A simple TCP Server & Arduino Sketch. Connects a wifi-enabled (ESP8266) Arduino-nano-like board to a TCP server via a socket connection.

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.

My problem is that I can't use this code to an Arduino Mega with LAN shield, only on a NODE MCU ESP8266. I need more IO ports than NODEMCU has, and LAN connection also.
