M5 Stack Mini Angle Unit with Potentiometer

ANGLE is a rotary switch Unit that simply 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, 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 M5 Stack product system, Normally the Grove color indicates the type of communications.

Black: Single BUS (AD, DA, GPIO)
