This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much in ...

This is a basic Tachometer, it uses a Hall effect sensor to detect a magnet on the shaft of the device you are measuring the speed of. Output is to a LCD screen in RPM. The screen brightness can be ...

The project utilizes an IR (Infrared) sensor to detect the rotational motion and an Arduino Nano to process the sensor data and calculate the RPM. Digital tachometers are widely used in various ...
