要写入串行线,我们使用Serial.println()函数。您只需用引号将要打印的文本写上并放在Serial.println()的括号中。 将此草图上传到Arduino Uno开发板时,启动Serial Monitor工具。写“ 1”并发送。而且,现在您正在与Arduino Uno通信:) 现在,让我们使用上一个示例中的按钮。让我们读取数字输入引脚的状态,然后将其发送到...

Serial.println("Enter LED Number 0 to 7 or 'x' to clear"); } 首先,我们增加命令行'Serial.begin(9600)'。这样就可以开始串行通信,这样Arduino就可以通过USB连接发送命令了。值9600称为连接的“波特率”。这是数据发送的速度。您可以将此值更改为更高的值,但是您还必须将Arduio串行监视器更改为相同的值。
