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...
if (boolean expression) { statement(s) } else if (boolean expression) { statement(s) } else { statement(s) } 3.3 //(单行注释) Comments(注释) 注释用于提醒自己或他人程序是如何工作的。它们会被编译器忽略掉,也不会传送给处理器,不会执行,所以它们在Atmega芯片上不占用体积。 注释的唯一作用就是使...
When using anifstatement, the code in its body runsonlywhen the if statement evaluates to true. If it evaluates to false, program execution skips the code in the body of the if statement and goes to the statement the body of theifstatement. ...

the same as the assignment operator =, and the double equal sign is an operation used in the expression of the if statement to determine whether the expression can be true. The single equal sign is used to assign a value to a variable.在本段程序中也涉及到了if~else这个语句，下面来介绍if...
