利用Arduino实现数码管显示功能物联网

@Tinbur物联网
利用Arduino实现数码管显示功能 1.实现功能的代码 1.1数码管显示滚动自定义字符串

#include SevenSegmentTM1637display(5,4); void setup(){ display.begin(); }void loop(){ display.setBacklight(50); display.print("123456"); }

1.2数码管显示自定义的时间

#include #include SevenSegmentExtendeddisplay(5,4); void setup(){ display.begin(); display.setBacklight(20); }void loop(){ display.printTime(12,30,HIGH); }
