Circuit Documentation

Summary

This circuit involves an Arduino UNO microcontroller interfacing with two HC-SR04 Ultrasonic Sensors, a buzzer, a red LED, a power jack, a Polymer Lithium Ion Battery, and a rocker switch. The circuit is designed to measure distances using the ultrasonic sensors and provide feedback through the buzzer and LED. The power is supplied via a Polymer Lithium Ion Battery connected through a rocker switch and a power jack.

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.
