Build your own USB / VU meter and Bluetooth speaker with volume indicator.

I actually made a Bluetooth speaker that I can use at home. The sound is pleasant to hear. And if you watch the video carefully, there are small ideas and simple electronic circuits. I believe it will be a great help to those who are just starting out with electronics to study circuits. I tried to explain it as well as possible.
