Picture of Das Blinken Bonken! An arduino ball throwing game platform.
This is a fun and pretty easy project that I built as a Christmas present for my son who loves throwing things. Watch the video to see what it can do.

It's built out of a regular Arduino UNO, pressure sensors made from velostat, and RGB LED strip, and 7 segment LED display.

Source code for the games is available on github.


Step 1: Gather Materials

Materials List:
  • 2'x2' sheet of 1/4 inch luan for the target segments
  • 2'x2' sheet of 3/4 inch faced plywood as a backing board.
  • a sheet of Pressure-Sensitive Conductive Sheet (Velostat/Linqstat) for the pressure sensors (http://www.adafruit.com/products/1361)
  • any old 5v arduino of your choosing (I used an uno)
  • a big 7 segment display (http://www.adafruit.com/products/1269)
  • a strip of 24 individually addressable RGB LEDs (http://www.adafruit.com/products/1461)
  • some solid core wire
  • 4 1K resistors
  • some thin foam or thick cloth to act as a shock absorber. (1/8" foam used in construction to separate 2by material from concrete available at any building supply works great)
  • fine metal mesh (like from a screen door, though should be metal, not plastic)
  • scotch tape
  • small brass screws and washers for attaching the target to the backer board
  • Female headers to make connectors to plug into the Arduino and the 7 segment LED display. (http://www.adafruit.com/products/598)
  • 2 power supplies, one for the Arduino (9 or 12v) and one 5volt for the LED strip. (The arduino 5v vcc doesn't provide enough current for the LED strip).
  • Section of 2x2 pine or other wood for legs of the backer
  • Jigsaw for cutting out curves in the target backer board
  • Pull saw or other fine saw for cutting the target pieces
  • Hole-saw for cutting the center target piece
  • Hand saw or circular saw for cutting the backer board
  • Sand-paper or orbital sander
  • soldering iron
  • hot-glue gun
  • drill with various sized bits
  • Razor blade or utility knife and scissors for cutting foam shock absorber


lets gonna play, i like to through things too!

EXCELLENT! I will do this with my class. Your son did a great job presenting as well.

Thanks! It was all on the first take too! I look forward to seeing your version and any mods you come up with.

Nicely Done !!!!
Thanks For Sharing !!!!
Only suggestion would be, to set a push-button in parallel with the "Back" and "Forward" ("Reset") Sensors at the top or sides of the board to make it easier to reset and change games (Specially if it is intended to be used by kids!)

Yah, that's not a bad idea. At one point I had it mounted high on the wall, so then it was even harder because you had to be tall to reach the top two pads...

Would it be difficult to add audio (or musical) responses for correct hits/misses, etc?

zippy314 (author)  eleones1 year ago

My original intention was to add a Wave Shield (http://learn.adafruit.com/adafruit-wave-shield-audio-shield-for-arduino) to the project for that purpose, but I didn't get around it. So it's not hard, just more to do...

wow, this is incredible. amazing work.

This is a fantastic project. Thanks a lot for sharing it!

This is awesome! Nicely done, I could throw balls at that for hours!

I live in Poland, write where you live, if shipping does not kill my wallet, I will cut off those parts and send them to you by mail, I need only the dimensions and where the holes are.

i've got plenty laing round so that why i have thought of it
zippy314 (author)  Quadrat1 year ago
Where do you get it?
Quadrat1 year ago
Awesome project. my suggestion if i may would be:using sandpaper plexi panels instead of the plywood, that way the whole panel would lite up for better visual effect.
but anyway it is great idea for kids and adults to have some workout.

Yah, that's a great idea. I did think of that, just didn't have any at hand.
