Asteroid Shooter :-

We developed it for ArduGem GC'24(IIT Bhubaneswar's inter-branch competition).

Description:-

• This project is based on the concept of Arcade style survival games.
• It is a game of pace, accuracy and reflexes.
• This game is written such that it works even on the lowest end Hardware(Arduino UNO).
• The game's design and the fast paced nature makes it immersive and engaging.

Dependecies:-

• <SPI.h>
• <Adafruit_GFX.h>
• <Adafruit_ST7735.h>
• <EEPROM.h>

Control Scheme:-

• The game starts with a startup screen having it's Name and Highscore of the game.
• Press 'F' to start the game.
• Pressing 'E' will take you to the rules page.
• Asteroids will be spawning randomly from different directions in the game and the player shall aim and shoot the asteroids to destroy them.
• Use the joystick to start aiming at the spawning asteroids.
• Press 'B' to shoot the asteroid.
• Only ONE asteroid can be shot down at a time.
• The player has to shoot down the asteroids in order to survive,there is an aim assist to indicate the direction of fire.
• When the player runs out of ammo, press the button 'B' on the Joystick Shield to reload.
• The player turns Red in order to indicate the reloading sequence.

Powerups:-

• Press 'A' to use Scatter Shot which shoots in all possible directions.
• Every 25 seconds the player can see a blue little circle on the left corner,which indicates SCATTER SHOT.
• Press 'D' to activate SHIELD.
• Every 20 seconds the player can see a little cyan circle on the left corner above the blue circle which indicates SHIELD
• The SHIELD lasts for 5 seconds which makes the player invincible.

Implementation of High Score:-

• The high score data is being held in EEPROM(Electrically Erasable Programmable Read-Only Memory).
• This requies the dependency <EEPROM.h>
• This allows us for the high score to be maintained on the device even if the power is lost as the data is being returned to the EEPROM.

Circuit and it's Components:-

Arduino UNO:-

• It is the brains of the operation.
• We will mainly be using SPI protocol to communicate with the display.
• The Arduino's digital pins 2 to 7 are being used for the push button switches.
• The analog pin A0 and A1 will be taking input from the joystick using Arduino's 10 bit ADC.
• The Arduino is being powered through the USB-A port.

ST7735 TFT LCD Display:-

• This display uses SPI protocol.
• <Adafruit_GFX.h> <Adafruit_ST7735.h> <SPI.h> These are the three dependecies used for the display.

Joystick Shield:-

• The Joystick Shield consists majorly of two parts:- joystick module and push buttons.
• The joystick module gives two analog value pertaining to both the axes through which we can understand the direction joystick is being pointed to.
• The joystick switch button(The button which activates when you press the joystick) is not being used as the Joystick Shield connects that button to digital pin 8 but it is being used for the SPI protocol for the display.

Push button switches:-

• There are six push button switches labeled from 'A' to 'F'.
• The joystick module uses pull up resistors to pull the switches to a logical HIGH.
• When the switches are activated, they are connected to the ground to pull it to logical LOW.
