Hi, You can check the link of how to hook up servo (look for by Gary Livick's contribution): (URL) will be easy if you have HB Expansion board since you just connect the servo directly into it. The servo library is already there for the expansion (...) (22 years ago, 20-Feb-02, to lugnet.robotics.handyboard)

Your simplest path to using these with the HB is to get an Exp Bd. Barring that, you (...) (22 years ago, 7-Feb-02, to lugnet.robotics.handyboard)
