Alat Ukur Kecepatan Putaran Roda (RPM) dengan Menggunakan Sensor TCRT 5000 Berbasis Arduino Nano

Abstract

It discusses a series of methods to measure the rotation speed of the motor , one of which is used in this application , by using slot -type optocoupler and a disc - degree integrated in motor mechanics using arduino nano . Disc degrees who have been given the holes within the exact same will not rotate when the motor rotates , and the holes will make optocoupler produce pulses as a result of its open-closed slot between the LED and phototransistor in the optocoupler.
