单片机流水灯程序
单片机流水灯程序流水灯是一种简单而常见的电子技术实验项目，也是学习掌握单片机编程的基本操作之一。
本文将介绍如何使用C语言编写单片机流水灯程序，并通过Markdown文本格式输出。
硬件准备在开始编写流水灯程序之前，我们需要准备以下硬件设备：1.单片机开发板（如：Arduino、STM32等）2.LED灯（可根据自己的需求选择，一般使用红色、黄色、绿色等常见颜色的LED灯即可）3.杜邦线（用于连接单片机和LED灯）程序编写引入头文件首先，我们需要引入相应的头文件，以便使用单片机相关的功能库和定义常量。
#include <Arduino.h>定义引脚接下来，我们需要定义引脚，将LED灯的接口与开发板的引脚连接起来。
#define LED_PIN_1 2#define LED_PIN_2 3#define LED_PIN_3 4#define DELAY_TIME 500在这个例子中，我们使用了3个LED灯，分别连接到开发板的2、3、4号引脚。
DELAY_TIME用于控制每个灯亮起的时间间隔，单位是毫秒。
初始化引脚在进入主程序之前，我们需要对引脚进行初始化，设置引脚的输出模式。
void setup() {pinMode(LED_PIN_1, OUTPUT);pinMode(LED_PIN_2, OUTPUT);pinMode(LED_PIN_3, OUTPUT);}主程序接下来就是我们的主程序部分，我们可以使用循环语句来实现LED灯的流水效果。
void loop() {digitalWrite(LED_PIN_1, HIGH);delay(DELAY_TIME);digitalWrite(LED_PIN_1, LOW);digitalWrite(LED_PIN_2, HIGH);delay(DELAY_TIME);digitalWrite(LED_PIN_2, LOW);digitalWrite(LED_PIN_3, HIGH);delay(DELAY_TIME);digitalWrite(LED_PIN_3, LOW);}在这个例子中，我们依次点亮每个LED灯，并延迟一定的时间后熄灭，然后依次点亮下一个LED灯，以此循环。
