在Arduino IDE中,从“工具”》“端口”》“COM 3 (Arduino Genuino / UNO)”中选择适当的COM端口。 这时,您的设置已准备好开始编程。 编程 在Arduino编程中,有两个基本函数:Void Setup和Void Loop。完整代码及其解释如下所示: void setup() { //Declare A5Analogpin as input pin ...
Arduino Uno有14个输入/输出引脚(0-13,0为Rx,1为Tx)。 LCD本身占用5个引脚(引脚8-12))、传感器1(引脚7)和键盘7(引脚0-6),这很好,因为我有14个潜在引脚。 所以我下载了一个基本程序来快速测试键盘和调整必要的变量。我想通过串行通信在电脑上显示数字。第1行和第4行正常,第2行和第3行不正常。键盘不可...
大部分玩 Arduino 的朋友,都还是从 UNO板子上开始玩,而这些板子的共性,就是都是用了 DIP(直插)28 脚封转的主芯片。而转为 Nano 的话,其实芯片核心并没有变化,但是封装从 DIP28 改为 TQFP32,兼容版的UNO用的和nano版是同样的芯片,软件方面都不需要变动,程序都是通用的。硬件方面又有什么不同呢?32 – 28...
