In this paper, the authors present the development of a microprocessor based automatic gate. The inconvenience encountered in gate operations has called for an immense search for solutions. The microprocessor based automatic gate offers everything necessary to put an end to these inconveniences as it incorporates an intelligent device (microprocessor). Specifically, the system described in this paper monitors two gates, the entrance and exit. The automatic gate senses any vehicle approaching it. It automatically opens, waits for a specified time, and closes after the time has elapsed. As soon as the gate closes, the system counts, registers, and displays the number of vehicles.
