This is the setup routine, it runs only once, every time the Arduino is started up. (void is a data type, it means no information is returned by the setup, more on this later. The two brackets are used in every function, to pass data through; setup doesn't need any data, so the...

2. 串行通讯接口的封装类库 (15)readBytes() 功能:读输入的串口字符到缓冲区。若确定长度的数据读取完毕或超时 则结束。Serial. readBytes继承了流实用程序类。 语法格式:Serial.readBytes(buffer, length)。 参数说明:buffer:存入数据的缓冲区(char[] 或byte[]型);length: 读取的字节数。
