Arduino Tachometer (RPM Meter) With IR Sensor Module

Includes *project file *one time code and project explanation A tachometer is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on Analogue dial, or on digital display. In this project, tachometer is made using an IR Sensor module as unit for measuring the number of rotations.
