Looks like a fun project. Thanks for the upload.
If I wanted to make this circuit using a 3V source and more LEDs in the circuit, would I need to change the resistors??
it is not possible (timer 555 need minimum 4,5 v supply voltage), but you can use dc-dc step up converter and lower 180 ohm resistor if you use more leds, you need replace bc547 with more powerful transistor ...
You can but you have to use a CMOS timer, like TLC555 or LM555
with 5V I just can't get it to breath. I did change some of the values, importantly the resistor in series with the LEDs, but also the other resistor and capacitor. It does rise slowly, and then just stays on. I can imagine the voltage drop of the 555 is too large to operate this circuit with 5V. Or perhaps the specs of the transistor are critical, because I did use another npn
Same here, the thing that worked out for me is havin a bigger load on the emitter side. Why that? i honestly have no clue.
Like if i try to fade two red LEDs at 2.2 forward voltage drop, i cant, but two green LEDs at 3.1fv im able to do this affect.
What is the output voltage? I want do something like this with a 12 Volt LED strip in my car. What is the configuration for 12v in and 12v out?
very easy to follow, thank you ❤️
Great work brother
Good goob thanks
Goob
If I want a 5V source, since it is minimum specs, will this work or do I need to use different resistors?
Amazing
is that an NPN or a PNP transistor (why not post a schematic at the end of your videos?)
This mode is really safe for people who has disabilities though. I understand that there is a warning label but wait there is a mode selection.

very cool
Would it work with a 5.5v solar cell?
Shematics plz???
Excellent. What if I want to run 20 LED's and have the breathing speed up just a tad? Do you answer any of your comments?
For the speed you can change the value of the capacitor. And you can do 20 leds but then it's best to provide each led with its own resistor. I hope what I'm telling is right but that's just what I think.
I think with 20 Leds the circuit is the same (because parallel LEDs have the same voltage drop as just one LED) and the timing is likely controlled by the value of the Capacitor. So smaller capacitor is faster frequency. Is my guess. but I am going to indeed try what you propose. Note that different color leds need different value of resistor on pin 1. this is easy to google, you'll find it.
Will this work for any amount of leds?
What should i change when i use 5volt batteries?
My question too. 😊
Sir , what volt of 470uf used?
10V or more
Ware is led + comming?
Can this circuit support usb?
hello.is it possible with the current setup to run at 12volts?
Offcourse
@@estechknowledge ty verry much
@@dreadpointgr96 no ty
I hope you put the equipment and the instrument name you use. Its hard to identify what specific instruments/equipment to use for that project. Just recommendeding.
Peace✌️
How many leds can be powered with this circuit?
Less than 10 LED
इसमे rgb led use कर सकते हैं क्या
5v pe chalega kya?
Can any other color led be used in this circuit?
Yep, just use proper resistor
Triangle wave
Does this circuit work from 5V USB?
i cant get it to run
can i use 12v voltage in ?
Give it a shot, maybe put a bigger resistor
470uf you used? 16v? 25v 35v?
Use more than 16V
If i used 14 leds in this circuit, can this circuit handle it? Because i tried it before and not work, 14 leds 9v, please your advise my friend
@@ivansutanto89 green led is 2.2-3.5V, so with 9V supply you can use only 3 leds.
