Arduino IF Statement Code Examples by Lewis Loflin Video for this page: Arduino Comparison IF Operators Think of a micro-controller as a box full of basic logic circuits, gates, etc. To control the "box" we have to tell it what hardware to use. We must tell the "box" how to manipulat...
The Arduino if else statement : Or how the Arduino makes decisions. Learn exactly how to write the "if else" code. Find out the different ways of using it - you don't always need the 'else' part. Find out the short way of writing 'if-else' (less brackets to write). learn about...
Given below is the structure of anifstatement: If (conditional expression) { Body of the if statement } Theconditional expressioncan be anything that can result either in true or false. If the statement is true, the code in the body of the statement is executed. However, if th...

if (expression) statement; 如果你有一个语句,你可以使用没有大括号{}的if语句。 形式2 if (expression) { Block of statements; } 形式3 if … else语句语法 if (expression) { Block of statements; } else { Block of statements; } 2.5 改变程序流程的if条件式 -比较运算符 比较运算符说明 == 如果...
resistor will be disabled. If the pin is set to OUTPUT via pinMode(), you can set the pin to HIGH (5 volts) or LOW (0 volts/GND) via the digitalWrite() statement. If the pin is set to INPUT mode via pinMode(), when you set the pin to HIGH via the digitalWrite() statement,...
// statement block } 1. 2. 3. 例子 for(counter = 2;counter <= 9;counter++) { //statements block will executed 10 times } 1. 2. 3. 4.5.4 嵌套循环 C语言允许你在另一个循环内使用一个循环。下面的例子说明了这个概念。 嵌套循环语句语法 ...
Finally, close up your brackets from theifstatement, while statement, and main loop : 最后,为判断语句、循环语句和主循环敲上封闭的大括号。 Once you have programmed the board, open your Arduino Software (IDE) serial monitor. Make sure you have chosen to send a newline character when sending ...
