Now that the protocol for basic communication with the TI chronos ez430 has been worked out (see previous posts) I needed to work on something useful. So I set out to try and control my wireless light switch with the watch. Sadly the RF receiver supplied with the chronos does not use a protocol which is likely to ever be compatible with the arduino so this example requires a computer.

IDEO labs shows you how to connect the Arduino to the Nokia 770-
In the vein of Arduino-controlled espresso machines and Lego bots, we’ve been playing around with Flash and the Nokia 770 Internet Tablet. With its flexible Linux-based OS, the Nokia 770 is great for rapid prototyping. Plus, you can snag one on the cheap ($65-170 on eBay).
Hardware aside, Flash is a great language for quick prototyping. It’s an environment that many designers are already familiar with, and it enables the user to create a graphic interface in minutes. For prototyping on small screens, Flash Lite can be used, but Flash Lite cannot communicate to other devices outside of the device it’s running on (aside from calling other phones). The Nokia Internet tablets are interesting because they are essentially tiny Linux computers and run full-fledged Flash. We got one of these tablets to run Flash and talk to an Arduino board. This enables any kind of sensor to communicate with the Flash application and allows the app to control things like lights and motors.
Detailed instructions for setting this up can be found in our Google Code wiki (here and here)…

ZigBee is a low-power communication system using digital radios. It’s intended to be easier to work with than Bluetooth. Adafruit recently added an adapter board for Digi’s XBee product line and has put together a great how-to to show the devices potential. Using two XBee radios and adapters you can wirelessly program an Arduino board. This would be great if your Arduino was installed in an inaccessible area or maybe it’s over 100feet away from where you’re working. The radios do serial communication just fine. What the how-to covers is getting the reset line working so the Arduino can restart automatically after you program it. Once the radio pair is configured properly, it will pass the RTS line state directly from one device to the other.
