esp8266天气时钟arduino代码

以下是使用ESP8266制作天气时钟的Arduino代码示例：

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266HTTPClient.h>
#include <ArduinoJson.h>
#include <Time.h>
#include <TimeLib.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

// Replace with your network credentials
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";

// Replace with your city and API key
const char* city = "your_city";
const char* apiKey = "your_API_key";

// OLED display
#define OLED_RESET 0
Adafruit_SSD1306 display(OLED_RESET);

void setup() {
  Serial.begin(115200);
  delay(1000);

  // OLED display setup
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  display.clearDisplay();
  display.setTextSize(1);
  display.setTextColor(WHITE);
  display.setCursor(0,0);
  display.println("Weather Clock");
  display.display();
  delay(2000);
  display.clearDisplay();

  // Connect to Wi-Fi
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi!");

  // Initialize time
  configTime(0, 0, "pool.ntp.org");
  while (!time(nullptr)) {
    delay(1000);
    Serial.println("Fetching NTP time...");
  }
  Serial.println("NTP time fetched!");
}

void loop() {
  // Connect to OpenWeatherMap API
  HTTPClient http;
  String apiUrl = "http://api.openweathermap.org/data/2.5/weather?q=" + String(city) + "&appid=" + String(apiKey);
  http.begin(apiUrl);
  int httpCode = http.GET();
  if (httpCode > 0) {
    String response = http.getString();
    // Parse JSON response
    DynamicJsonDocument doc(1024);
    deserializeJson(doc, response);
    JsonObject weather = doc["weather"][0];
    JsonObject main = doc["main"];
    String description = weather["description"];
    float temperature = main["temp"];
    int humidity = main["humidity"];
    // Display data on OLED display
    display.clearDisplay();
    display.setCursor(0,0);
    display.println("City: " + String(city));
    display.println("Date: " + String(day()) + "/" + String(month()) + "/" + String(year()));
    display.println("Time: " + String(hour()) + ":" + String(minute()) + ":" + String(second()));
    display.println("Temperature: " + String(temperature) + " C");
    display.println("Humidity: " + String(humidity) + " %");
    display.println("Description: " + description);
    display.display();
  }
  else {
    Serial.println("Error connecting to OpenWeatherMap API!");
  }
  http.end();

  // Wait for 1 minute before updating data
  delay(60000);
}

请注意，您需要将代码中的以下部分替换为您自己的网络凭据和OpenWeatherMap API密钥：

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const char* city = "your_city";
const char* apiKey = "your_API_key";

此外，您还需要将Adafruit_SSD1306库和ArduinoJson库添加到您的Arduino IDE中。
