| | | | | (...) Erh, I'm not so sure about that? One side of the sensor input is ground, the other side is the input to the voltage measurement circuitry. The motor output on the other hand has two connection, which are either ground and +8(ish) or +8 and (...) (22 years ago, 9-Aug-02, to lugnet.robotics)

| | | | | Quoting Paul Andrews <paul@jools.net>: (...) How about a simple resistive divider across the motor output, say two 1 Kohm resistors, with the motor on the top of the two and the sensor input on the midpoint, so it sees the battery divided by two?
