So, i wanna clone a 'le strum'

Plan

Current 'plan' , port logic of lestrum to arduino , implement a capacitive touch sensor for strumming, implement something with 74hc595 to scan all the switches, combine with axoloti inside instrument? Maybe some knobs and leds and display(s) on the axoloti? hmm

I got buttons from KingOfDos, the nice keys also used on Wearable Computer 's current keyboard

Still need to decide on the form factor ... guitarshape seems logical, but maybe something else?

Got parts

• PIC16F1825 ( Might not be using these ... )
• Midi connector(s)
• 74HC595

• 2x Adafruit MPR121 capacitive touch breakouts (ordered 2016-03-11)
• Axoloti (unplanned extra)
