帮我写个程序：读取DHT11 温湿度传感器数值，并在LCD 屏幕实时 显示。每间隔5 秒通过串口向电脑发送一次温湿度数据。温度超过设定阈值，小灯1 呼吸；湿度超过阈值，小灯2 呼吸。没超 过是，小灯熄灭,每隔20 秒将温湿度保存到EEPROM 中

以下是一个基于Arduino的程序，可以实现读取DHT11传感器数值，并在LCD屏幕上实时显示。此外，每间隔5秒通过串口向电脑发送一次温湿度数据。如果温度或湿度超过设定阈值，小灯1或小灯2将呼吸，如果没有超过阈值，则小灯将熄灭。每隔20秒，程序还将温湿度保存到EEPROM中。请根据实际情况进行修改。

#include <LiquidCrystal.h>
#include <EEPROM.h>
#include <DHT.h>

#define DHTPIN 2          // DHT11传感器连接到Arduino的2号引脚
#define DHTTYPE DHT11     // DHT11传感器类型
#define LED1 5            // 小灯1连接到Arduino的5号引脚
#define LED2 6            // 小灯2连接到Arduino的6号引脚
#define TEMP_THRESHOLD 25 // 温度阈值
#define HUMIDITY_THRESHOLD 60 // 湿度阈值

DHT dht(DHTPIN, DHTTYPE);
LiquidCrystal lcd(7, 8, 9, 10, 11, 12); //LCD屏幕连接到Arduino的引脚

void setup() {
  Serial.begin(9600);
  dht.begin();

void loop() {
  float temperature = dht.readTemperature();
  float humidity = dht.readHumidity();
  if (isnan(temperature) || isnan(humidity)) {
    Serial.println("Failed to read from DHT sensor!");

  if (temperature > TEMP_THRESHOLD) {
    breathe(LED1);

    digitalWrite(LED1, LOW);
  }

    breathe(LED2);
  } else {
    digitalWrite(LED2, LOW);

  delay(15000);
  saveToEEPROM(temperature, humidity);
}

void breathe(int ledPin) {
  for (int i = 0; i < 255; i++) {
    analogWrite(ledPin, i);
    delay(5);
  }
  for (int i = 255; i >= 0; i--) {
    analogWrite(ledPin, i);
    delay(5);

void saveToEEPROM(float temperature, float humidity) {
  int addr = 0;
  EEPROM.put(addr, temperature);
  addr += sizeof(temperature);
  EEPROM.put(addr, humidity);

  EEPROM.commit();
