Yes the muio interface can be used to control the real-world easily and in several ways. Details will be added here but to tease you...

The digital pins can be used as outputs, plus the 8by16 board itself has 2 DAC outputs on it.

Need more digital i/o? Then extend the muio using digital IO chips which can give you another 64 (in groups of 8).

Want 64 channels of PWM signals to control motors?  Then check out the arduino slave system.

32 servo motors?  The muio has built n support for a 21 servo control board.

desperate for info? then nudge me to prioritise... just  mail me "interface" AT the websites URL (muio.org).
