将多个LED以“共阳”接法连接起来,再将多组“共阳”层叠起来,每层负极相连,组成一座灯塔,电路原理类似于LED点阵,各层的正极与负极分别连接Arduino UNO的I/O 端口,见图1: 图中R1——R5为限流电阻,Arduino UNO 各端口可以输出20mA 电流,为确保LED的使用寿命,中间串联100——330欧姆的电阻,五个LED的正极端与A
Arduino/Genuino Uno has a number of facilities for communicating with a computer, another Arduino/Genuino board, or other microcontrollers. The ATmega328 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An ATmega16U2 on the board channels...

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...
