Add a Cool Features to USB Speaker
In this project, I have added an extra feature to a simple USB speaker.
How It Works
Materiel Required
1) BC547 Transistor X3
2) 100K Resistor X1
3) 10K Resistor X2
4) 104 Ceramic capacitor X1
5) LED X2
6) Dotted board
Open Your Speaker
Make Circuit Board
I have made PCB. You can make PCB or you can make circuit board using a dotted board.
If you don't know how to make PCB, watch these video.

These are PCB files:
Connection
Connect your pcb with audio signal and 5V power supply.
Note: Don't connect any connection with IC output or input.
Make Hole
Make two holes for attaching LED.
Connect LED and Fix It
Solder some wire with LED to freely attaching LED anywhere in the speaker.
Now fix these LEDs using a glue gun.
