Project 1 - Getting Started with the SPOTs
Due - Wednesday, September 10, 2008
The goal of this assignment is to familiarize you with the SunSPOTs and
get you started on your semester-long project. Begin by reading the SPOT
Part 1 - Demos
0. Run the following demos:
1. (10 points) Implement a program that displays the current temperature
using "persistence of vision" as the AirText demo does.
2. (15 points) Implement a program that displays the current temperature in
binary using the LEDs. A 1 is represented by an on LED and a 0 is
represented by an off LED. A temperature of 70 degrees would be represented
as follows: LED: off - LED: on - LED: off - LED: off - LED:
off - LED: on - LED: on - LED: off
Part 2 - Movement Detection
1. (75 points) Implement a program that senses movement of a SPOT and
notifies the entire network if movement occurs. For this assignment,
you can assume that the network diameter is at most 7. If a SPOT receives
notification of movement anywhere in the network, it will change its LED
color to red and turn on its LEDs. Additional requirements and details are
- Use the IAccelerometer3DThresholdListener to
determine whether movement has occurred.
- Use the RadiogramConnection
class to broadcast messages on port 42. All SPOTs will also listen on
port 42 for message from the rest of the network.
- All messages contain an integer to represent the message type followed
by an optional payload. Use 51 to represent a movement detected message. The payload
of the movement detected message is a string representing the time at
which the movement was detected. See java.util.Date for the
appropriate format of the Date string. Make sure to verify that a message
is of the appropriate type before processing it.
- You may need to use the ISleepManager class to disable deep
sleeping such that a SPOT can always receive and forward messages.
