This Meetup is past

2 people went


Come join us at Education Center in Plano TX to learn how to use an ethernet shield with the Arduino. In this class we will be covering the following:

The Ethernet shield, Part 1 ( (23:55) In this 2-part presentation you will learn how to get your Arduino gadget to speak to the Internet! In part 1, you will learn how to connect your Ethernet shield, and how to make your Arduino part of your local network. Specifically, you will be shown how to connect to the network by automatically acquiring an IP address via DHCP, or how to acquire an IP address manually. In this presentation, I use the original Arduino Ethernet shield that is based on the w5100 chip.

Ethernet shields with the w5200 chip are more common these days. To use a w5200-based shield, you will need to download the Ethernet_V2 library and use it instead of the one I use in the presentation. I link to Seedstudio which contains this library is available in the external resources.

The Ethernet shield, Part 2 ( (14:15) In this 2nd part, you will learn how to turn on and off an LED, and to read light intensity through a Telnet connection to your Arduino from your computer. Parts Needed:

Arduino UNO ( An LED ( A 1KΩ Resistor (
