Abstract
A tachometer is a device that measures the rotation speed of a shaft or disk, as in a motor of other machine. In automotive use, it is used as a gauge showing the speed (RPM) of the engine shaft that is driving the transmission, usually in thousands of rotations per minute. What makes this device special is that it can very accurately measure the rotational speed of a shaft without even touching it. This is very interesting when making direct contact with the rotating shaft is not an option or will reduce the velocity of the shaft, giving faulty readings. This device is built on a microcontroller, an alpha-numeric LCD module, a battery and a proximity sensor or an infrared to detect the rotation of the shaft whose speed is being measured. If we were using proximity sensor, the counted pulses will detect any reflective element passing in front of it, and thus, will give an output pulse for each and every rotation of the shaft. But if we were using infrared, we will put the infrared on both shaft and the tachometer. Those pulses which we get from every rotation of the shaft will be fed to the microcontroller and counted
