Hello guys , in this post we learn how to make launchpad using ardunio uno and nano
Let,starts it
*Parts list:-
1.Ardunio uno/nano
2.push buttons
3.diode(In4007)
4.WS2812B
*Schematic and diagram
-connect all components according to this schematics
*lets code time
In this code you should add these library in ardunio ide
1.fastled
2.keyboard library
-Copy The following code in ardunio ide

-upload the given code in ardunio
*let we need some software to communicate with ardunio
1.Hairless MIDI
2.loopMIDI
so,you connect with ardunio and enjoy
if any problem you faced contact me i help you,
