Great instructions. Completed on my first go no issues. ( i have a few hundred extra bits of each part though now lol) thanks a bunch!
Hello, im using a home made arduino to power an led matrix of about 120 leds. Anyways i would like to have the arduino shut off in light, on in night. I would like to set this up inbetween the 5 volt regulator and the atmega chip. Any idea what reaistance i should use so my atmega still works fine at night? ( its a 24x6 matrix for my 5 year old ). Thanks!
