Hi everybody, just finished assembling Arduino Boe Bot and trying out a few basic commands. It seems that after trying out a few sketches that The robot left wheel simply won't ever go backwards. Forward fine, Right Wheel forward and backward both fine, but no reverse on left side...any ideas where to check next? Thanks

    Swap your servo connectors to see if the problem is the board output or the servo.

    Make sure that you have run the center adjustment for both wheels. I've seen this cause a servo to only turn one direction.

    Thanks for those replies. It was the servo centering. I I think I copied the wrong sketch when calibrating that wheel, all seems to working now. Thanks again.
