Configuration
Each Arduino sketch for this guide uses a single config.h file that stores your WiFi and Adafruit IO credentials. There are placeholders in that file that need to be replaced with values specific to your WiFi network and Adafruit IO account. Make changes and use that file with each of the sketches on subsequent pages in this guide: copy it into the directory for each sketch. The ESP/Adafruit IO guide walks you through making those changes.

Libraries
To build the code in this guide you will need to use the Arduino Library Manager to install the latest versions of the Adafruit_Seesaw, Adafruit_IO_Arduino, and ArduinoHTTPClient libraries. If you haven't installed Adafruit libraries into your Arduino environment before, see this guide.
