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).
<p>Hai </p><p>Is this what you want,I uncheck ' I Made it ' (hand) and than i post a image</p><p>Can you explain the letters R11 and C11 I don't now what it means , sorry</p><p>Kind regards</p>
<p>Hi. Had some time to look at the code, and I have a theory:</p><p>In <a href="https://gist.github.com/thedod/720596#file-ariadne-pde-L184" rel="nofollow">line 184</a> where it says lcd.begin(16,2), it should probably say lcd.begin(20,4) instead.</p><p>If I'm right, you'll get a working game, but only 16x2 characters will be utilized.</p><p>Please let me know if whether it works (perhaps add a photo).</p><p>If it does, I can go over the code and figure out what else to change so that you can view a larger part of the maze.</p>
Thanks. I now understand that the photo is <em>not</em> of a 16x2 display, and that you weren't asking a <em>rhetorical</em> question ?. I somehow &quot;decided&quot; that you had a working game. Sorry about that.<br> <br> This sure looks wrong (compared to the attached image): the compass is above the R and C indicators, Normally R and C are between 0 and 9 (a single digit), it seems like even the fonts have a black picture in the corner (probably fonts are a different size on this display).<br> <br> Anyaway, let me see if by looking at specs alone I can figure out what to change in the code (might take from a few days to a few weeks, depending on work etc.). Maybe I'll sed you some test pde files (that show test patterns on the LCD etc.).<br> Maybe it will be easy enough to work this way. If not - I'll need to order a display like yours and give it a go.<br> <br> Thanks for finding me a new challenge ?
Great post, its my first introduction into the arduino world and thanks to you now I know much more than I did yesterday!!!
<p>Hai,</p><p>I have made de Maze game and its works well , thanks for sharing the code</p><p>Cane a make it for a LCD with 20&times;4 , what must a change in the code , please can you help<br> And place the text on the side</p><p>Kind regards<br><a href="mailto:erwin.meyvaert@telenet.be" rel="nofollow">erwin.meyvaert@telenet.be</a></p>
<p>&gt; I have made de Maze game and its works well</p><p>This is so cool. Could you please take a photo and do an &quot;I made it&quot; comment? Thanks</p><p>&gt; LCD with 20&times;4</p><p>Like <a href="https://www.sparkfun.com/products/256" rel="nofollow">this one</a>? I can try and take a look how different the specs are but in order to be sure, I'll need to actually have one. Maybe next time I'm on an electronics shopping spree :)</p>
<p>Thanks for repeat on my letter</p><p>This is what i all have done</p><p>I made a LCD above mine arduino with lots of sensors , Mic , Pot , LDR , TNC , and a switch , so I can use it with other prog eventual</p><p>Sorry if my englisch is not oke ( dutch)</p><p>Kind regards</p>
<p>This is great. Here's my <a href="https://diasp.de/posts/1284917" rel="nofollow">post</a> about it.</p><p>If possible, please click the &quot;I made it&quot; button and upload an image or 2 there (maybe an angle that shows the potentiometer and button). </p><p>I've only discovered the &quot;I made it&quot; button a few days ago and I'm not sure in what way &quot;I made it&quot; comments are different than regular ones, where they get displayed, etc. The only thing I know is that they need to have at least one photo.</p><p>So if you can, please give &quot;I made it&quot; button a test spin, and let's see what it does :) (don't feel like you <em>have</em> to do it. Entirely up to you)</p><p>All the best,</p><p>The Dod.</p>
