How to create the fischertechnik LED GUESS-O-MATIC GAME:

I play with different educational manipulatives for a living. (Visit www.weirdrichard.com).

An easy-to-build application is the LED GUESS-O-MATIC GAME. The robotic controller (in this case the PCS BRAIN) randomly selects one of two LED to light. The LEDs are hidden behind mounting plates. Next to each LED is a push button. Guess which LED is lit by pressing one of the switches. If your guess is correct, the controller plays a happy tune! Guess incorrectly, and you receive a single beep.

This instructable will describe how to create a fischertechnik LED GUESS-O-MATIC GAME!

Step 1: Gather Elements:

You will need to gather your elements. The fischertechnik elements are available from a range of kits available from ebay, Craig's List, or fischertechnik retailers.

Elements can be purchased individually from www.fischertechnik.com.

The PCS BRAIN kit and electronic components can be purchased here:

The PCS BRAIN kit and electronic components can be purchased in Germany here:

OR the controller and components can be replaced with similar items purchased elsewhere.
