    using a larger picaxe chip to control 2 AXE031 servo controllers

    Hello! I have made a 1.2meter long humanoid robot arm that uses 4 300kgcm 20v geared motors, for the shoulder, with servo controllers added (Basically converted to servos) and 7 hobby servos for the fingers and wrist articulation. So far, I have managed to get it to work with a 4X3 keypad...

    Please advise. 2 switches and 2 motors

    Bit of a newie question, sorry >___< I have an AXE023 motor driver. I wanted to rig up 2 switches / buttons, and 2 Motors. I later read the data sheet properly, after moving the jumpers around etc, and realised that you can only have either one motor and 2 switches, or 2 motors and one switch...
