ESP8266 Wi-Fi Control Relay Using NodeJS & JohnnyFive

For this project we are going to flash a custom version of Firmata… first, we will create it with Firmata Builder, set some Wi-Fi and debug variables to our ESP8266, and connect up a Relay. Then we will Install Node.js, Johnny Five js and some other libraries on Windows 10, write a controlling script and run it from the Windows command line to turn the Relay On or Off.
