All in tree steps for beginners
Download and unzip in your Arduino libraries folder "ENC28J60 EtherShield Library"s
www.kmtronic.com/software/DINo/EtherShield_Arduino_v2.zip
Connect board to USB, open "EtherShield_webserver" example,
modify if necessary MAC and IP address
and upload to board
Connect to your Router or PC Network Card and check for PING
Now time to fun and guaranty some sleepless nights!
No PING received?
Don't worry, we spend a lot of time and test many examples, so will help you.
What projects you can realize using this board?
Some ideas ...
--- Build a garage door opener with Internet or IPhone ---
--- Control using WEB any high or low voltage equipment ---
--- Build simple home automation and control lamps or other home equipment ---
--- Longing processes and save to WEB server SQL base ---
--- Build long distance 4 lines extender using two board connected directly or using Enthernet ---
and many more ...
When you sure that hardware works is time you to
build your "Hello Word" project
and learn step by step.
