//Example for KY-026
int Led = 13 ;// define LED Interface
int buttonpin = 3; // define the flame sensor interface
int analoog = A3; // define the flame sensor interface
int val ;// define numeric variables val
float sensor; //read analoog value
void setup ()
  pinMode (Led, OUTPUT) ;// define LED as output interface
  pinMode (buttonpin, INPUT) ;// output interface defines the flame sensor
  pinMode (analoog, INPUT) ;// output interface defines the flame sensor
void loop ()
  sensor = analogRead(analoog);
  Serial.println(sensor);  // display tempature
  val = digitalRead (buttonpin) ;// digital interface will be assigned a value of 3 to read val
    if (val == HIGH) // When the flame sensor detects a signal, LED flashes
    digitalWrite (Led, HIGH);
    digitalWrite (Led, LOW);
