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)
