I have a LEDStrip that I am fading through the different colors, however when I was using just the 12V 5A into the barrel jack, the arduino got uncomfortably hot but lights worked as intended.
SO, I got a seperate supply to power the Arduino as you can see here, but now the lights do not fade...
They only stay white(bright too). The code is uploaded onto the arduino too.
When I changed it to this, it works fine agian... Why is this? I dont want to put 12 Volts into the Vin because of the fear it might make the voltage regulator hot.
