Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, an HC-SR04 Ultrasonic Sensor, and a 16x2 I2C LCD display. The Arduino UNO serves as the central controller, interfacing with the ultrasonic sensor to measure distance and displaying the results on the LCD screen.

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.
