This year at the Trunk O Treat at my church I made the game "Simon Says Narnia". This is the electronic game Simon by Hasbro built into a wooden wardrobe like in the movie The Chronicles of Narnia, "The Lion, the Witch and the Wardrobe" by C.S. Lewis.

Step 1: How the Electronic Simon Game Works

The Simon game lights its colored buttons with 3.5VDC (On State) and 0V (Off State). With this condition a TTL logic device can be used with the Simon game. I connected wires to each color of the (+) side of the small Simon light bulbs. I tied each of these (control +) wires to separate TTL MOSFET Transistors (On Semiconductor TTL Power MOSFET part# MTP10N10EL)to drive higher current load. I need around 300mA@12VDC to illuminate the game pushbutton switches and around 850mA for the LED's in each the picture frame.
