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

Hii friend,

Today I am going to make awesome sound generator circuit using RGB LED and BC547 transistor. This circuit gives sound like as bicycle horn.

Let's get started,

Step 1: Take All Components As Shown Below

Components required -

(1.) Transistor - BC547 (NPN) x1

(2.) RGB LED - 3V x1 (Changing color RGB LED)

(3.) Resistor - 330 ohm x1

(4.) Resistor - 100 ohm x1

(5.) Buzzer x1

(6.) Battery - 9V x1

(7.) Battery clipper x1

Step 2: Connect 330 Ohm Resistor to the Transistor

Firstly we have to connect 330 ohm resistor to the transistor as solder in the picture.

Pinout of BC547 transistor : - Pin-1 is collector, Pin-2 is base and pin-3 is emmiter pin.

# Solder 330 ohm resistor between base pin and emmiter pin of this transistor.

Step 3: Connect RGB LED

Next we have to connect RGB LED to the circuit.

Solder +ve leg of RGB LED to collector pin and

-ve leg to base pin of the transistor as you can see in the picture.

Step 4: Connect 100 Ohm Resistor

Solder 100 ohm resistor between +ve & -ve pin of the Buzzer as solder in picture.

Step 5: Connect Buzzer to the Circuit

Next Solder -ve pin of buzzer to collector pin of the transistor.

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 pin of Buzzer and

Solder -ve wire of battery clipper to emmiter pin of the transistor as you can see in the picture.

Step 7: Circuit Is Ready

Now our amazing sound generater circuit is ready.so connect battery to the battery clipper.

Result : Buzzer gives sound like as bicycle horn.

this type we can make amazing sound circuit using BC547 transistor and RGB LED.

Thank you
