Write me a arduino script that use open-meteo.com api to get the current weather
To create an Arduino script that uses the Open-Meteo API to get the current weather, you’ll primarily need an Arduino board with internet connectivity, such as the ESP8266 or ESP32. Below is a simple example using the ESP8266. Ensure you have the necessary libraries installed, such as `ESP8266WiFi` and `WiFiClient`.
### Arduino Script
```cpp
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
const char* ssid = "your_SSID"; // Replace with your WiFi SSID
const char* password = "your_PASSWORD"; // Replace with your WiFi Password
const char* host = "api.open-meteo.com";
const char* endpoint = "/weather?latitude=35.6895&longitude=139.6917¤t_weather=true"; // Example for Tokyo, Japan
const int httpPort = 80;
void setup() {
Serial.begin(115200);
delay(10);
// Connect to Wi-Fi
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
// Wait for connection
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
// Fetch weather data
fetchWeatherData();
}
void loop() {
// Your main code can go here
delay(60000); // Delay to avoid frequent requests; change as needed
}
void fetchWeatherData() {
Serial.println("Connecting to Open-Meteo API...");
WiFiClient client;
// Use Wi-Fi Client to connect to the HTTP server
if (!client.connect(host, httpPort)) {
Serial.println("Connection failed");
return;
}
// Prepare the request
String url = String(endpoint);
Serial.print("Requesting URL: ");
Serial.println(url);
client.print(String("GET ") + url + " HTTP/1.1\r\n" +
"Host: " + host + "\r\n" +
"Connection: close\r\n\r\n");
// Read all the response from the server
while (client.connected() || client.available()) {
if (client.available()) {
String line = client.readStringUntil('\n');
Serial.println(line);
// If the line is empty, the header is complete
if (line.length() == 0) {
break;
}
}
}
Serial.println("Closing connection");
}
```
### Instructions:
1. Replace `your_SSID` and `your_PASSWORD` with your Wi-Fi credentials.
2. Adjust the latitude and longitude in the endpoint string to get the weather for your desired location.
3. Upload this script to your ESP8266 or ESP32 board.
4. Open the Serial Monitor (make sure to set it to the correct baud rate of 115200) to see the fetched weather data.
### Notes:
- You may need to adjust the latitude and longitude based on your location.
- Make sure that your Wi-Fi connection is stable and your Arduino board has permission to access the internet.
- You can use a JSON parser library like `ArduinoJson` to parse the weather data if you need to process it further.
