Buzzer button

This project is based on a arduino mega. This project has a maximum of 10 buzzers, but you can play with 1,2...10 buzzers plug anywhere.
The buzzer library can support more buzzers.

Library

• Buzzer.h
• Adafruit_GFX.h
• Adafruit_TFTLCD.h
• TouchScreen.h

Structure

typedef struct Buzzer {
    int pin_button;
    int pin_led;
    int number;
    int team;
    int score;
    bool used;
} Buzzer;

typedef struct Button {
    int x;
    int y;
    int x_size;
    int y_size;
    String string;
    int size_string;
    uint16_t color_string;
    uint16_t color_background;
} Button;

Initialisation / Use of buzzers

Parameters

• first (10) is the maximun of buzzers
• second (false) enable to get teminal display (put true to dev)

Buzzers buzzers(10, false);

Buzzer buzzer[] = {{51, 45, -1, -1, 0, false},
                   {27, 31, -1, -1, 0, false},
                   {29, 25, -1, -1, 0, false},
                   {26, 24, -1, -1, 0, false},
                   {35, 40, -1, -1, 0, false},
                   {37, 32, -1, -1, 0, false},
                   {41, 46, -1, -1, 0, false},
                   {28, 44, -1, -1, 0, false},
                   {30, 42, -1, -1, 0, false},
                   {39, 33, -1, -1, 0, false},
};

Now we can use different fonctions of Buzzer library :

    buzzers.ledOffAllBuzzer(buzzer);

    buzzers.blinkAllBuzzer(buzzer);

    buzzers.displayAllInfosBuzzer(buzzer);

    ...

Initialisation / Use on touch button

#define    BLACK   0x0000
#define    BLUE    0x001F

#define WIDTH_SCREEN 480
#define HEIGHT_SCREEN 320

#define BOXSIZE_X 250
#define BOXSIZE_Y 75

#define CENTER_BOX_X (WIDTH_SCREEN / 2 - BOXSIZE_X / 2)

Button your_button = {CENTER_BOX_X, HEIGHT_SCREEN / 1.5, BOXSIZE_X, BOXSIZE_Y, "Terminer", 3, BLACK, BLUE};

Code to draw a button:

 drawButton(&your_button);

Code to get buttons' state:

 if (touchButton(&your_button)) {
     ...instructions...
 }
