1  Using Arduino / Project Guidance / Re: Multiple Arduinos on same network on: August 03, 2011, 12:28:54 am
I had to dig deep to find it in the .cpp files for Ethernet, DHCP and CIAO.  If anyone wants to use multiple Arduinos on a broadcast domain, they WILL need to change the default names.

Thanks for using Ciao. I updated the Ciao documentation to explicitly state how to set the Arduino's hostname. In short, you use the three-argument variant of Ciao.begin(). Instead of a call like this:

Ciao.begin("TARGET 01", 5281);

make a call like this:

Ciao.begin("arduino1", "TARGET 01", 5281);

and the Arduino will show up on the network as arduino1. As you can see from the Ciao code, the library passes the hostname directly to EthernetBonjour, which is an amazing, magical library that announces the Arduino over Bonjour. EthernetBonjour helps make Ciao possible, so I made a conscious decision to generally get out if its way. I did that by exposing all of the power and functionality that Ciao uses from EthernetBonjour, including the setting the hostname.
2  Development / Other Software Development / Avviso: Push notifications via Prowl on: May 14, 2011, 04:16:19 am
I posted the source to Avviso, my Arduino and Processing libraries and examples for sending push notifications to your iOS device via Prowl. Avviso works best with an Arduino and Ethernet shield, but it can also work with a USB Arduino and the included Processing library. Apple's push notification service is fast, direct, and free. Consider using it in your Arduino project along with the traditional alternatives of email, Twitter, or SMS.

Thanks to Prowl for dropping the SSL requirement from its API in January 2011, which made it possible for the Arduino to communicate with the service directly. (Avviso with Processing on the PC still uses SSL, of course.)
3  Community / Products and Services / Ciao: Say hello to your Arduino over Bonjour on: April 27, 2011, 05:32:47 pm
Ciao is an iOS app to talk to your Arduino. It finds your Arduino on your local network automatically using Bonjour, and it works with Arduinos with Ethernet shields or over USB (using a Processing sketch on your computer). Find out more on the Ciao homepage. It's $5 on the App Store, but I'll give away 5 free promo codes to the first 5 forum users who send me a personal message via the forum.
