The first parameter (where you see ’11’) in this PWM code sample just specifies the pin number you’re controlling, as is the case with the previous example. Play around with this and adjust the values, as well as observe the voltage across the LED’s pins while you’re doing it. ...

LED_BUILTIN：是一个宏，全称：LED-BUILT-IN，内嵌LED的意思，在Arduino的核心库文件“pins_arduino.h”中已经定义，它代表13，一般为了板子兼容写法就这么写，如果写2或者其他引脚数值可能程序代码的移植性没那么好，所以推荐：LED_BUILTINpins_arduino.sh 位置：Arduino_Setup_Home\hardware\arduino\avr...
