Serial.available() 的意思是:返回串口缓冲区中当前剩余的字符个数。一般用这个函数来判断串口的缓冲区有无数据,当Serial.available()>0时,说明串口接收到了数据,可以读取; Serial.read()指从串口的缓冲区取出并读取一个Byte的数据,比如有设备通过串口向Arduino发送数据了,我们就可以用Serial.read()来读取发送的数据。
Read a switch, print the state out to the Arduino Serial Monitor. 读取开关状态,并打印状态到 Arduino串口监视器。 This example shows you how to monitor the state of a switch by establishingserial communicationbetween your Arduino and your computer over USB. 该例展示了如何监控开关的状态,通过 USB ...

第二个,最简单, arduino sensor 的code里不要用Serial.write,用Serial.print,因为Serial.write只可以输出one bit的value 希望帮到你:) 赞 回复 RRRRRRRRRidge (未來不迎 當時不雜 既過不戀) 2014-04-05 00:20:46 对的 用Serial.print,如果用其他sensors要不停输出multiple sensors的话加一行空格, max ...

(以下实例基于Arduino UNO) 1,接收函数Serial.read() intSerial.read(void) 如果串行数据缓冲区有数据,这个函数会读取串行数据缓冲区的第一个字节,数据读取位置移动到下一个数据缓冲区,也就是说如果继续读取的话会读取下一个数据缓冲区的第一个字节.
