Good Morning,
is there someone that can help me with this ? I've the connection that stop to work after a fews times
/*
WiFi Web Server
A simple web server that shows the value of the analog input pins.
using a WiFi shield.
This example is written for a network using WPA encryption. For
WEP or WPA, change the WiFi.begin() call accordingly.
Circuit:
* WiFi shield attached
* Analog inputs attached to pins A0 through A5 (optional)
