 While the game is being played, the theme song from Formula 1 will play in the background.

   * Role: To turn off the coresponding led. Each led will have a coresponding button.
   * Each player will have 3 buttons. Normally, a button should use one pin, but this will consume a lot of pins of the board. My solution is to connect 3 buttons on one pin and read the values using adc for determined which button is being pressed.
-  * For this part I need to create a voltage divider. Each button will have his own resistance.

+I will need a pull-down resistor for the input to read 0 when no button is being pressed.
+For pins I will use 2 analog pins (PC0 for player 1 and PC1 for player 2).

+The element that is new to this game is the multiplayer mode. Initially the game was a training method for the formula 1 drivers and of course was singleplayer. Because it will be a multiplayer game, will be fun to play with friends and train your reflexes.
+<note tip>
+For this project, I am gonna use things that I learned from this laboraties:
+  * **Laboratory 0: GPIO**: for leds
+  * **Laboratory 1: UART**: for comunicating with the players (asking their names and send the statistics for each player at the end of the game)
+  * **Laboratory 2: Interupts, Timers**: for implementing debounce and external interupts for buttons. In addition, implementing timers for counting the seconds.
+  * **Laboratory 3: PWM**: for the buzzer to sing the formula 1 theme song
+  * **Laboratory 4: ADC**: for the buttons for each player (along with an interupt) and for the potentiometer
+  * **Laboratory 6: I2C**: for showing information about the score, time on the lcd

+The structure of my project is:
+<code>
+Project
+| - i2c.c
+| - i2c.h
+| - adc.c
+| - adc.h
+| - timers.c
+| - timers.h
+| - usart.c
+| - usart.h
+| - utils.c
+| - utils.h
+| - main.c
+</code>
+I choose this structure for organizing (each protocol and feature will have a file). This is easier for me to read the code and debug.

+<note tip>
+For this project I am gonna use:
+  * **A state machine**: I am gonna have 3 states (start of the game, middle of the game, end of the game). I will use this concept for dividing my code into 3 parts (I will have interupts that need to be working just in one state of the game).
+  * No external library
+</note>
+<note>
+Algorithms and data structures used:
+  * **States of the game**: this is an enum
+  * **UART Protocol**: For finding out the name of the players (and send it to the lcd) and comunicating their average time for the game
+  * **I2C Protocol**: For showing the score, time, names on the lcd
