APLIKASI COUNTER DENGAN MIKROKONTROLLER UNTUK MENGHITUNG PENONTON DI PINTU MASUK STADION DENGAN SENSOR PING DAN LED

Abstract

Total Attendance Countdown is an appliance which is controlled using a sensor ping. This tool can work if the sensor detects an object ping in front of him with a distance of 3 cm to 3 m.
