Check out the HB-25 product page for any sample code available.

irkris77,

·· Can you post the program that you sent me on the forums? Are you using 1 or 2 HB25 modules?

We are using 2 HB25 motor controllers one for the drive motors and one for the steering motor . We followed the RC time circuit example and used a potentiometer to track steering position. The major difficulty we are having is trying to get the motor to turn to a center position( or any position for that matter) that corresponds with the potentiometer.

Please and thank youu for any assistance

Might I inquire as to why you are using HB-25 controllers for Servo mtors? Seems to me a Servo PAL would serve the same purpose and are less expensive and you could use the H-25 for DC motors. Just curious!!!

I misspoke I am using a worm gear dc motor from a car seat. the reason for using it was it attaches easily to the shaft. However as the project has moved forward I am finding that there are better choices that make it easier to track position.
