Halloween is a great time to put your engineering prowess to work on a fun project. For this special Halloween project, we built a spooky candy bowl that lights up when an unsuspecting trick-or-treater reaches in. Using a microcontroller and some aluminum foil, we can build a capacitive proximity sensor that detects when a person's hand is nearby.
For more details, explanations, and source code, please see:

@crackerjack850 i don't think so, the laser and the photocell is just too small...

I think you should also hook it up to a theremin, so it would go woooooo when you put you hand in too ;)

wouldn't it be easier to simply put the candy on the table, in plain view of the kids?

search digikey for the qt113, seems to be pretty handy for wrapping all this up and simplifying it.
