Music Reactive Light Using BC547 Transistor

Hii friend,

Today I am going to make music reactive light.The light will glow according to the sound.

Let's get started,

Components required -

(1.) Transistor - BC547 x2

(2.) Capacitor - 63V 1uf

(3.) Resistor - 10K x2

(4.) Resistor - 1M x1

(5.) Mic x1

(6.) Battery - 9V x1

(7.) Battery clipper x1

(8.) LED - 3V x3

Connect all components as shown in the circuit diagram.

Firstly solder Both transistors -

Solder Base of 1st transistor to the collector of 2nd transistor

and emmiter of 1st transistor to emmiter of 2nd transistor as solder in picture.

Next solder 10K resistor to collector of 2nd transistor as picture.

Next solder 1M resistor as you can see in the image.

Now connect -ve of capacitor to the base of 2nd transistor as shown in picture.

Again solder 10K resistor to the circuit according to circuit diagram and as you can see in the picture.

Now Connect all LEDs in series as picture.

Now connect LEDs to the circuit by matching its polarity.In picture you can see the polarity.

Next solder microphone wire to the circuit as picture.

Next solder battery clipper wire to the circuit as shown in picture.

Now circuit is ready to work.

Connect battery to the circuit and use it.

Connect 9V battery to the circuit and play a song/ say something on mic.

According to the sound LEDs will glow.

Uses - when we play any song then we can use this circuit to see the light according to the music.

This type you can make Music reactive light at easily.

Thank you
