IfStatementConditional:通过for循环来控制多个LED灯 If声明条件:使用一个‘if 声明’,通过改变输入条件来改变输出条件 Switch Case:怎样在非连续的数值里选择。 Switch Case 2:第二个switch-case的例子,展示怎样根据在串口收到的字符来采取不同的行为 While 声明条件:当一个按键被读取,怎样用一个while循环来校准一...
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....

and debugger from arduino says me error, like: 75:1: error: expected unqualified-id before 'switch' Can somebody explain or correct the mistake? And why it happens? May 4, 2015 at 6:41pm Gamer2015(810) your function loop endsd before the switch statement so switch is in no function....
–There is a watchdog timer in the ESP8266 that will reset the processor if you keep it busy too long. More on that in a future posting. Put lots of yield() or delay(0) statement in your program to keep this from happening. Note, delays with values greater than zero (delay(10) ...
