AWESOME project!



This will be a quick explanation of how i built the ping pong scoreboard.

  • 1 x Arduino Nano (I used a cheap imitator from eBay)
  • 2 x Arcade push-buttons (momentary on type) – Something like this, although I found mine on eBay
  • Mounting method for the push-buttons under the table
  • DPST switch (for mode selection)
  • 5V Power supply, fed directly into the matrix power input, the Arduino can get the power from here too, but dont run the matrix from the regulator on the Arduino. These Displays can draw a lot of current.
  • Other miscellaneous wires, strip board, etc.


  1. Connect the centre pin of the mode switch to a digital read pin on the Arduino, and GND and +5V to the other two.
  2. Connect the 3 pins for the matrix to the arduino:
    1. pinCS1
    2. pinWR
    3. pinDATA
  3. Connect the…
