* This sketch demonstrates how to set up a simple HTTP-like server. | |
* The server will set a GPIO pin depending on the request | |
* http://server_ip/gpio/0 will set the GPIO2 low, | |
* http://server_ip/gpio/1 will set the GPIO2 high | |
* server_ip is the IP address of the ESP8266 module, will be | |
* printed to Serial when the module is connected. | |
