Hi. I need help with my Servocity SPT200 Pan and Tilt mechanism hooking up to the Micro Maestro. I am using Hitec HS-485HB servos in it. I have the Micro Maestro hooked up to the USB, and only have the one servo hooked up in the Servo 0 spot right now. I have put a Futaba NR-4J 4.8v battery in to power the servo on the pins above the Servo 0 pins. I ran your first “blink the red led” test and everything worked fine. I then ran this program:
# Move servo 0 to five different positions, in a loop.
4000 0 servo # set servo 0 to 1.00 ms
5000 0 servo # 1.25 ms
6000 0 servo # 1.50 ms
7000 0 servo # 1.75 ms
8000 0 servo # 2.00 ms
The servo moved- once. After that I have tried several things ( changed servos, changed baud) but have gotten no more response. My initial guess is that the battery is kind of old and may need charging- but I hope its something in the coding or the way I have hooked it up is wrong. Any thoughts? Thanks for your help in advance.
