Circuit Documentation

Summary

This circuit involves an Arduino UNO microcontroller interfacing with an IR sensor, a red LED, a green LED, and a buzzer. The IR sensor detects an object and triggers the LEDs and buzzer accordingly. The Arduino UNO serves as the central control unit, processing the sensor input and controlling the output devices.

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize your components and settings, and the loop() function is where the main logic of your program runs repeatedly.
