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 ...

Existing Arduino tachometer code that is flowing around the internet give erratic readings even when the IR sensor is properly debounced. They are not useful for speed sensitive devices like a ...

The purpose of this tool is to measure any rotation speed with the same accuracy as a commercial product, it can also blink at afrequency defined by the user to match the roatation of anything up to ...

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 ...

We’re certainly no strangers to unique timepieces around these parts. For whatever reason, hackers are obsessed with finding new and interesting ways of displaying the time. Not that we’re complaining ...
