+ WiFiEsp example: WebServer
+
+ A simple web server that shows the value of the analog input 
+ pins via a web page using an ESP8266 module.
+ This sketch will print the IP address of your ESP8266 module (once connected)
+ to the Serial monitor. From there, you can open that address in a web browser
+ to display the web page.
+ The web page will be automatically refreshed each 20 seconds.
+
+ For more details see: http://yaab-arduino.blogspot.com/p/wifiesp.html
