Feature:

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 Arduino use library: TM1637.h
Color: Green, Red, Yellow (Optional)

Package includes:

1 x LED Display Tube Module

	Example1

	/*

	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 &lt; 24; hours++) {   // count hours up to 24

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

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

	};
	minutes = 0; // reset minutes

	};

	};

	Example2

	#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

	}
