The ESP8266 based Feather HUZZAH & the HUZZAH ESP8266 breakout are both very popular options for connecting projects to Adafruit IO. In this guide we are going to walk through the setup needed to get your ESP8266 up and running with the Arduino IDE & Adafruit IO. This same basic setup can be used as you progress through our Adafruit IO Basics series of guides.
Inventables' web based digital CNC software, Easel, currently requires a constant connection from a Mac or Windows based machine in order to send commands to the X-Carve over a serial port. This tutorial will show you how you can free up your main computer while the X-Carve is running by using a Raspberry Pi as a bridge to wirelessly send commands to the X-Carve's Arduino Uno. We will also use a Powerswitch Tail to automatically control the main power to the X-Carve when Easel launches in your web browser.
