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 ...
Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...
Hello everyone! Today I’m going to discuss a cheap type of useful digital rotation per minute counter (Digital RPM Counter). The 4-Digit LED Display RPM comes with a magnetic proximity sensor switch.
