Here’s the nitty-gritty.
Parsing HTML on Arduino usually demands minimal footprint libraries due to limited device resources.
Working with the Arduino requires the WiFiNINA library for network features.

To make this happen on an Arduino, you first need to include the necessary libraries – typically <ESP8266WiFi.h> for ESP8266 or <WiFi.h> for ESP32, and <Base64.h> for encoding authentication details.
