== Solenoids ==

A solenoid is a electromechanical device that has a movable part that can either

*push or 
*pull

The kinds we consider don't have much power (just a few Newtons usually), but their primary use is to lock/unlock something, like an engine start switch. After the engine is started, that starter switch is supposed to move back to its 'Norm' position. This can be accomplished with an solenoid.

Can usually be driven by one or more of the [[Digital Output Daugterboards]].
