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 < 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 }; }; 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 }
