the new version
is a bit different (and requires less
It is advised to build the new version (much more fun to play). Hardware
- An Arduino
- A Hitachi HD44780 compatible LCD display (I used 16x2, but 20x4 should work too)
- 2 tilt switches
- A pushbutton
- 3 10K Ohm resistors (pull-up for the tilt switches and the buttons)
- 2 10k Ohm potentimeters (one for spin control and [an optional] one for LCD contrast)
- Optional piezo speaker
See breadboard diagram. Software
The code is here
The maze generation algorithm is the same as Ariadne's (See explanation there
If you connect the piezo speaker, you can mute it by setting MUTESOUND to 1.
Actually - this is the default :)
Why have the speaker and mute it? Glad you asked:
Like I've mentioned, you can also run Ariadne's code
on this box.
Ariadne only beeps when you hit a wall (i.e. you've made a mistake). This can be avoided.
Marble Disorder beeps whenever there's a spin (i.e. when both tilt-switches allow the marble to move to 2 different cells, and the spin potentiometer determines which one).
be avoided - so you end up with a pretty noisy game. It does
help play the game - but I'm not sure it's worth the hassle of all those beeps.
Another option is to put a switch on the piezo speaker (something my Electronic Brick shield doesn't allow).
