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...
The Arduino switch statement takes a single expression. Multiple Arduino case statements act on the expression. Here's the general idea: switch (<expression>) { case 3 : <do action 1>; break; case 4 : <do action 2>; break; default : <do action 3>; }...

在配置好Arduino环境下的ESP8266开发版后,跑了一下Demo却发现编译错误 观察一下,发现是编译器识别不了一些类型、关键字啥的,这就让我很郁闷,难道是编译器太古老了,也不对呀,这个IDE版本比较新,去社区求助一下,结果也没有人能解答的了,看来就我一个人遇到了这种错误,还是得靠自己解决问题呀! 仔细观察一下报错...
IOT ESP8266 Timer Tutorial – Arduino IDE This is the second of a multi-part posting on the ESP8266. We are giving an example of how to use the timers on the ESP8266. It was very hard to find a simple example of how to use the timers under the Arduino IDE. We need this for our...
Lighting Up and LED With a Switch in Arduino: Wassup ladies and gentlemen! This tutorial will teach you how to light up an LED with a switch using Arduino. Firstly, make sure your work environment isn't a mess (like mine). Also, you'll be playing with el
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...
