现在复制下面的代码并将其粘贴到IDE中。将其上传到arduino。 (可以从下面下载4x3的代码):- 此代码将帮助您检查键盘的工作情况,它显示在串行监视器上按下的按钮。 /*Code for 4x4 keypad*/ #include const byte ROWS = 4; const byte COLS = 4; char keys[ROWS][COLS] =
如本教程前面所述,Arduino社区具有一个名为LiquidCrystal的库,该库使对LCD模块的编程变得不那么困难。您可以在Arduino的官方网站上探索有关该库的更多信息。 // include the library code:#include<LiquidCrystal.h> 接下来,我们必须创建一个LiquidCrystal对象。该对象使用6个参数,并指定将哪些Arduino引脚连接到LCD的RS...
Using an LCD is one of the ways to output information in Arduino projects. The main drawback about an LCD is that it occupies too many pins on your Arduino board. But there are some serial implementations such as here. So I got one. ...
