Receives from the main serial port, sends to the others. Receives from serial port 1, sends to the main serial (Serial 0). This example works only with boards with more than one serial like Arduino Mega, Due, Zero etc The circuit: * Any serial device attached to Serial port 1 * Seria...

串口事件响应,非必要——serialEvent() 什么是串口 到目前为止,介绍的Arduino API接口都是一些比较底层的接口——即简单的通过电位高低获得指定输入输出的信号。既然这部分系列的文章是介绍Arduino的默认系统API,那么作为嵌入式设备需要提供的几个重要接口之一的——串口协议自然不能不提到。
