 ===== 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.

 This specific configuration allows the control of the entire matrix using only 7 output pins.

+The code was written in Sublime Text 3 and compiled/uploaded to the Adruino using Arduino IDE
-===== Software Design =====
+The main loop of the game is:
+  * Showing the player where the bombs are.
+  * Waiting for input from the joystick (the buttons are connected to analog input pins)
+  * Moving in the corresponding direction.
+  * Checking if any bombs were hit.
+      * Reset if a bomb was hit.
+  * Checking if the exit has been reached.
+      * Reset if the exit has been reached.
+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 =====
+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.
