I'm interested in building a voltage monitor circuit for my robot's
6V battery, and a current monitor circuit for the motors. Is there an easy
way to do this, with reasonable accuracy? I'd like to interface both of
them to the analog sensors on the handy board.

| (...) Use a voltage divider (two resistors) to map the battery voltage to a 0 - 5v signal for the A/D converter. Depending on how much current your motors draw, you can put a .1 ohm precision resistor in series with the motor and measure the voltage (...) (28 years ago, 4-Jun-96, to lugnet.robotics.handyboard)
