Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino UNO microcontroller, a touch sensor, and a traffic light module. The Arduino UNO serves as the central processing unit, controlling the touch sensor input and driving the traffic light outputs. The touch sensor is used to detect touch inputs, and the traffic light module simulates a traffic signal with red, yellow, and green LEDs.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
