Note the code above. An "if" statement has the general form of: 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 comp...
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...
It returns the result of the <true expression statement> if the condition is true and vice versa.The reason you may want to use it, other than to write very unreadable code is to make code more compact.Here is an example of generating different message output depending on a variable. ...
Category:evive Arduino IDE,Tutorial Introduction Conditional statements check whether a programmer-specified Boolean condition is true or false. They make it possible to test a variable against a value/compare a variable with another variable and make the program act in one way if the c...
The if...else allows greater control over the flow of code than the basic if statement, by allowing multiple tests to be grouped. An else clause (if at all exists) will be executed if the condition in the if statement results in false. The else can proceed another if test, so that ...
code execution “if” construct to make a single choice “if – else” construct to choose either/or if ( something is true ) { code block } if ( something is true ) { code block 1 } else { code block 2 } See http://arduino.cc/en/Reference/If http://arduino.cc/en/Reference/...
voidloop(){if(condition){your code;}} Nel codice precedente, la condizione è booleana. Se la condizione è vera, verrà eseguito il codice all’interno dell’istruzioneif; altrimenti no. Ora come possiamo passare le condizioni nell’istruzioneifutilizzando gli operatori di confronto? Gli ope...

在until循环中,当条件condition不满足时,会一直执行循环中的命令,直到条件满足时跳出循环。 这两种循环命令可以用于if分支之外的循环需求,例如需要在某个条件满足之前一直执行某个命令或一系列命令。 推荐的腾讯云相关产品和产品介绍链接地址如下: 腾讯云服务器(CVM):提供弹性计算能力,支持多种操作系统,适用于各类应用场景...
