I need to connect a non-Lego motor to the RCX, and use an external power supply such as a 9V battery to drive the motor. Any suggestions as to how I should do this? (23 years ago, 16-Feb-02, to lugnet.robotics.rcx)
(...) If the motor runs on 9V anyway, just hook it up to RCX directly (assuming it only draws 500ma). If it needs more than that, hook an external battery up to it via a power transistor (either bipolar or FET). You'll need a resistor in series with (...)
