0.56 Inch 7 Segment Led Display 4 Digit Green Color, High Quality 0.56 Module with 7 segment LED display, 4 digits 0.56", blue Kamami on 5pcs SMD 0.56Inch Digital LED Display 7 Segment 1 Grandado 0.56" Inch 4 Digits 7 Segments Digital LED Tube Display HT16K33 I2C IIC 10Pcs 7 Segment 0.56 Inch 4 Digit 12 Pins Red LED Display Module. Feature: This is a basic, 4 digit 7 segment display moduleThe 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. hColor: GreenPackage includes: 5 x Green LED Display Tube ModuleExample1 * 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 bauddisplay. begin(); initializes the displaydisplay. setBacklight(100); set the brightness to 100 %delay(1000); wait 1000 ms }; run loop (forever) void loop() { byte hours = 14; initialize hoursbyte minutes = 39; initialize minutesfor ( ; hours < 24; hours++) { count hours up to 24 for ( ; minutes < 60; minutes++) { count minutes up to 59 display. printTime(hours, minutes, true); display timedelay(60000 clockSpeed); clock delay ms }; minutes = 0; reset minutes }; }; Example2 #include "TM1637. h"; include the TM1637 libraryTM1637 display(2, 3); initialize the library for pins 2, 3void setup(){ display. init(); Start displaydisplay. set(7); Setup brightness 0 to 7int8_t Disp[4]; Dimension of digits }void loop(){ Disp[0] = 1; Write digits to dimensionDisp[1] = 2; Disp[2] = 3; Disp[3] = 4; display. display(Disp); Show dimension(digits) to display } ,,
