Arduino Based MIDI Fighter(Touch Sensitive)

MIDI stands for Musical Instrument Digital Interface. Here, we are making a touch sensitive MIDI fighter.
It has 16 pads. these can be increased or decreased. Here I have used 16 because of the limited arduino pins.
Also I have used analog input pins (A0,A1,A2,A3,A4) as digital input.
This is my first instructable. So pardon me for any mistakes. I haven’t thought of making a instructable earlier.
so I don’t have much detailed photos of that.
There is a working video of the MIDI I have selected guitar in sounds in the ableton live 9 software in the video.”
