• Connection: gpio
• Kit: hak

UPM module for the Grove rotary encoder. This rotary encoder encodes a rotation signal into electronic pulses that can be used to measure rotation and direction. It is useful in cases where a rotary knob is required, but using a potentiometer is not desirable. A rotary encoder can turn a full 360 degrees without a stop and does not place a resistive load on the circuit, as is the case with a potentiometer.

This module maintains a position that is incremented or decremented according to the rotation on the encoder.

        // Instantiate a Grove Rotary Encoder, using signal pins D2 and D3
        upm_rotaryencoder.RotaryEncoder rotaryencoder = new upm_rotaryencoder.RotaryEncoder(2, 3);

        while (true) {
            System.out.println("Position: " + rotaryencoder.position());

            Thread.sleep(1000);
        }
