Heart Music Reactive Light

Introduction: Heart Music Reactive Light

About: Share diy projects to those who have the same hobby with me

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,

Step 1: Take All Components As Shown Below

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

Step 2: Make Heart of LEDs

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.

Step 3: Connect Transistor - 2N222

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.

Step 4: Connect 33K Resistor

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.

Step 5: Connect MIC

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.

Step 6: Connect Battery Clipper Wire

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.

Step 7: How to Use

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
