Circuit Documentation

Summary

This circuit is designed to detect the presence of a flame using a flame sensor and control a relay and an LED based on the sensor's output. The Arduino UNO microcontroller is used to process the sensor data and control the relay and LED accordingly.

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 or configurations, and the loop function contains the main logic that runs repeatedly. In this template, no specific functionality has been implemented yet.
