First of all, the Project Sun SPOT official URL is http://www.sunspotworld.com/. You can download SDK, tutorials and manuals here. You can also ask your questions at the forum in this site as well as purchase Sun SPOT Java Development Kit. So this is the start point for your Sun SPOT life.
Before installing Sun SPOT SDK on your computer, you need
- Java Development Kit (JDK) from Sun (Sun Java SE 1.5 or later)
- Apache Ant
- NetBeans (optional, but I assume you have one for this Servo Car blog entry)
Now, we've had all stuff, hardware & software, to write a code for the Sun SPOT Servo Car. Next time, I'm planning to begin with a very simple code other than this, but if you'd like to try it in advance, you can freely check out it from https://servocar-spots.dev.java.net/.
