SPOT Library

For this task, I mainly read some documents such as tutorials , guides and javadocs, and also studied some source code of demos.

The following two SPOT libraries are important for implementing Task 2:

com.sun.spot.peripheral : "Interfaces and classes dealing with the hardware on the SPOT processor board."[1]

com.sun.spot.sensorboard : "Contains highest level interfaces and concrete classes that make up the SunSPOT sensorboard libraries."[1]

Demos:

BounceDemo-OnSPOT
"In this demo, the row of LEDs on the top board of each Sun SPOT
represents a tube. Note the red LEDs at either end of the LED row.
Each represents a cork that keeps the ball in the tube. At first, the
ball on any Sun SPOT will be blue. However, if the Sun SPOTs are
able to communicate with each other, they will allocate different
colors for the ectoplasmic balls to avoid, as much as possible, duplication."[2]

AirText
"This application uses the linear array of tricolor LEDs on the eDemoboard
and "persistence of vision" to display text in thin air when the SPOT is
moved back and forth."[3]

BroadcastSample
"This simple demo shows you how to use the radio to broadcast some
data to any listening SPOT(s)."[4]

RadioStrength
"A simple application for 2 SPOTs. Each SPOT broadcasts 5 packets per
second and listens for radio broadcasts from the other SPOT. The radio
signal strength of the packets received is displayed in the SPOT's LEDs."[5]
