Relay Outs from Ardino Board(s)


I'm interested in determining how to get relay outs from an ardino board. That, OR.. Going from one of the possible/common digital output types and setting up the circuit that would equivalently allow me to use this as a relay out.


What do you mean by "relay outs"? Do you want to control a relay with the Arduino? If so, that is pretty common and Google would yield plenty of results on how to do this.

This may help you:

Look at

A $3.99USD relay board (2 relays).
Tell us more what you want. Do you want to control a LED, or the city electric grid? LOL
Do you have an arduino already?
