Circuit Documentation

Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller, a red two-pin LED, a rotary potentiometer, and a resistor. The Arduino UNO is used as the central control unit, interfacing with the potentiometer and controlling the LED based on the potentiometer's position. The potentiometer provides analog input to the Arduino, which can be used to adjust the brightness of the LED. The resistor serves to limit the current through the LED to prevent damage.
