DIY | Ambilight using Arduino Nano
pretty cool. good job man.
I tried it and it worked perfectly. my mosfet is also strangely cold, works a bit over ambient temps(with a heat sink).I've used an arduino to provide musical tones to Q2(replaced with tip41c).
ٍEasy way to make it musical, same schematic but instead of using a triple 5 modulator, you can put any musical source, speakers output with an amplifier would work fine.I used an Arduino and loaded up some RTTL musical tones on it, then wired the output pin to the transistor (Q2). it worked like a charm.
