Introduction: Music Reactive Light Using BC547 Transistor
Today I am going to make music reactive light.The light will glow according to the sound.
Let's get started,
Step 1: Take All Components As Shown in the List and Picture
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
Step 2: Connect All Components
Connect all components as shown in the circuit diagram.
Step 3: Solder Both Transistors
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.
Step 4: Solder 10K Resistor
Next solder 10K resistor to collector of 2nd transistor as picture.
Step 5: Next Connect 1M Resistor
Next solder 1M resistor as you can see in the image.
Step 6: Connect Capacitor
Now connect -ve of capacitor to the base of 2nd transistor as shown in picture.
Step 7: Again Solder 10K Resistor
Again solder 10K resistor to the circuit according to circuit diagram and as you can see in the picture.
Step 8: Connect All LEDs in Series
Now Connect all LEDs in series as picture.
Step 9: Connect LEDs to the Circuit
Now connect LEDs to the circuit by matching its polarity.In picture you can see the polarity.
Step 10: Connect Mic
Next solder microphone wire to the circuit as picture.
Step 11: Connect Battery Clipper Wire
Next solder battery clipper wire to the circuit as shown in picture.
Step 12: Circuit Is Ready
Now circuit is ready to work.
Connect battery to the circuit and use it.
Step 13: How to 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.
