ESP32 tutorial: Retrieving Thingspeak data with a mobile app

📱 In this tutorial, we learn how to get data from Thingspeak using an application created with MIT App Inventor.

⏰ The ESP32 periodically sends data to Thingspeak, and the app sends a request to the platform to retrieve the last value of a specific field.

🔍 The app sends an HTTP request to Thingspeak and receives the requested data as the response.

💻 The speaker modifies the result list to start counting from one instead of zero, making the process less confusing.

🔢 The last value shown on the speaker's phone is 10, and they mention that the full code and app can be found in the video description.
