	Another approach is install a series of LEDs along the path of the wire every 2 inches and then switch these in sequence using the Arduino and a 74154 multiplexor. The multiplexor takes 4 outputs from pins 10,11,12,13 of Arduino input into its pins 20,21,22,and 23 which turns off multiplexor pins 0 to 15 in sequence.

There are three types colors of satin bean bags, red is filled with light fiberfill, green is filled with half fiber and half beans, the blue bag is filled with beans. The tension on the spring is adjusted so that blue bag trips the switch and the green only trips it when it is thrown really hard.

	The Solar Cell Photon Toss is a desktop interactive exhibit that is good for younger audiences or families. The poster graphic is mounted on a rigid board with a hole at the center at the junction layer. Behind the hole is a hinged panel and a microswitch which connects to strips of LED lights which flash when the circuit is completed. The switch is adjusted so that it requires the force of the heavy blue bag in order to actuate.
