this instruction would show how you can make your own music light box that react with sound.
1-we have the power supply section, which takes the power from a USB port and store it in the battery.
2-we have the switch which then either takes the power source to the amplification circuit which amplify the sound, or to the 555 timer circuit which does the fade in/out operation.
3- these 2 different circuits send the signal to the LEDs. and that's it. have fun
