Hi all!

I'm rather new to pure data, and got inspired by this tutorial:

http://puredata.hurleur.com/sujet-5250-puredata-arduino-serial-tutorial

My problem is now how to add more sliders, and pins in order to cycle the full spectrum of colours?
I assume I will have to split the serial output of pure data, and somehow read multiple bytes on the arduino?

The sketch and patch I used as example, is already in this forum, from the bottom link above.

Thanks!
