Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller interfaced with a potentiometer and an LED with a series resistor. The potentiometer is used to provide an analog input to the Arduino, which can be used to control the brightness of the LED or other similar functions. The LED is connected to the Arduino through a 220-ohm resistor to limit the current and protect the LED from damage.

Component List

Potentiometer

• Pins: GND, Output, VCC
• Description: A variable resistor with three terminals. It is used to adjust the level of the voltage between VCC and GND.

Arduino UNO

• Pins: UNUSED, IOREF, Reset, 3.3V, 5V, GND, Vin, A0-A5, SCL, SDA, AREF, D0-D13
