IOT Project Blinking LED by Clapping using Arduino UNO

Step by Step by Procedure:

Arduino to Relay

Step 1: Connect Arduino GND pin to Relay GND pin.

Step 2: Arduino 5v to relay bcc

Step 3: Arduino digital pin 4 to relay pin 1

Step 4: Arduino pin 5 to relay pin 2.

Step 5: Arduino pin 6 to relay pin 6

Arduino to Sensor:

Step 1: Arduino GND pin to sensor GND pin.

Step 2: Arduino 5v to Sensor bcc

Step 3: Arduino pin 2 to digital output(D/O)

IOT Project Blinking LED by Clapping Code:

const int Sensor=2;

const int relay =4;

int x=0;

int y=0;

void setup()

{

pinMode(relay, OUTPUT);

pinMode(Sensor, INPUT);

}

void loop()

{

x=digitalRead(Sensor);

y=digitalRead(relay);

if(y==HIGH && x==LOW)

{

delay(250);

digitalWrite(relay,LOW)

}

if(y==LOW && x==LOW)

{

delay(250);

digitalWrite(relay, HIGH);

}
