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?
