The buzzer.py script is pretty simple:
1) When buzzer.py first runs, it “announces itself” to any nodes that might be
looking for a buzzer they can use.
2) It blinks the yellow LED once a second (just to let you know the script is
running).
3) If you push the button on that node, a short beep will sound (just to let you know
the buzzer is working)
4) If any node broadcasts “who has a buzzer I can use?”, buzzer.py will answer
5) Other nodes can ask for a “beep” of a specified duration.
So, script buzzer.py basically provides a “buzzer service” that other nodes can take
advantage of.
Now look at the SN111 End Device node (Device Type = “Photo”), which should now be
running the DarkDetector.py script:
1) The yellow LED should be blinking once per second
2) Depending on the light levels and variance where the SN111 is sitting, it is either
showing a value of “00” on its display, or it might be displaying various values.
The displayed value represents a “percentage of darkness”, 00-99, with a value of
99 representing the maximum darkness level the node has ever seen.
The Dark Detector script is already monitoring for changes in light levels, but the script
also includes an “auto-calibration” capability. Since you have not “calibrated” the node
yet, no values will be acted upon.
Cover the photocell on the node with your finger. A value of “99” will be shown on the
display, and you should also hear a short beep from the other node (the SN171 Proto
Board, which is running the buzzer.py script we uploaded into it).
Now by “hovering” your finger at various heights above the photocell, you should be
able to vary the “darkness level” from 0 to 99%. Whenever you cross the 85% level, a
short beep should sound from the “buzzer.py” node.
In Portal, bring up the Node Info panel for the Dark Detector node, and expand the tree
of functions provided by the “DarkDetector” module.
