void setup()

{pinMode(Led,OUTPUT);// Define LED as output interface

pinMode(buttonpin,INPUT);//Define D0 Sensor as output Interface }

void loop()

{val=digitalRead(buttonpin);//digital interface will be assigned a value of 3 to read val

if(val==HIGH)//When the light sensor detects a signal is interrupted, LED flashes

{digitalWrite(Led,HIGH)}

else

{digital Write(Led,LOW)}}

int sensorPin = A5; // select the input pin for the potentiometer

int ledPin = 13; // select the pin for the LED

int sensorValue = 0; // variable to store the value coming from the sensor

void setup() {pinMode(ledPin, OUTPUT);Serial.begin(9600);}
