[PD] electro-mechanical piano (player piano) - Arduino, Solenoid Issue

[Epic Jefferson]

Hey guys,

I've had progress building an Arduino-powered solenoid system for a
controlling a piano's hammer mechanism (removing the keys) via pd.
So far I've found the solenoid I want to use. [image: Inline image 1]
Does any one have experience daisy-chaining arduinos (or arduino mega's) to
get more pwm pins, while using just one usb connection for controlling via
pd?
