Description
The potentiometer module is an analog rotational input device that allows users to control voltage output by turning a knob. Unlike a rotary encoder, this module provides a continuous analog signal corresponding to the knob’s position within its mechanical range
Key Features
- Analog Output: Provides a variable voltage from 0V to VCC
- Position-Based Control: Outputs absolute position (not incremental steps)
- ~280° Rotation Range: Limited mechanical rotation with end stops
- 3.3V–5V Compatible: Works with Arduino, Raspberry Pi, and more
- Simple Interface: Easy to connect using analog input pins
-
Beginner-Friendly: Great for learning analog sensor principles
