You can use a MAC address generator, or one of the MAC addresses from the Arduino tutorials. Add Ethernet Shield: Next you need to specify the MAC address for the shield. Just snap it on top of the board as shown in the picture. Before you start, you will need to install Ethernet Shield on the Arduino. In this article you will learn how to setup Arduino to use Ethernet Shield, how to program it with Visuino, and how to connect to it from a Delphi application over the local network or Internet.
There are also cheap and simple ESP8266 WiFi modules that can be connected to the Arduino, so networking Arduinos is routinely done. In addition many of the more advanced Arduino boards and their clones come with WiFi or wired Ethernet built in. What if you want to collect data from many sensors spread over large area? Or what if you want to communicate with remote sensors over Internet? The basic Arduino UNO does not have built in network adapter, but there is Ethernet shield available for it. This opens a lot of interesting possibilities for collecting and processing live data, but the direct USB connection imposes some limitations. 1 ARDUINO: THE VISUINO PROJECT - PART 4 PAGE - 1/15 BY BOIAN MITOV In the previous articles, you learned how to program Arduino using Visuino, and how to communicate with it using USB simulated serial port from your Delphi code.
