[Ed Zarick] continues work on his NBA Hangtime pinball machine with the completion of the scoreboard and backglass. You should remember this project as we already covered the layer audio he developed for the system. Now he’s proving to be a protoboard master, using point-to-point techniques to build a pair of two and a half digit LED displays for team scores, as well as a shot clock timer and other status indicators.
The lighting board that controls it all is commanded via the i2c protocol, just like the three audio modules. It uses shift registers along with MOSFETs and [Ed] has taken the time to add pin headers and sockets for board interconnects. As is true with the audio system, one Arduino Mega acts as the master on the i2c bus and you’ll notice in the video after the break that the display works in perfect harmony with the sound effects.
We can’t wait to see what he comes up with for the play field!

It would be more cool if the playing field was
actually a gym floor or parking lot. Using Wii
strapped to the two players. Pinball games are
sort of a dying breed … so it’s cool to see
someone spend this much time on creating one.
