Interacting with an angle sensor unit

The angle sensor unit uses a basic 10 Kiloohm (KὨ) potentiometer for rotary adjustment of providing control signals. A potentiometer is a three-terminal electrical component that provides a range of resistance values. The primary function is to provide voltage division of an attached voltage supply source to an electrical circuit. Figure 2.23 shows a typical potentiometer:

The angle sensor unit is shown in Figure 2.24. This potentiometer-based component attaches to the M5Stack Core’s B-port:

To fully understand the angle sensor unit’s potentiometer and voltage division, you can build an electronic circuit model using the original circuit schematic diagram, as shown in Figure 2.25:
