This is a useful "control motor" version of the 92875 Tethered battery motor.
The motor can be programmed to go forwards or backwards via computer control devices such as
Learn & Go or FlowGo.
The unit comprises a motor in a clear case linked to a tethered lead, which terminates in 2 x 4mm plugs to connect the motor to the computer control device.
The motor should be operated with a voltage between 3v and 6v DC.
