A lot of people have used ESP8266 to add inexpensive WiFi connectivity to their projects, but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266.

One place thing that more people need to know about is how to program directly for this chip. Too many times projects use it ... the ESP8266 is a lot like programming an Arduino.

For many people who like to build things that use Arduino to operate one of the most difficult parts is making an app or software to control ... for Spark Core and ESP8266 is also planned.
