zoomkat:
Instead of a long run of USB cable, you should try the long run of wire using regular wire between the arduino and servos. I've used cat3 four conductor wire to control servos at a distance. One conductor for common ground, one conductor for servo power, and the remaining two wires for the servo PPM control signals.
Hi zoomkat,
i also thinked as same as what you're thinking but my problem is:
this Pan-Tilt Pod is used for bear a USB camera. This camera i've used 5m cable to extend already.
And i want to anchor the Arduino with the Pan-Tilt Pod, finally i have to use 2 5m USB cable for my PTZ camera system :D.
If i use ethernet cable for extend the length between Servo and Arduino, my system becomes distributed, one end have Servo+USB Camera, one end have Arduino , also 2 cable type (USB + CAT)
