#include <Keypad.h> 此行导入键盘库,它提供将键盘与 Arduino 连接的功能,但在将其包含在代码本身之前,您需要在 Arduino IDE 中安装该库 转到sketch>include library > manage libraries 在搜索框中输入“键盘”,然后查找 Mark Stanley、Alexander Brevig 的键盘。单击那里的安装按钮。 const byte ROWS = 4; //...
字节colPins[COLS] = {5, 6, 7} 的行引脚;//连接到键盘的列引脚 Keypad customKeypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS); //初始化类NewKeypad的一个实例 void setup() { myservo.attach(9); 伺服关闭(); lcd.begin(16, 2); lcd.print("Arduino 门"); lcd.setCursor(0, 1)...
现在,打开Arduino IDE并选择Sketch ->Include Librarey -> Add .ZIP library。浏览器窗口将打开,导航到ZIP文件,然后单击“确定”。如果成功,您应该注意到Arduino左下角的“库已添加到您的库中”。 现在,您可以在Arduino IDE中使用以下代码,并将其上传到Arduino UNO,以便触摸屏计算器正常工作。再往下,我将代码解释...
