                        Clock example example (Extended class example)

                        Display a clock on the display. For this demo you can add a speed multiplier to make the clock run faster. For a real clock you want to use a delay of 1 min or even use a Real Time Clock module (RTC)

                        The circuit:
                        * connect TM1637 pin CLK to Arduino pin D4
                        * connect TM1637 pin DIO to Arduino pin D5
                        * connect TM1637 pin Vcc to Arduino pin 5V
                        * connect TM1637 pin GND to Arduino pin GND



                        // include the SevenSegmentTM1637 library

                        #include "SevenSegmentTM1637.h"
                        #include "SevenSegmentExtended.h"



                        initialize global TM1637 Display object

                        * The constructor takes two arguments, the number of the clock pin and the digital output pin:
                        * SevenSegmentTM1637(byte pinCLK, byte pinDIO);



                        const byte PIN_CLK = 4; // define CLK pin (any digital pin) const byte PIN_DIO = 5; // define DIO pin (any digital pin)
                        SevenSegmentExtended display(PIN_CLK, PIN_DIO);

                        const unsigned int clockSpeed = 10000; // speed up clock for demo


                        // run setup code

                        void setup() {

                        Serial.begin(9600); // initializes the Serial connection @ 9600 baud
                        display.begin(); // initializes the display
                        display.setBacklight(100); // set the brightness to 100 %
                        delay(1000); // wait 1000 ms



                        // run loop (forever)

                        void loop() {

                        byte hours = 14; // initialize hours
                        byte minutes = 39; // initialize minutes

                        for ( ; hours < 24; hours++) {   // count hours up to 24

                        for ( ; minutes < 60; minutes++) {   // count minutes up to 59

                        display.printTime(hours, minutes, true); // display time
                        delay(60000 / clockSpeed); // clock delay ms

                        minutes = 0; // reset minutes




                        #include "TM1637.h"; // include the TM1637 library
                        TM1637 display(2, 3); // initialize the library for pins 2, 3

                        void setup(){

                        display.init(); // Start display
                        display.set(7); // Setup brightness 0 to 7
                        int8_t Disp[4]; // Dimension of digits


                        void loop(){

                        Disp[0] = 1; // Write digits to dimension
                        Disp[1] = 2;
                        Disp[2] = 3;
                        Disp[3] = 4;
                        display.display(Disp); // Show dimension(digits) to display
