Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller and a trimmer potentiometer. The Arduino UNO is used as the central processing unit, controlling the voltage levels on its digital pins to interface with the potentiometer. The trimmer potentiometer is connected to the Arduino and is likely used to provide analog input to the microcontroller based on its position.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
• Pins: UNUSED, IOREF, Reset, 3.3V, 5V, GND, Vin, A0-A5, SCL, SDA, AREF, D0-D13.
