<condition> ? <statement that executes on true> : <statement that executes on false>;It works in exactly the same way as the if-else statement but the only difference is that both the false part and the true part must be present. It returns the result of the <true expression statement...
if语句是Arduino编程中的一种条件控制结构,用于根据某个条件的真假来执行不同的代码块。其基本语法如下: 代码语言:txt 复制 if (condition) { // 如果条件为真,执行这里的代码 } else { // 如果条件为假,执行这里的代码 } 常见问题及解决方法 1. 条件表达式错误 ...
if (someCondition) { // do stuff if the condition is true } else if (anotherCondition) { // do stuff only if the first condition is false // and the second condition is true } 你任何时候都可以用到if声明。下面的例子如果模拟输入引脚读取的值超过阈值,就会打开pin13的LED灯(内置在很多Ardui...
and if-else-if statement. These statements make it possible to test a variable against a value or compare a variable with another variable, and make the program act in one way if the condition is met, and another if it isn’t. With these conditional statements, the program can...
if (condition) light_led1; else turn_off_led1; The "else" part is optional. "Condition" is boolean term using "true" or "false" A "true" condition lights LED1, a "false" condition turns LED1 OFF. The Arduino compiler defines "true" as the word "true", the number 1, or any ...
Python 编程中 while 语句用于循环执行程序,即在某条件下,循环执行某段程序,以处理需要重复处理的相同任务。当然也可以遍历所有的字符串,列表,元祖等。...其基本形式为: while 判断条件: 执行语句……执行语句可以是单个语句或语句块。判断条件可以是任何表达式
