1) MOCO is one of alternative irmawre for Mega8u2/16u2. By replacing the original firmware on Mega8u2/16U2 with Moco, Arduino Uno will act as USB-MIDI device (Standard Midi Class), which is suitable to build music instruments and devices.

2)
Moco is a bridge program which converts USB-MIDI packets to serial MIDI signal, and vice versa.
It will receive serial MIDI from Arduino’s main processor and send them to PC as USB-MIDI packet. It will receive USB-MIDI packets from PC and send them to Arduino’s main CPU as serial MIDI signal.

In many cased, Arduino MIDI Library is used for the development of MIDI device for Arduino MIDI. Moco is compatible with Arduino MIDI library.


3) In order to write a program to Mega328, the original firmware for Mega8u2/16U2 is required.
Install dualMocoLUFA firmware to Mega8u2/16U2

2. Write your program with Arduino IDE

Before connect Uno to PC, install a jumper between pin4 and pin6 on ICSP connector for Mega8u2/16U2. With the jumper, Arduino-serial mode is initiated. You can use Arduino IDE to program mega328 on Uno.

Try your program with USB-MIDI firmware

Disconnect Uno and remove the jumper, then connect Uno again. This will initiate USB-MIDI bridge mode of dualMocoLUFA. At this step, you can verify the device works as USB-MIDI. At this time, you can try your application as USB-MIDI device .
If sometings goes wrong, back to step 2 and modify your program.Follows the instructions described step2, then reprogram Mega328 with Arduino IDE.

Using an Arduino Uno R3 as a Game Controller

Arduino uno does not really support keyboard strokes.

You will need:
1)Arduino Uno
2)Any sort of button or switch (or multiple switches, but start off simple)
3)10kΩ resistor(s) (one for each button)
4)Eclipse (the front end for Java programming - instructions later on for install)
5)Arduino Software (the front end for Arduino programming)
6)Breadboard
7)Jumper wires
8) Any video game that you may want physical switches for (racing/flight sim)

Step 1 : install ecplise and arduino uno software
In the Arduino software, click tools and make sure the board and port number make sense according to Device Manager. To test the board, goFile>Examples>Basic>Blink then hit the arrow in the top left that says upload. If all goes right, the SMD on pin 13 should be blinking

step 2 : Wiring up basic switch and programming
