Teste do Shield Ethernet Seeeduino

details

Built a sketch that creates a web-server and set up a test environment with a LED and a temperature sensor.

I researched the options of the official shield and clones that used the chip W5100 of Wiznet. I chose to buy the clone manufactured by SeeedStudio. This board is a clone of the official ethernet shield Arduino but with some modifications, mainly to lower the cost:

  • Connector absence for SD memory
  • Absence of sockets and connectors for Arduino signs of replication. To access these signals is necessary to weld sockets and pins in the most convenient points.
  • The plate design was redone, putting all indicative leds activity, lined on one side of the plate

The board is well constructed and white finish. All examples present in 0018 Arduino environment for Ethernet shield, direct functioned smoothly. This shield for use Wiznet5100 chip and is connected to Arduino the same way as in the official shield uses examples Ethernet Shield without modification.

To test the shield, built a sketch that creates a web-server and set up a test environment with a LED and a temperature sensor.

The program running on the Arduino creates a web-server, provides the form below, and through a browser (firefox, internet explorer, etc.), enables on and off the LED and also display the temperature read from a sensor.

For this, I made an adaptation of the web-server sample program, the existing Arduino-0018 ide and used another example of the blog “http://www.scienceprog.com/” resulting in a short form. The program saves the LED status and keeps lit until clicked the option to turn it off.
