## Description

**ANGLE** is a rotary switch Unit which 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 M5Stack product system, Normally the Grove color indicates the type of communications.*

- Black: Single BUS (AD ,DA ,GPIO)
- Red: I2C
- Blue：Uart
- White： Others(depends)

## EasyLoader

>EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification. Please install the corresponding driver according to the device type. M5Core host [Please click here to view the CP210X driver installation tutorial](en/arduino/arduino_development), M5StickC/V/T/ATOM series can be used without driver)
