The Angle is a rotary switch unit which includes a 10K Ohm potentiometer inside. This unit can be used for continuous signal rotatory control for applications such as volume, brightness, or motor speed. A potentiometer is a manually adjustable variable resistor with three terminals. Two terminals are connected to a resistive element, and the third terminal is connected to an adjustable wiper. The position of the wiper determines the output voltage. The out voltage is captured and converted by AD on ESP32 on portB. In the M5Stack product system, normally the Grove colour indicates the type of communications. Black: Single BUS (AD ,DA ,GPIO) Red: I2C Blue: Uart White: Others (depends) The Unit\’s Grove interface is black, specify it is an analog interface that should be connected to the M5Core\’s GROVE B interface.
