Arduino Beginner Series: Project 7: Turn LED on/off with a clap

Hello everyone!! Welcome to this post on Arduino LED Projects!!
Need a short introduction to what the Arduino is then click on LINK
Check out the breadboard intro right HERE

So Let’s get started!!

Demo:

This is what my project looks like:

Things Required:

1. Arduino UNO
2. LED (any colour)
3. Breadboard
4. 220 ohm resistor
5. KY-038 sound sensing module
6. Jumper Wires
7. Arduino IDE on computer

Functions Used:

1. digitalRead()
2. digitalWrite()

Reference Material:

I used the following (LINK) as a reference.

Code:

int led=9;
int sound=10;
int j=0;

void setup() {
  // put your setup code here, to run once:
  pinMode(led, OUTPUT);
  pinMode(sound, INPUT);

}

void loop() {
  // put your main code here, to run repeatedly:
  if(digitalRead(sound)==HIGH){
    j++;
  }

  if(j%2==0){
    digitalWrite(led, LOW);
  }

  if(j%2!=0){
    digitalWrite(led,HIGH);
  }

}
