DIY Simple Music Operated LED Lights

In one of our previous circuits, we have built a Dancing LED circuit, which just follow a set pattern and we can only control the speed. Now we are taking this to next level, in this Music Operated Dancing LED Circuit, in which LEDs will flash according to music, just like Disco lights. This circuit is based on transistor BC547. This circuit is very simple and easy to build, it just requires few basic components and it looks very cool.
