Motion Sensor With LED's

[sizz1@xxxxxxxxxxx]

Hi,

Im having some difficulty trying to make a circuit.
I want to create a desk lamp which only switches on/off when you wave
your hand across the sensor.

I will be using
4x AAA batteries 1.5v Each 1150mAh
8 LED 3.6 Forward Volts - 20mAh
120 ohm Resistors

Not sure about the sensor and other components..

Please can someone help me specify the materials and circuit layout.

Thanks
