Connecting a coil, relay, pneumatic or hydraulic valve or solenoid
by BARRAGAN <http://barraganstudio.com>

This schematics shows how to connect a coli, relay, pneumatic or hydraulic valve or solenoid to a Wiring binary or PWM pin. The MOSFET switch allows to connect different voltage devices to the Wiring I/O board that can't be directy connected to it. Verify that the voltage applied to the coil is in the range supported by it.
