ARDUINO ETHERNET SHIELD W5100 – TUTORIAL(português)
This project is tutorial of Ethernet shield. You can monitor your sensors, keys, and LED through the browser using your computer.
Parts
- Arduino Uno
- Arduino Ethernet shield
- LED 2 and registor 2
Wiring
Go to the START menu, and then type the command CMD in the dialog box and press ENTER.
You’ll need them to configure the Arduino Ethernet Shield W5100.

To test the operation of the system, just open your favorite web browser on your computer and type in the IP address bar followed by the access door that you configured earlier in the program. For the test made by author the IP was 192.168.1.177:8080. The access door is defined by the “EthernetServer server (8080)”
