Sometimes you just want to add a quick numeric display to your projects. This 4-digit 7 segment LED display connects to your arduino using only 2 pins!This module uses a TM1637 LED controller to control the segments.Features4digitred alpha-numeric display with “:”8 adjustable luminance levels3 to 5VDCPinout: GND, Vcc, CLK, DataLED Size: 13x32mmMounting board size: 24x40mmArduino IDE: Library Manager –> Grove 4-Digit DisplayTest Code:#include “TM1637.h”#define CLK 2//pins definitions for TM1637 can be changed to other ports#define DIO 3TM1637 tm1637(CLK, DIO);void setup(){ tm1637.init(); tm1637.set(2);// 0-7 to set brightness}void loop(){ tm1637.point(true); // display the “:” tm1637.display(0, 1); // display in column “0” the number “1” tm1637.display(1, 2); // values can be from 0 – 15 for hexadecimal digits tm1637.display(2, 0); tm1637.display(3, 0); delay(500); tm1637.point(false); tm1637.clearDisplay(); // clear the display delay(500);}
