Abstract

This study aims to facilitate the calculation of rotational speed so that it can be used as a practical tool for students. The method used is to design hardware consisting of Arduino Uno R3, Lm393 IR Speed ​​Sensor Module, DC Motor, I2C LCD. Then connect with a USB cable to the laptop and run the coding. The trial was conducted twice. The speed captured by Lm393 will be read on the I2C LCD. In the first trial the speed was not constant. Whereas in the second trial the speed produced is constant.
