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 (...)

(...) Hi If you use the expansion board, you will loose analog input 0 und 1. These two inputs are multiplexed on the exp board, so you get some more analog ports. -Martin (26 years ago, 17-May-00, to lugnet.robotics.handyboard)

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 / (...) (26 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 (...) (26 years ago, 17-May-00, to lugnet.robotics.handyboard)

I am a new Handyboard user and would like to control a pair of 5 wire unipolar stepper motors. I followed the links in the FAQ related to steppers which included some IC code. My problem is that my Handyboard won't load that particular code written (...) (26 years ago, 16-May-00, to lugnet.robotics.handyboard)
