ok, i have found what i mean on the internet now, but this doesn't seem to be a standalone unit, i have emailed these people asking them how it was made or if it can be modified and used as one, but they wont tell me!! i would like to buy this unit. but as its for an A level project i cant, as i obviously wouldn't get a grade for making something i bought./
does anyone know how i can make this myself. very simply without an PIC controller or anything, as simple as possible. As it has to look like i could make it, as im in my 1st year of a level

If u watch the video you will see what i meen, just when something passes a sensor of some kind then a led is illuminated.
i have looked at light dependent resistors but this need to work in light and dark so there is an issue with them.
thanks alot
