Heart Music Reactive Light

Hii Friend,

Today I am going to make a circuit of Heart Music reactive light in which when music will play around this circuit then LEDs will be glowing as music.

Let's get started,

Components required -

(1.) Transistor - NPN (2N222) x1

(2.) LED - 3V (Any color) x{As LEDs required to make heart.It will depend upon the size of the heart}

(3.) Mic x1

(4.) Resistor - 33K x1

(5.) Battery - 9V x1

(6.) Battery clipper

Firstly we have to make Heart of LEDs as you can see in the picture.

NOTE : Legs of LEDs connect in Parallel (Connection will be +ve of all LEDs to each other and -ve of all legs of LEDs to each other).

~Use Cardboard to make this Heart of LEDs.

Next we have to connect transistor to the Heart of LEDs.

Solder Collector pin of Transistor to -ve pin of LEDs as you can see in the picture.

Next we have to connect 33K resistor to the circuit.

Solder 33K Resistor between base pin of transistor to the +ve legs of LEDs as solder in the picture.

Next Connect the wires of MIC.

Solder +ve wire of mic to the Base pin of transistor and

solder -ve wire of Mic to emmiter pin of the transistor as you can see in the picture.

Next we have to connect battery clipper wire to the circuit.

Solder +ve wire of battery clipper to +ve legs of LEDs and

Solder -ve wire of battery clipper to Emmiter pin of the transistor as solder in the picture.

This Heart music reactive light circuit is ready.

To use this circuit connect 4V Battery to the Circuit and say somethig/play music.

As music will give sound like that LEDs will glow.

NOTE : We can give Input Power supply (4-6)V DC.Here I used 9V Battery for demonstration purpose.Please you don't use 9V Because transistor can be damage.

Thank you
