Rotary encoders are versatile devices that can be used both as controls and as instruments to measure the rotation of a DC motor. Today I will show you how to do both of those things using rotary encoders and an Arduino. • Complete article with code - https://dronebotworkshop.com/rotary-e... • More articles and tutorials: https://dronebotworkshop.com • Join the conversation on the forum: https://forum.dronebotworkshop.com • Subscribe to the newsletter and stay in touch:https://dronebotworkshop.com/subscribe/ • We will look at two types of rotary encoders today. The first one is a very common control that looks a bit like a potentiometer but, as you will see, is much more accurate and versatile. • The second rotary encoder we’ll examine is attached to the back of the DC Gearmotor I’m using to build my DB1 robot. • Both encoders work on similar principles. • I’ll show you how rotary encoders can determine both the position and direction of rotation by using and comparing two output pulses. Then we will create and run a few Arduino sketches to put them to use. • In the first sketch, we will see how to read the value from a rotary encoder control. Next, we will add a servo motor and precisely control its position with a rotary encoder. • After that, we will bring out the servo motor encoder. We will look at the output pulses on an oscilloscope, then we will connect it to an Arduino to build a tachometer of sorts, reading the RPM of the motor. • Here is the Table of Contents for today's video. • 00:00 - Introduction • 02:15 - Rotary Encoder Operation • 06:13 - Basic Rotary Encoder Control Sketch • 12:09 - Controlling a Servo Motor • 18:40 - Rotary Encoder on a DC Gear Motor • 21:08 - Reading RPM from a Motor • As usual, you will find all of the code in a detailed article on the DroneBot Workshop website. • And if you haven't subscribed to the YouTube channel then now is the time!
