The most easy and "barbaric" way to get a strip light is more than cheap. All you need is a long (tall) and slim box, some aluminium foil (food aluminium foil), some liquid glue (not super glue), some sort of tape, a knife, a beer to keep company and 30-40 minutes.
After I finished the first test with the Ethernet shield and serving your own page from Arduino (see post here Arduino - Talking plant, with HTTP server (or how to see sensor data via internet)) I said, ok, but if I don't have my own static IP address!?!? Most of us don't have a static IP address at home. Yeah it was fun with the other one to play in a LAN or use the university network to get an own IP, but at home this device renders useless. I tried with other social networks or email providers but it looks like Facebook, Yahoo mail and Gmail have quite some problems talking with Arduino and Arduino has some problems talking with them, the only one available remained Twitter.
One of the small assignments used for learning Arduino was the classical "talking plant". Actually was more of a build own humidity sensor, sensor reading and sending the data to the Ethernet shield and also use LED lights to display the status of the soil moisture.
To continue my first post on speed measurement I will show how I made the arduino part more "interesting" and connected it to flash and as3.
For connecting arduino with flash I used TinkerProxy, it has instructions on how to use it so I will not get into details.
The flash file will receive the speed value and will capture a picture from the webcam. (Note, for my project I used a webcam to take pictures of the objects that passing). Also it adds to the picture the time stamp and the speed. (processing the image at the runtime). The picture is then saved to the server with a php script.
