 ===== Introduction =====
-The game is played on a grid made of LEDs. At the start of the game, some LEDs will blink, indicating the positions of the exit, the key and the mines. The player's job will be to navigate through the grid, collect the key and reach the exit without hitting any bombs.
+The game is played on a grid made of LEDs. At the start of the game, some LEDs will blink, indicating the positions of the mines. The player's job will be to navigate through the grid and reach the exit which will be on the oposite corner, without hitting any bombs.
 The goal of this project was to get myself used to programming an Arduino microcontroller and also to learn how to solder.

 ===== Hardware Design =====
-<note tip>
+List of components:
-Aici puneţi tot ce ţine de hardware design:
+  * Arduino Leonardo
-  * listă de piese
+  * LEDS for the matrix (x36)
-  * scheme electrice (se pot lua şi de pe Internet şi din datasheet-uri, e.g. http://www.captain.at/electronic-atmega16-mmc-schematic.png)
+  * Buttons (x4)
-  * diagrame de semnal
+  * Buzzer
-  * rezultatele simulării
+  * Jumper Cables
-</note>
+Schematic for how the LED matrix is wired together:\\
+{{:pm:prj2022:apredescu:pm_schematic.png?500 |}} \\
+This specific configuration allows the control of the entire matrix using only 7 output pins.
 ===== Software Design =====
+The code was written in Sublime Text 3 and compiled/uploaded to the Adruino using Arduino IDE

+The main loop of the game is:
-Descrierea codului aplicaţiei (firmware):
+  * Showing the player where the bombs are.
-  * mediu de dezvoltare (if any) (e.g. AVR Studio, CodeVisionAVR)
+  * Waiting for input from the joystick (the buttons are connected to analog input pins)
-  * librării şi surse 3rd-party (e.g. Procyon AVRlib)
+  * Moving in the corresponding direction.
-  * algoritmi şi structuri pe care plănuiţi să le implementaţi
+  * Checking if any bombs were hit.
-  * (etapa 3) surse şi funcţii implementate
+      * Reset if a bomb was hit.
-</note>
+  * Checking if the exit has been reached.
+      * Reset if the exit has been reached.
-===== Rezultate Obţinute =====
+I used the "Charlieplexing" algorithm to control which specific LED lights up. It works by setting the 2 output pins corresponding to the desired LED to OUTPUT (one to HIGH and one to LOW) and all the other ones to INPUT.

+===== Conclusions =====
-O arhivă (sau mai multe dacă este cazul) cu fişierele obţinute în urma realizării proiectului: surse, scheme, etc. Un fişier README, un ChangeLog, un script de compilare şi copiere automată pe uC crează întotdeauna o impresie bună ;-).
-Fişierele se încarcă pe wiki folosind facilitatea **Add Images or other files**. Namespace-ul în care se încarcă fişierele este de tipul **:pm:prj20??:c?** sau **:pm:prj20??:c?:nume_student** (dacă este cazul). **Exemplu:** Dumitru Alin, 331CC -> **:pm:prj2009:cc:dumitru_alin**.
+This project has been a great learning experience and very interesting to do despite the fact that I didn't get to implement all of the features I initially planned for it.
