I am intending to use a total of 19 servo's in my robot. 1 servo to sweep the
Ultrasonic pic sensor, and the other 18 servo's for the legs and movement of
the robot. Ive read in the tutorial for connecting the ping sensor, that I will
need to hook it up to 2 I/O ports. But with 19 servo's connected on the board,
I would only have 1 digital port left.
I notice those 8 additional analog ports on the board, is it possible to use those
analog ports and connect servo's or sensors to those? I was thinking of maybe
adding a speaker or some leds if possible. Can those analog ports be used for
such things too?
