Arduino Board Support
Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is
your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not
previously installed an Arduino library, please check out our installation guide.
Before programming the WiFi IR Blaster's ESP8266, you'll need to install the ESP8266 Arduino board
definitions. The board definitions can be found in the ESP8266 Arduino GitHub repository. For installation
instructions, check out this section of the README.
The WiFi Blaster board definition is not included with the Arduino ESP8266 board files, but it can be uploaded to
as a Generic ESP8266 Module. Verify your settings look like below:
