在Arduino IDE上打开串口监视器,并且发送字符 a,b,c,d,e来点亮相应的LED灯,或者其他东西来关闭它们。 图为Fritzing软件绘制。 原理图 样例代码 /* Switch statement with serial input Demonstrates the use of a switch statement. The switch statement allows you to choose from among a set of discrete val...
For the Arduino switch case code, the OR expression is implied by omission of the break statement. If you leave out the break statement, the flow of operation is for execution of the code in the next case statement. This continues until a break statement is encountered. ...
Compile the code, run it and you will see “Tick Occurred” printed to your serial console on the Arduino IDE every second. Comments Here are few pointers about using interrupts in the ESP8266, as well as in any Arduino based system. –Keep your Interrupt Service Routine (ISR) short. ISR...

通过上面的地址下载我们的源码,其中代码在目录的code目录中,通过arduino直接打开code目录的文件夹即可。 3. 烧录代码 通过Arduino IDE打开我们上一步下载好的代码 文件--> 打开 --> 选择源码所在文件夹中.ino后缀的文件 选择开发板 工具--> 开发板 --> ESP8266 --> NodeMcu 1.0 选择端口 工具--> 端...
Run the sketch and let it run for 30 seconds or so. You should never see the “Arduino Rebooted” message again after reboot. Then, comment out the RESETWATCHDOG statement like this: // #define RESETWATCHDOG Now when you run the sketch, if your WatchDog is working, then you should se...
In addition, in Python the definition line of an if/else/elif statement, a for or while loop, a function, or a class is ended by a colon. In MATLAB, the colon is not used to end the line. Consider this code example: Python 1num = 10 2 3if num == 10: 4 print("num is eq...
为了使程序工作,你的开发板需要连接到电脑。在Arduino IDE上打开串口监视器,并且发送字符 a,b,c,d,e来点亮相应的LED灯,或者其他东西来关闭它们。 图为Fritzing软件绘制。 原理图 样例代码 /* Switch statement with serial input Demonstrates the use of a switch statement. The switch ...
switch case statement 与if语句类似,switch...case通过允许程序员指定应在各种条件下执行的不同代码来控制程序流。 特别是,switch语句将变量的值与case语句中指定的值进行比较。 当找到一个case语句,其值与变量的值匹配时,将运行该case语句中的代码。 break关键字使switch语句退出,通常在每个case的末尾使用。 如果...
