                      This is a basic, 4-digit 7-segment display module
                      The display features double points in midle.
                      The decimal point per digit not active.
                      Module connecting to digital I/O on 2 pins.
                      For use library: TM1637.h
                      Color: Green, Red, Yellow (Optional)

                      Package includes:

                      1 x LED Display Tube Module



                      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 pin D4
                      * connect TM1637 pin DIO to pin D5
                      * connect TM1637 pin Vcc to pin 5V
                      * connect TM1637 pin GND to 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
