The Final Year ECE project deals with the design and development of microcontroller based elevator control system with stepper motor, display and voice announcement.

The elevator system can move up, down. It also indicates floor position on seven segment display. The user can control the elevator with the switches provided. The elevator control system is designed with stepper motor mechanism. The stpper motor is driven through L293d motor driver circuit.

The elevator system is designed with five floors with equal heights. The APR9600 Voice Chip Module is used to record and playback voice messages upto 60 sec duration.
