 		 #172615 - RE: running 32 servo motors
Responding to: ???'s previous message
Per Westermark said:
Concept of running 32 servo motors? Easy. Just build a chip with more hardware for PWM or similar.

Or have one chip dedicated to each motor; with, probably, a microcontroller to coordinate them all...
