Connecting to the Cloud

This clock doesn't just tick; it thinks! By connecting to the internet, it can fetch data that it can't measure itself, like the weather forecast for tomorrow.

APIs (Application Programming Interfaces)

An API is like a menu for a restaurant. We send a request ("Give me the weather for London"), and the server sends back the "food" (data).

We will use the OpenWeatherMap API. The data usually comes back in JSON format:

{
  "weather": [
    {
      "main": "Rain",
      "description": "light rain"
    }
  ],
  "main": {
    "temp": 285.32
  }
}
