Cool Creative Switch

This is basically and NOT gate and the coins allow one LED to light up and the other to turn off.

You will need:

2 LED 3 1k resistors 1 10k resistor some sort of power supply within the range of 4V to 6V DC 1 npn transistor (PN2222) 9 wires 2 wires with alliagtoer clips at the end. 2 coins (I used nickels)
