How to use this Project

This project can typically used as a door opener for a garage.

a) The ESP can identify the state of the door normally by a reed contactor, if the door is closed the button gets green to signalize Door is closed.

b) If you press the button the relais closes about 800 ms and the motor starts to move. If the Door leaves the the reed contactor the button gets red to signalize a not closed door.

It is the same procedure than you push the button in your garage.
