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。
value:type of pulse to read: either HIGH or LOW. (int) timeout (optional):the number of microseconds to wait for the pulse to start; default is one second (unsigned long) 实验程序: const byte trigPin = 10; const int echoPin = 9; ...
The Arduino IDE (described in Recipe 1.3) provides a Serial Monitor (shown in Figure 4-1) to display serial data sent from Arduino. Figure 4-1. Arduino Serial Monitor screen You can also send data from the Serial Monitor to Arduino by entering text in the text box to the left of the...
