Ariadne - a 1st person maze on a 16x2 LCD

This game is a homage to Ariadne, the maze-generator from Inception :)
If you haven't seen the movie yet - watch this video again after you do (you can also watch it now - it's not a spoiler, it's just funnier for inception-vets).



The nice thing about it is that it's a 1st-person game, so when you rotate your character, it stays in place, and the maze rotates around it. This means that you don't only see a narrow strip of reality - you can choose between 4 of them. If you can keep a mental image of all of them, you can cover quite a lot of maze without moving. It's not as hard as it seems. It's quite intuitive.

It's a game I actually enjoy playing. Not too easy and not too hard to solve.
It's easy to build too. Most of it is software.
 

Step 1 Hardware

What you need is:

• An Arduino
• A Hitachi HD44780 compatible LCD.
• A pushbutton on pin 10 (also connected to gnd via a 10K Ohm pull-up resistor).
• A potentiometer on analog pin 1 (outer legs go to +5v and gnd).
• A piezo speaker between pin 9 (PWM) and gnd.

See breadboard diagram.

Since the only LCD I have is an Electronic Brick, I wasn't sure how to wire a "real" LCD. I had an educated guess, but it was still only a guess. In the end, I've managed to find a way to "unbrick" the LCD and check the wiring in practice (see photo).

Great post, its my first introduction into the arduino world and thanks to you now I know much more than I did yesterday!!!
