Circuit Documentation
Summary of the Circuit
This circuit is designed around an Arduino UNO microcontroller, which serves as the central processing unit. The circuit includes a green LED, a resistor, and a potentiometer. The LED is controlled by the Arduino through a digital pin, with the brightness potentially being modulated by the potentiometer. The resistor is used to limit the current through the LED to prevent damage. The potentiometer can be used to adjust the voltage input to an analog pin on the Arduino, which could be used in the code to affect the LED's behavior or for other input purposes.
