dissecting an IR remote-controlled color change LED Answered
Okay, I bought one of those remote-controlled color changing LED candle things. I want to get its guts as small as possible. My knowledge level is basically "LED + battery = glowy" so I need some help figuring it out. I've attached a pictured. I tested and it will work with 3 volts. I get that obviously I need the RGB LED, the IR receiver, and the control chip thingy... but what is everything else? I'm figuring resistors and capacitor/transistor, but I don't understand these and why I need them, and why so many?! Any chance some of them are just for lowering the voltage down to 3, and now that I'm using only 3 they are no longer needed?
