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


An excellent sensor for this application would be single pole single throw
switch, as you wave your hand make contact with switch to turn on or off...
