Serial方法是Arduino编程语言中的一个函数,用于与计算机或其他设备进行串行通信。它允许Arduino板与外部设备通过串行通信接口(如USB、UART等)进行数据交换。 Serial方法可以用于以下几个方面: 调试和监控:通过Serial方法,可以在Arduino程序中插入调试信息,以便在开发过程中进行调试和监控。可以使用Serial.print()或Serial.pri...

Then it waits for a byte in the serial port, and sends three ASCII-encoded, comma-separated sensor values, truncated by a linefeed and carriage return, whenever it gets a byte in. 该程序在启动时发送一个 ASCII 大写字母 A(字节值 65),并一直重复直到收到一些数据。然后在串口等待一字节,并...
