Firmware and tools for Arduino based 24 buttons midi controller

see it in action here

Install DualMocoLUFA on the Arduino 8U2's chip (look inside the dualMocoLUFA folder in this repository to find code and instructions)

no schematic yet, sorry.

• the 24 Arcade buttons are read by 3 74HC165 shift registers connected on Arduino's pin 2(LOAD), 3(CLOCK), and 4, 5, 6 (shift registers DATA)
• 2 x 7 led digit display are controlled by 2 74HC595 shift registers connected on Arduino's pin 9(LATCH), 8(CLOCK) and 10(DATA). These shift registers are set in series.
• two menu button on the side are connected to Arduino's pin 11 and 12 (with a pullup resistor)
