Arduinball! Love your trashcan and be loved in return! First (and last) version of a project so silly it can hurt you: unleash the happiness of your trashcan for a work well done!

Each time you score - throwing a wadded-up ball of paper, a shoe, a cat or whatever you like - your trashcan will be so proud of you! (more proud than your own mother ever was, anyway)

Beware that this is just a draft, and not a mature project. Also, beware that it will make you look very stupid in any respectable circle.


Minimum requirements are a buzzer, a servo, an LED, a button and an infrared proximity sensor (plus cables and some resistors). Oh, an Arduino UNO will help. :-P

The arduinball.fzz file contains the Fritzing circuit diagram; for the proximity sensor I've used a Sharp GP2Y0A02YK0F; you may use whatever you have, but you'll probably need to fix some values in the code.


Just copy the arduinball directory into your ~/sketchbook directory. Most of it is commented, if you can understand my English.


In the media directory, you'll find some picture that may help you building the project (no, really: you're doing it for real?) and a short video (sorry for the abysmally low quality of the audio). Also, the backboard.png and backboard.svg (Inkscape format) files can be used to create the backboard.

How it works

  • copy the arduinball directory into your ~/sketchbook directory
  • it needs the Arduino RRD library, which can be found here:
  • build the backboard and install the various pieces as you wish (I've put a small paper heart on the stick rotated by the servo; inside it, there a red LED).
  • upload the program to your Arduino UNO board.
  • throw something into your trashcan.
  • prepare to be loved!
