Hello Everybody,

Today am going to Show you something interesting. I hope you all Enjoy this..:) 🙂 😀

Sound Sensor has the ability to turn ON any electrical component or circuit by the sound. The condenser mic which will be used in this Project will have an ability to take the sound as the input. It can be any sound. We can also say that it converts the Sound energy into the Electrical Energy, because we are giving an input to the circuit as a sound whereas the Circuit gives us the output as a LED glow (Electrical Energy).
Today however we are going to use hook up the sound sensor to an array of LED lights which will beat with music, clapping or knocking.


  • Arduino Board– I used the Arduino Uno
  • Some Wires
  • A breadboard
  • A sound sensor – Here i used Condenser Mic
  • At least 1 LED light – I used “13” LED.
  • Resistors – 10 k

We Have finished!

Now Start some music and see the awesome lights blink with the beat of the sound!

Here is a Video How it work !
