TIP: Factor code for the compiler to process chains of Arduino if else code.For example the trivial code above could be re-written as: static int command=0; void d_action(void) { Serial.println("data"); command = 1; } void b_action(void) { Serial.println("begin"); command = 2;...
Learn the fundamentals of conditional statements in programming including if, if-else, and if-else-if statements. Understand how these statements can be used to make your program very powerful and be able to be used for a vast variety of purposes.
// 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Arduino上)。 硬件要求 Arduin...

二、消除if...else的锦囊妙计 1、使用注解 代码中之所以要用code判断使用哪个支付类，是因为code和支付类没有一个绑定关系，如果绑定关系存在了，就可以不用判断了。我们先定义一个注解。less 代码解读复制代码@Retention(RetentionPolicy.RUNTIME) @Target(ElementType.TYPE) public@interfacePayCode { Stringvalue...
The Arduino compiler defines "true" as the word "true", the number 1, or any non-zero number. The compiler defines "false" with the word "false" or the number 0. The code above calls function S1(). If the switch on DP2 is open it returns 0 or false - thus "else" is executed...

Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine. - MarlinFirmware/Marlin
