Summary

This circuit integrates multiple sensors and actuators with an Arduino UNO microcontroller. The sensors include IR sensors, a motion sensor, and an ultrasonic sensor. The actuators include a micro servo and a piezo speaker. Additionally, an HC-05 Bluetooth module is used for wireless communication. The Arduino UNO serves as the central controller, processing inputs from the sensors and controlling the actuators accordingly.

Documented Code

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 used to initialize any settings or configurations, and the loop() function contains the main logic that runs repeatedly. You can add your specific logic for handling sensor inputs and controlling actuators within these functions.
