Clap to Turn On The Light!

INTRODUCTION

When I was young, I always have this kind of thought “Can I just switch off the light when I was about to sleep on the bed without going to the switch and turn it off?”. (I’m a bit scared when I sleep alone without my sibling) Hihi.. Then today, I found out that it’s actually doable to turn on and off the light by clapping my hand. Now, let’s have a look on how to do it!

int value = 0;
int flag = 0;

void setup() {

void loop() {
  value = digitalRead(SoundSensor); // To get the Sound Sensor's value

  if (value == 1) {

    if (flag == 1) {
      digitalWrite(yellow, HIGH);
      flag = 0;
    }

    else if (flag == 0) {
      digitalWrite(yellow, LOW);
