Electronics

For the electronics of the mechanism we designed a PCB that controls a servomotor that activates the mechanism to unlock the locker. The PCB includes a voltage regulator 7806, connections to the raspberry, a mosfet to give voltage to the servomotor, a connection for the servomotor and a port to give 12V to the board.

Mechanism

We designed a mechanism that we printed in 3D with PLA filament that goes inside the locker which will hold the electronics and the servomotor that will lock and unlock the locker.
