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!
Note: The images were generated by a CAD program and a fischertechnik elements library.
Step 1: Gather Elements:
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.
The Parts List:
2 Hinged Block Tab (#31426)
2 Hinged Block Claw (#31436)
4 Building Block 15 with Counterbore (#32321)
8 Building Block 30 (#32879)
2 Building Block 15 (#32881)
2 Building Block 15 with 2 Pins (#32882)
1 Base Plate 120x60 (#35129)
6 Mounting Plate 15x45 (#38242)
1 PCS BRAIN
4 Sensor Cables
2 LED Elements
4 Sensor Cables
2 Switch Elements
(A small screwdriver is useful to attach LED and TOUCH SENSORS to the Building Block 15s with Counterbores)
Step 2: Add LEDs to Base
Step 3: Create LED Covers
Step 4: Add Touch Sensors
Step 5: Connect LED Guess-O-Matic to the BRAIN
Step 6: Program the Game
I took screen captures so that the program can be replicated.
Step 7: Play the Game!
Run the program on the BRAIN by hitting the Start/Run button. Select the LED that is lit and hit the appropriate Touch Sensor. If your guess is correct, you will hear a happy tune. If it is incorrect, you will hear a single beep.
