Remeber also that you have to cut the motor power trace and use an external 5V source for the motors in this case. The HB itself will output 9.6 V from the motor ports. (...)

I'd like to build a six legged robot. that would need at least 12 servos. Is there a way to control 12 servos or more with the standard handyboard? someone said it's all in the code (using digital outputs) does that mean I could write the code to do (...)

The base Handy Board is designed to control 4 DC motors. The DC motor output ports CAN be used to control 4 (four) stepper motors. Remember that a stepper motor needs a square wave pulse continually sent to the motor for operation, and the mark / (...) (24 years ago, 17-May-00, to lugnet.robotics.handyboard)

(...) The deal is this: Servos are different from plain old DC motors. They have gearing and position control circuitry built in. There are four DC motor ports on the basic HB, but no ready-made servo ports. The dual servo routine described on the (...) (24 years ago, 17-May-00, to lugnet.robotics.handyboard)
