Enthusiast Dave McGuire has just released details of his GENT ("Good Enough Network Tool") which can perform a variety of functions once connected to a network, including getting an IP address; allowing you to assign an IP address, subnet mask, gateway, and DNS; ping any IP address; "Discover" via ping a range of IP addresses and display them; do a basic port scan on a specific IP address and more as he works on the sketch. The hardware is based on an Arduino Mega with an Ethernet shield, a typical numeric keypad and LCD display. In the following video Dave runs through the operation:
That's a pretty cool project, and an excellent example of what can be done with an Ethernet-enabled Arduino system. For more information, discussion and sketch details login to the Arduino forum. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
Quite simple the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
