I have a 16 foot RGB LED strip. It runs at 12 volts at 14.4 w/m. I think I understand it needs 144watt power supply at 12v to light them (coming from China, so don't have them in hand yet). My question is, I'd like to hang these under my RV and have an Arduino do a slow fade through the color spectr…

Want to control 12v LED strip via arduino PWM pin
