There is no better components than LEDs
So in this project i just made a Music Sensor that dances with the SOUND !!
Make sure you get the components before you start
PS : they are extremely cheap !!!

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Schematics
you can do any word you want in the PANEL
you can even write you're name if you want to
but just make sure to calculate resistor values prperly
because current changes with the number of diodes
Step 2: Solder the LEDS
solder all the leds in parallel and always check if there's a short circuit
Step 3: Solder the Components
follow the schematics above carefully and design your own board
Step 4: Add the Amplifier Stage
this stage is necessary because the signals coming out of your phone or whatever your playing music with
is so low that it dosen't trigger the comparators
Step 5: Enjoy Your Project
make sure to check all the voltages and pay close attention to short circuit before trying you project
then plug it in and enjoy
