SunFounder ESP32 Starter Kit
1.24 5.8 Turn the Knob
A potentiometer is a three-terminal device that is commonly used to adjust the resistance in a circuit. It features a knob
or a sliding lever that can be used to vary the resistance value of the potentiometer. In this project, we will utilize it to
control the brightness of an LED, similar to a desk lamp in our daily life. By adjusting the position of the potentiometer,
we can change the resistance in the circuit, thereby regulating the current flowing through the LED and adjusting its
brightness accordingly. This allows us to create a customizable and adjustable lighting experience, similar to that of a
desk lamp.
