I play with different educational manipulatives for a living. (Visit www.weirdrichard.com).
An easy-to-build application is the LED REACTION TIME GAME. The robotic controller (in this case the PCS BRAIN) beeps and lights up the first LED as a warning and after a random amount of time will light the second LED. As soon as the second LED is lit, the player will tap the push button sensor. The software will display the amount of time it takes to respond to the light!
This instructable will describe how to create a fischertechnik LED REACTION TIME 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 a variety of sources including www.fischertechnik.de.
The PCS BRAIN and electronic components can be purchased here:
The PCS BRAIN kit can be purchased in Germany here:
OR similar robotic controllers and components can be purchased elsewhere.
The Parts List:
2 LED elements
3 Small Nuts
3 Sensor Leashes
1 Angular Block 60 Degrees
3 Building Block 15 with Counterbore
2 Building Block 30
3 Building Block 15
1 Base Plate 120x60
1 PCS BRAIN
Step 2: Blocks on the Base Plate
Step 3: Touch Sensor
Step 4: Blocks on the Base Plate
Step 5: LED Assembly
In order, connect a Building Block 15, LED assembly, Building Block 30, and LED assembly.
Step 6: Add LED Assembly
Your LED REACTION TIME GAME is finished! All that is left is to program the game and play!
Step 7: Plug in, Program, and Play
I took screen captures so that the program can be replicated.
Download your program, and hook up the LEDs and Touch Sensor to the appropriate ports!
