// 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pin1
How to use if Statement with Arduino. Learn if example code, reference, definition. The if statement checks for a condition and executes the proceeding statement or set of statements if the condition is 'true'. What is Arduino if.
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...
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...
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...
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. ...
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/...
我正在为一个 arduino 项目编码,我遇到了这个问题,谁能帮帮我! if(condition1){ //my codes here } if(condition2){ //my codes here } if(condition3){ //my codes here } ... if(condition100){ //my codes here } else{ my codes here } Run Code Online (Sandbox Code Playgroud) 我想检...
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...
