 ### Solenoids
 
-First you will need a build a circuit to drive the solenoid through a mosfet as most MCU will not be able to provide the current needed to drive the coil in the solenoid.
+The solenoid code supports relay switches, and similar hardware, as well as solenoids.

+For relay switches, the hardware may already contain all of that ciruitry, and just require VCC, GND and a data pin.

 * If solenoid buzz is off, then dwell time is how long the "plunger" stays activated. The dwell time changes how the solenoid sounds.
 * If solenoid buzz is on, then dwell time sets the length of the buzz, while `SOLENOID_BUZZ_ACTUATED` and `SOLENOID_BUZZ_NONACTUATED` set the (non-)actuation times withing the buzz period.
