Digital RPM Tachometer with Arduino

Some time we required to check the RPM of motor while creating projects. Few days back when i was creating a project that time i required a RPM techometer to check the rotational speed of motor but did not have the RPM meter then i decided to make it myself as i know how to make it and i had all the equipment required. So in this article I am going to explain you about DIY Digital Tachomenter with Arduino.

This article is about DIY digital RPM tachometer, After reading this article you will be able to check the speed of dc motor or any kind of rotational device.

So just the take the advantage and update yourself.

Folloing things are required to make RPM meter.

1. Optical speed sensor

2. Arduino

3. OLED display

4. Breadboard

5. Jumper wire
