esp-garage-hardware

NOTE: The hardware is in its early development. This is meant to replace your garage opener, if you'd like to use this with your existing garage door opener only slight modifications are needed. As of now relays control the motor, in the future there will be a motor driver circuit integrated on the PCB.
