Lock Peripherals used in blueprints

Smart devices might need keyless locking functionality, e.g., a vending machine, a post box, or a smart door lock. Here are a few that are used in |main_project_name| Blueprints.

Solenoids

Solenoids are electromagnets. When the coil is energized, it pulls the lock cylinder to unlock. In the non-energized (unpowered) state, the lock is engaged.

Solenoids with key and button backup

For applications where you want to be able to disengage the lock in the absense of electricity.
