Lesson 97-2: Controlling a Servo Motor Using a Rotary Encoder

In this lesson, we learn how to use a rotary encoder knob. Then we learn how to use it to control the position of a servo motor (97-2). In this lesson (97-3), we also display the position of the servo motor on an LCD screen using Arduino. This code will work with all Arduino boards. This code (97-2) demonstrates using a rotary encoder to control the position of a servo motor. When pressing the rotary encoder push button, it returns the servo to the home position. See the video for a demonstration.
