As a followup to our previous Ethernet web server example, I offer a enhanced version. Again, it displays what is coming in on the analog pins, but also allows you to control digital pins 0-7.
You’ll need:
Arduino UNO
Ethernet Shield
Plug shield into your home router with an ethernet cable. Change IP information to match your network, and MAC address to match your shield.
The html isn’t pretty, but it’s functional! I’m sure some of you can pretty it up, and even show the current status of the digital pins, like the status of the analog pins are displayed. Thanks to the What I did Was blog for inspiration!
