Circuit Documentation

Summary

This circuit involves an Arduino UNO microcontroller, three 5V relays, three AC bulbs, and three touch sensors. The Arduino UNO controls the relays, which in turn control the AC bulbs. The touch sensors are used to trigger the relays via the Arduino.

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 used to initialize any settings, and the loop() function contains the main code that runs repeatedly. In this case, the code is currently empty and needs to be filled in with the logic to control the relays based on the touch sensor inputs.
