Step 13: Software
There is software to be loaded on to the Arduino1 (which reads the Nunchuck data).
There is software for the Arduino 2 which is a modified form of the TVout software that produces the picture on the screen. It also displays the menu of letters to select with a small cursor that moves under each letter and sends the selected words out to the text-to-speech module.
See video on page one and you will get the idea how this works.
The reason both parts of the software are not all on one arduino is that it will not work and the picture will "crash". I think this is because the TVout software uses a lot of RAM just to create a picture on the TV.
Both Arduino "Sketches" are attached.
NOTE: the modified TVout sketch for Arduino2 is right at limit of the memory. If you for example print just a few more characters on the screen, it will crash. If you want to modify the code, remove anything non essential then build up your new code in very small steps, testing if it works after each small addition.
NOTE: To load a sketch onto Arduino 2 you need to disconnect the Tx and Rx wires from the Arduino that go to the speech module. I could have avoided this by using some other pins to connect to the speech module and using the "software-serial" library - but this would stop the TVout working - I know as I have tried it.

what would you need to change to the code in order to make it work with EMIC2
