The Servotor32 can handle 32 servos and attaches to an Arduino board like the other shields. Is there a reason you wouldn't use this instead of a BASIC board that you would have to create and build to handle more than a few servos?
The reason I'm asking is that I am designing a life form animatronic that will need between 16 and 20 servos, be battery driven, and have several sensors that will cause reaction to near objects and touch sensation.
Arduino just seems to have more sensors and add-on boards than BASIC. BUT, I am also looking for advice. The tutorial mentions Arduino, but then speeds away without ever commenting on the boards.
