【实验一】实现滚动显示自定义字符串。
【实验二】实现显示自定义时间。
【实验三】实现显示秒表。

二、实验软硬件环境
硬件：Arduino、TM1637数码管
软件：Mixly IDE

三、实验代码
【实验一】实现滚动显示自定义字符串。

#include <SevenSegmentTM1637.h>

SevenSegmentTM1637  display(4,9);

void setup(){
   display.begin();
  display.setBacklight(20);
}

void loop(){
  display.print("136a");

}

【实验二】实现显示自定义时间。

#include <SevenSegmentExtended.h>
#include <SevenSegmentTM1637.h>

SevenSegmentExtended  display(4,9);

void setup(){
   display.begin();
  display.setBacklight(20);
}

void loop(){
  display.printTime(12,30,HIGH);

}

【实验三】实现显示秒表。
