I think I'm going to try to connect my Nook Color (rooted with android 4.0 via n2a SD card) to an Arduino or atmega328P
to do this I'm following the follow tutorials
android to arduino:
arduino in C
I'm going to avoid using arduino programming software and stick to C/C++ in eclipse. Should help out.
The toughest part will probably be programing the android as it requires the use of Java. We shall see.
