    I have a PIR Motion Sensor and have connected it up to a 9v battery. all is well! the next part my tutor says, is that i should connect a motor up so when the LED light comes on, on the sensor it makes a motor spin round.

    Any ideas how? what resistors i need etc?

    Maplin woundnt help me. :(

    Not too much information to work with. Does the sensor have a relay that closes contacts when it detects motion? If so, you can just use it as a switch to put power to your motor.
