Working on speed test game
First power on test of matrix display for speed game results display. It works.
The final outcome will be something along the lines of http://petenpaja.blogspot.se/2013/04/first-project-arduino-spede.html but with matrix display to display more information while waiting for new player.
The finalized product can be seen at Kaboom Science exhibitions and workshops but you will have to wait for it. Hopefully there will also be more detailed description of the project later on.
