Project - 7 :- Clap Switch By Using Arduino


                                    PROJECT – CLAP SWITCH

In this tutorial you will learn how to use a Sound Sensor with Arduino and glowing a LED and beeping a Buzzer by Clapping.

                                                     STEP – 1: Components

Components Required:-
1.    Arduino Uno.
2.    Breadboard.
3.    Sound Sensor.
4.    LED
5.    Buzzer
6.    Wires         

                                       STEP – 2: Circuit

Clap Switch Output By Using Arduino
The connections are pretty easy, see the image above with the breadboard circuit schematic.


.                                              

                                       STEP – 3: Upload Code

int LED = 4;   //LED connected to pin 4
int micPin = 2;   // Mic connected to pin 2
int micVal = HIGH;      //HIGH is no sound, LOW is sound
boolean pwrToggle = true;
void setup ()
{
  Serial.begin(9600); 
  pinMode(LED, OUTPUT);  //Set pin for output
    digitalWrite(LED, HIGH);  // HIGH is off, LOW is on
  pinMode (micPin, INPUT) ;   //Set pin for input
}
void loop ()
{
  micVal = digitalRead (micPin) ; // Listen...
 
  if (micVal == LOW) // Hear something!!!
  {
      if (pwrToggle == true) {      //relay off (true) Turn it on and display message in serial Monitor
            Serial.println ("LED off");
            digitalWrite(LED, LOW);
            pwrToggle = false;
            delay (500);
      } else {    //relay on (true) Turn it off and display message in serial Monitor
            Serial.println ("LED on");
            digitalWrite(LED, HIGH);
            pwrToggle = true;
            delay (500);
      }
  }
}

      /* Copy above Code and Paste in Your Arduino Sketch */

                               Step 4: Well Done!

Clap Switch Output
You have successfully completed one Arduino Project and you learned how to use a Sound Sensor with Arduino and also learned how to on and off LED by Clapping.





                                                                                                               

               THANKYOU!

Project - 13 :- LED MATRIX By Using Arduino

                                PROJECT – LED MATRIX In this tutorial you will learn how to use LCD with Arduino and display some text on the LCD.                                                     STEP – 1 Components Components Required:- 1.      Arduino Uno 2.      Breadboard 3.      LED MATRIX 4.      Wires.                                          STEP – 2: Circuit The connections are pretty easy, see the image above with the breadboard circuit schematic.                                      STEP – 3: Add Library Before you can use the LED Matrix on the Arduino, you’ll need to install the  library. It’s easy to install, open up the Arduino IDE. Then go to Sketch>Include Library>Manage Libraries>search LEDCONTROL>install LEDCONTROL library.                                            STEP – 4 : Code #include "LedControl.h" #include "binary.h" /* DIN connects to pin 12 CLK connects to pin 11 CS
