by flashpoint on Wed Feb 06, 2013 1:39 pm

I have is on and off switch on breadboard connecting Arduino.
But I can't get the thing to work with raspberry pi. My Raspberry Pi could not boot OS on TV screen but it have power led on. It's all black. Nothing.
My arduino wire is connected to 5v pin to 5v to raspberry pi.

Pin 12 is turn on and turn off the adruino. But I don't know how to make Arduino power on/off communicating raspberry pi. I don't know where to connect pin 13.

Switch press -- The wire pin 13 is
digitalWrite(13, HIGH);

Are you trying to power the raspberry pi from an arduino digital IO pin?
