Arduino+Ben NanoNote Howto & Video Clip :P
¡¡¡Be aware!!!, The procedures described below will void the warranty of Ben NanoNote and can cause irreparable damage to the device, if you decide to go on is on your own responsibility.
OK, once advised, let go for it :)
First is to have available the serial port of Ben NanoNote, only the pads under the battery are really needed to be soldered, this ones are "easy" if you have some previous experience soldering boards, the other soldering points described in there are optinal and harder to get it right, I not recommend to use them if you not really really know what you are doing and had the nessesary equipment.
This sketch is basically "spiting" stream of data when it starts, (ASCII chars form 33 to 125) and then wait for the qwe char sequence to change the status of the led (ON if OFF and OFF if ON).
The wiring schema is the following:

Power on the NanoNote with S pressed to enable the serial input on NanoNote (dissabled by default)
Access to one console on ben and... you can see on the video next steps ;), in fact you have a Linux connected to Arduino so all in Arduino Playground relative to Linux is , theorically, applicable, we will continue digging on it :), Enjoy the music :)
