My project consists of a row of L.E.D.’s on a chip board on my knuckles that light up when i make a fist. The L.E.D.’s are set up in a parallel circuit to ensure that each light receives enough power. The way it lights up is through connecting the two negative wires to complete the…

I created a cup on which LEDs light up on the side corresponding to the liquid level inside the cup using a floating magnetic assembly and a series of reed switches.

The Evil Pig stuffed animal uses brass snaps on its feet to complete the circuit to light the LEDs. The LEDs are connected in series to each other with a resistor and are powered by a 9-volt battery that rests in the belly of the pig. The negative lead to the battery is connected to…
