    Fix Your NordicTrack Exercise Bike

    Hi, more than likely the board, but to test you can disconnect the the motor from the wire harness and test by taking your ac to dc adapter and trying to connect the wires to the ac adapter to see if the motor turns. If the motor moves the adjuster then your board is at fault. Then your best best is to do the conversion that I posted.ThanksJoe

    Yes, your are correct, a momentary press on the switch would increase the tension. Yes it does look like your board is faulty. Use the wire diagram I posted then you can run the adjuster in or out to tighten or loosen the adjuster. Tension is totally arbitrary, based on how long you hold the switch.

  • Make:it Robotics Starter Kit – Driver board Familiarization

    The arduino pins do not control the motor driver board. The Arduino communicates to the driver board using the serial port. Look at the blue lined connector, this allows you to upload programs to the arduino when the jumper is removed and when back in place allows the arduino to communicate to the driver board. Look at the linefollowing program and the library c code code on how to communicate to the motors.Thanks
