Connect Arduino to internet over USB (with Processing) - Simple Space Weather meter example (Part 2)

The video tutorial guides viewers through accessing space weather data using an API, parsing JSON data, and using HTTP requests in Processing. It then demonstrates how to send this data to an Arduino to control LEDs, providing a practical example of integrating software and hardware. The tutorial covers key concepts such as JSON parsing, HTTP requests, and serial communication with Arduino.

Discuss the role of the HTTP requests library in the processing sketch.
