Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller board and three identical Flame Sensors. The Arduino UNO is used as the central processing unit to read signals from the Flame Sensors and execute embedded code to perform specific tasks based on the sensor inputs. Each Flame Sensor is capable of detecting a flame and providing both digital and analog outputs. The sensors are powered by the 5V output from the Arduino UNO and are grounded to the same board. The analog outputs from the Flame Sensors are connected to three separate analog input pins on the Arduino UNO for individual flame detection readings.

Documented Code

The code for the Arduino UNO is written in the Arduino programming language (based on C/C++) and is used to initialize the microcontroller and repeatedly execute the main logic in a loop.

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

The code provided is a template and does not contain any specific logic for interacting with the Flame Sensors. To complete the circuit functionality, the user should add code within the setup() function to initialize the sensor pins and within the loop() function to read the analog values from the sensors and act upon them accordingly.
