Introduction :
Rotary Encoder Module is a continuously variable position sensor that reports the relative position of the shaft, the direction of rotation and if the shaft is depressed.
Rotary Encoder Module is an incremental encoder which means that it outputs a pulse each time that the shaft is rotated one detent (click).
The position is kept track of relative to the position that the shaft was in when the controller is first powered on, so it does not have a sense of a specific physical position, but from the software perspective it knows it has gone 5 detents from where it started.
Features :
- Working voltage: 3 – 5V.
- Cycles per revolution (CPR): 20.
- Encoder Technology : Incremental.
- Rotation : 360º free rotation.
- Easy interface
