i have a problem with my thesis project. i'm currently using pic24 as my microcontroller. I'm using the parallax motor mount and hb-25 motor controller.

When i tap the ground of the motor controller to the common ground of the system, the motor turns on, full forward or full backward although it does not respond to the program of the microcontroller. but when i insert it to the pin it does not.


please help me here.

thanks!

    Ralph,

    Please clarify your connections…where does +, -, M1 and M2 all connect to in your system? Also, where does you B, R and W connections terminate to?
