The board itself can take Arduino ... module.) The board has power and ground pins, along with three pins. One of the pins is a switch closure to ground when you depress the shaft of the encoder.

He shows how to use a stepper motor as an encoder. You can see a video of the setup below. It makes sense. If the coils in the stepper can move the shaft ... code to let an Arduino read the ...

the module was connected to an Arduino board and measured the rotation per minute (rpm) rate of a geared robo motor (150rpm@5V) with the help of a home-made encoder disc (resolution 12 slots/disk) ...

Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style) ...
