Hello again!
Even though I haven't quite figured out my last LED thingy I thought I would ask this. I am trying to get an RGB LED to randomly fade in and out of all colors with minimum board real estate available.
I have seen this circuit by Audioguru and was wondering first if someone could walk me through it's operation. I have a basic understanding of feedback and opamps but I would leave it at basic.
Secondly could you use comparators instead of opamps? If so I have a LM339.
Thanks!
I was thinking there is another easy way to fade the LED. using a capacitor in parallel with the LED but I have noticed it only fades one way and either turns on or off abruptly. How to make it fade in AND out like in this video. I thought I saw the connections correctly but My circuit didn't work like his.
