voidsetup(){ }voidloop(){ myFunction(); }voidmyFunction(){//do something} 有两种解决方案。 首先,你可以在任何调用上方声明该函数。 通常,此声明在文件顶部完成。 C++ // Declare function herevoidmyFunction();voidsetup(){ }voidloop(){ myFunction(); }// And, define the function herevoidmy...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...

function. The analogWrite() function uses PWM, so if you want to change the pin you're using, be sure to use another PWM capable pin. On most Arduino, the PWM pins are identified with a "~" sign, like ~3, ~5, ~6, ~9, ~10 and ~11. ...

You can also declare and initialize an array at the same time: int preinitialized[3] = {1, 2, 3}; Strings Working with Strings in Arduino is different from working with Strings in Processing or openFrameworks because the Arduino language doesn’t use a String class like C++ and Processing...
