/* Example code for TM1637 4 digit 7 segment display with Arduino. More info: www.www.makerguides.com */

// Include the library:
#include <TM1637Display.h>

// Define the connections pins:
#define CLK 2
#define DIO 3
const int BUTTON_PIN = 8;
// Create display object of type TM1637Display:
TM1637Display display_1 = TM1637Display(5, 4);
TM1637Display display_2 = TM1637Display(2, 3);
TM1637Display display_v = TM1637Display(7, 6);

// Create array that turns all segments on:
const uint8_t data[] = {0xff, 0xff, 0xff, 0xff};

// Create array that turns all segments off:
const uint8_t blank[] = {0x00, 0x00, 0x00, 0x00};

// You can set the individual segments per digit to spell words or create other symbols:
