Hi again all!

Say i have a really simple circuit.

Just a 9v battery, to a 9v motor.

And i want to use a pic circuit to control this circuit how would i do it?




So my simple pic circuit running allowing the current to pass through the higher voltage circuit only when the leg is "high"
(sorry about the crap diagram, but hopefully it shows 2 seperate circuits, with the 5v one controlling the 9v one)


Many thanks.
