I have a Microvision laser pico projector which runs off 5v 1a and I'd like to be able to have an auto-off timer for it controlled by a Picaxe.
My initial thought would be to use an n-channel MOSFET to connect/disconnect the ground line of the power, which would be a quick & easy solution, but this could cause problems because the projector also has a ground line from the VGA connection.
How can I easily switch the +5v line on/off from a Picaxe?
