The topic of the Arduino came up around A&L's "virtual water cooler" last week. About a year and a half ago, I purchased a SparkFun Inventor's Kit for Arduino. The kit is a fun way for a hardware novice like me to get started and learn some basics. It comes with more than a dozen sample projects such as lighting LEDs, spinning a motor and generating audio.
Inspired by the discussion at A&L, I pulled my kit out this past weekend and put together the sample circuit that reads temperature. In addition to learning hardware, another ulterior motive in my Arduino purchase was to get my son interested in electronics. He's still a little young to really understand everything and instead likes to pretend the breadboard is a train. It makes it a little hard to put the circuit together as the "circuit train" travels around the tracks. But he does enjoy seeing the end result and playing with the circuits we make.
Integrating the Java code and writing a little thermometer widget. All of the resources needed for this project can be found here.
I finished everything up late last evening so my son has yet to see the end result. Something tells me he would be more impressed if I animated steam coming out of a train engine to represent the temperature.
There was a recent TED talk by one of the creators of Arduino. It's fascinating to see the types of projects people are completing with the Arduino. I think we're in for a fascinating future.
