Me and 2 friends created this elevator for the grandmother of one of my friends.
George knows very well the metal construction and it is his job.
Bagios is electrician and i am electronic engineer. And voila!
The main board contains the necessary i/o optoisolation and the arduino mini pcb.
3 floors-3 buttons on each floor-3 sensors on each floor-3 buttons and an alarm inside the elevator and 2 terminal safety switches are included for the main installation.
The motor is 230vac and the main board drives it via 2 relay outside the main board to avoid noises from contact relays.But before the current reach the motor it passes through 2 terminal switches in the upper and lower construction.
