SparkFun Rotary Encoder - 1024 P/R (Quadrature) General Vehicle Electronics Accessories These are great little pliersThis 1024 pulse per rotation rotary encoder outputs gray code which you can interpret using a microcontroller and find out which direction the shaft is turning and by how much. This allows you to add feedback to motor control systems. Encoders of this kind are often used in balancing robots and dead reckoning navigation but it could also be used as a very precise input knob. Features: Resolution: 1024 Pulse Rotation Input Voltage: 5 12VDC Maximum
