read(): 描述:读取传入的串行数据。 函数原型:Serial.read() 参数:无 返回值:可用的传入串行数据的第一个字节(如果没有可用的数据,则为-1) - int print(): 描述:在串行口以人们可以看懂的 ASSCII 码的形式打印数据。 函数原型:Serial.print(val) / Serial.print(val, format) 参数: val:要打印的值。

“DigitalReadSerial”示例的功能是读取数字输入，并将结果输出至串口监视器。其代码结构分为三个主要部分：设置函数、循环函数以及注释与说明。设置函数定义了串口初始化和针脚配置。在Arduino IDE的示例代码中，首先初始化串口通信为9600bps，之后将指定的数字针脚（这里是针脚2）配置为输入模式。这样，Arduino...
