4位元數碼管顯示模組 LED亮度可調 帶時鐘點 TM1637驅動
4位數碼管顯示模塊Arduino LED亮度可調帶時鐘點配件積木
該模塊是一個12腳的帶時鐘點的4位共陽數碼管(0.36英寸)的顯示模塊,驅動芯片為TM1637,只需2根信號線即可使單片機控制4位8段數碼管。
模塊特點如下:
- 顯示器件為4位共陽紅字數碼管
- 數碼管8級灰度可調
- 控制接口電平可為5V或3.3V
- 4個M2螺絲定位孔,便於安裝
控制接口:共4個引腳(GND、VCC、DIO、CLK),GND為地,VCC為供電電源,DIO為數據輸入輸出腳,CLK為時鐘信號腳;
數碼管:4位共陽極的帶比分點的0.36英寸數碼管,紅字高亮;
定位孔:4個M2螺絲定位孔,孔徑為2.2mm,使模塊便於安裝定位,實現模塊間組合;
程序庫例程概覽:
1. ClockDisplay:使用主板上MCU的定時器1來計時,並讓4位數碼管顯示。
2. NumberFlow:0~9,A,b,C,d,E,F等16個字符從右往左流動。
3. StopWatch: 使用主板上MCU的定時器1來計時,可配合按鍵實現秒錶功能。
