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 ...

I needed a tacho/RPM display for a CNC spindle. I decided to use an Arduino Micro and OLED display with a reflective LED/Photo transistor as a sensor. Since powering up, a clock can display the total ...

A tachometer measures the rotation speed of motors and other machinery. There are various types of tachometers. Described here is a digital non-contact type tachometer using a proximity sensor. The ...

The “tachometer” module can be operated from any low-current, 8-18V, DC power supply unit/battery. The module provides a dedicated 5-pin connector for connecting a 3-wire, Hall-Effect chip based ...

The parts arrived for the RPM meter that uses an Arduino and reciprocal counting to get a three-times-a-second update rate with 1rpm resolution.
