5 Rotary Encoder Projects That Add Precision Input to Your Projects

5 Rotary Encoder Projects That Add Precision Input to Your Projects Build interactive control systems: digital volume knob, menu navigation, motor speed control, synthesizer sequencer, and playlist browser The KY-040 rotary encoder is an incremental encoder that outputs pulse signals as you rotate the shaft. Unlike potentiometers (which wear out), encoders give you clean digital signals that can count rotations in both directions. In this guide, we build five interactive control projects that us
