Motion Sensor With LED's

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

There are commercially made units which can do what you want. They're not expensive. However, it sounds like you're doing this because you enjoy it. If that is the case, try some of the ideas at Discover Circuits. They have simple DIY plans for several circuits you can try. Here's a URL:
