This library provides a simple device independent interface for interacting with [Adafruit IO](https://io.adafruit.com) using Arduino. It allows you to switch between WiFi (ESP8266, ESP32, ESP32-S2, ESP32-S3, ESP32-C3, Airlift, WINC1500, & WICED), Cellular (32u4 FONA), and Ethernet (Ethernet FeatherWing).
