Measure motor speed (RPM) with Optocoupler and Encoder disk
STORY
When building a robot car, it is important to control the speed of the rotation of the wheels. Before we can control the speed however, we need to be able to measure it. One of the easiest and most popular ways of measuring the speed is with Optocoupler, and Encoder Wheel. Most of the Smart Car kits come with Encoder Wheels included, and I already made Tutorial on how to connect Optocoupler to Arduino. Now I will show you how you can use the Optocoupler to measure the rotation speed of the wheel.
