Hi,
I am working in a project with arduinos, xbees and puredata.
after somany days of research I was able to connect wireless a arduino to puredata without firmata.. my arduino has 6 analogs sensors and has the code from spikezinelabs running (arduino drums).
in my Puredata patch gets data from any sensor as a single input.
I woud like to separte the data for each sensor and make puredata bang to a software instrument.
any suggestion is very welcome.
arduino code and puredata patch here
puredata patch ( extended version)
