOL.
I think you should do a video on this where you make 2 of the same, but one with long leads and one with short leads, and hook them up to scopes to show the difference. Just a thought.
Great video Paul, I make my own pcbs so... but a brush up never hurt, I gotta watch all your videos. I hope you get to 100k, so close!
Awesome video mate, I've been playing with electronics (hobbywise) for 25+ years. Best description I've seen. The BBS's weren't quite the same back then as utube. Subbed!
Awesome lesson again Paul. Thanks 👌
You're on! Good luck on reaching your goal!!
Still doing a great job paul stay safe and big thanks
Thanks. Very clearly stated rationale and probably makes the next step, breadboard to PCB, straight-forward, too. Kennedy
Great little circuit!
Thanks from France !
Coooool and Simple.. Great job Sir..... I love your apprauch....🇧🇭 Stay safe... Have a great day.... ✌️
Clever as always. Thanks. Can you do something with optocouplers?
Fantastic video Paul, I remember way back when I would struggle with translating a schematic to a breadboard. I’m glad you can show new makers that it’s not as hard as they think it is.
I'm subscribed! 😁 Thanks for the video!
I found this presentation to be very useful to beginners. Just for a suggestion, I would have liked to see the capacitor swapped out for a different value.
Many thanks,
Arthur
Thank you, very helpful.
Great. Thanks 🤙
I did subscribed. great video
outstanding thank you
Can you please do a video on the joule thief and its variants? Great video by the way.
Thank you! !
great channel
pretty cool video :)
Thank you
Thanks.......you are great
Nice Video Paul;)
THANK YOU!!!!!
The UT61e+ is out! Time to buy a new meter.
Hi. Wondering why you routed wire over the top of the IC from pin 4 to 8 rather than just connect pin 4 to VCC directly below? Isn’t that neater?
nice video
I get what you are saying in the video, but what confuses me is how you connect things like this with other modules to build complete bigger modules. I'm still learning, trying to build a mini analog synth or noise maker. For musical fun.
Cool..
Upsets me to no end when a 555 is employed in a schematic, they NEVER represent the IC Pins as in real life. The drawing always simplifies the routing.
Mate, i hope u get these 100k subs soon!
Paul, you didn't say what value the resistors are
👍
555's can handle 15 volts with ease.
Please make R1 much larger if you want to see the blink...
Wow
1:34... The spec sheet of the LM555 states a usable supply voltage of 4.5VDC to 16VDC.
That's true, but it does begin to heat up above about 7.5VDC. So I try to keep it below that.
@@learnelectronics What are the values of the 3 resistors that you used in the tutorial ?
I am surprised that the breadboard puts the two power rails on opposite sides of the board. It may reflect the geometry of the circuit diagram, but from the electronic point of view, it is better to keep the supply rail as close together as possible.
There are two power rails on each side of the board, it is better to use each pair as the +ve, and -ve.
To keep the supply inductance as small as possible, it is a good idea to connect the rails in parallel at one end of the board.
Then fit a large value smoothing cap on each pair, at the supply end of the board. It is a pain to connect the IC supply pins from either the top or bottom pair of rails, but it does avoid creating a big loop out of the supply connections.
This is also a common mistake made by beginners when they first use Strip board (also known as Vero board). They lay the circuit out as it is shown in the circuit diagram, placing the power rails on opposite sides of the board, effectively running the power tracks as far apart as possible. This also creates a big inductive loop out of the power rails, this can make the supply noisy, with a poor transient performance and make it susceptible to noise pick-up. It also make digital circuits radiate. It is possible for inputs such as resets trigger on supply pick up noise. In general, big circuit loops are a bad thing and should be avoided, both in the supply rails and In the signal paths.
One of the annoying features of these plug in breadboards, is that the supply rails that run down each side of the breadboard are not continuous, they are broken into sections, requiring links to be added to make them continuous. This used up valuable connection sockets. There is almost never sufficient free sockets on these power rails, to connect all the pins that need to be grounded on an IC, things like unused inputs. Similarly there is always a shortage of near by pull-ups to the positive supply rail, so it is always a good idea to Daisy Chain such connection around the IC using link wires, as shown in this video. It's unnecessary and undesirable to connect every zero volt pin of an IC back to the negative (or zero volt) rail.
The above principles become very important if the breadboard is being used for testing an analogue circuit, where loops,earth loops and EMI pickup is important to avoid.
Now next video can be breadboard to PCB :)
If it's "much simpler", as you say, then why didn't you draw it that way? I think it's "much simpler" for you to connect with minimum wiring, but certainly not so from an understanding it point of view. I'd like to see a "neat" version with an explanation of why it would not be a good solution as you state.
