Adafruit IO Arduino Library
Adafruit IO Arduino Client Library


This is the documentation for the Adafruit IO Arduino library. This library provides a simple device independent interface for interacting with Adafruit IO using Arduino. It allows you to switch between WiFi (ESP8266, ESP32, AirLift, WINC1500, & WICED), Cellular (32u4 FONA), and Ethernet (Ethernet FeatherWing)

Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!


This library depends on ArduinoHTTPClient and Adafruit MQTT Library being present on your system. Please make sure you have installed the latest version before using this library.
