I guess I'll try a 5v relay. And to be sure, the Ardunio can trigger the relay (Using Write HIGH and LOW Commands) to activate the Nano correct? So I can have the Nano activated or deactivated anytime via the Arduino Nano, correct.
My end goal here is to make my own A.I system via the Arduino MOVI shield, and in order to reduce the length of code on the MOVI shield (that is attached to an Arduino Uno or Mega) I would like to have it activate separate Ardunio systems (mostly Nano's that each control Lights, or mini Robot arms) so it's easier for the MOVI shield to handle.
If relays are the best way to go then I will invest relays into my project to activate and deactivate the Arduino Nano systems via the Arduino Uno/Mega and MOVI Shield.
Thanks in advance.
