Kids handheld sensor array

This little device really does nothing other than test your soldering ability. Lots of fun for the kids though. Mine runs around flipping the switches. It has been a monster detector, camp site detector, dog repeller, and anything he can come up with. I had fun soldering it together. Please make sure to include the resistors in your wiring. The LEDs are awfully bright.
