Hello,
Everything on my boe bot works, exept the servomotors
who doesn't turn. I tested my servomotors on an other robot,
and it worked.:confused:
What could be the problem?
Thanks to respond to me.:smilewinkgrin:

    More information is required. For now, check the batteries and check the polarity of the cables plugged into the BOE. What program are you using?

    I am using PBasic, but how can I change the polarity?:confused:

    You are following the connections in the book so just double check. The servo has color coded wires for ground, voltage, and pin as stated in the manual.

    Ok, but I didn't understand the little thingy you can put on position vin or vdd.

    Vin is the voltage directly from the battery supply and Vdd is a regulated +5 volts. You have the BOE board, right? What little thingy? Are you looking at the book? See Roboticsv2_2.pdf free for download at the Parallax web site.

    Thanks, now it works!
    But the wheels are turning, stopping, turning, stoping...
    What should I do?

    Adjust the delay in the code for the servo motors loop.
