Code for the Raspberry Pi 4 - 2022 Dexter Co-op Pre-school Christmas Light Show
This 2022 lightshow was architected for a float with six poles: three poles on the left and right side.
I named each zone from zero to five. From there, I grouped the channels, representing each side of the float: 0-2 (Group One), 3-5 (Group Two).
To find all the combinations with repetition, you can use itertools' great product method:
for i in itertools.product([0, 1, 2], [3, 4, 5]):
print(i)
This provides a reasonable starting place for all cross-channel (Group One <-> Group Two) mappings. Next, create some all-channel mappings for variety and "whole-float" effects. Each of these patterns can be used in the .seq file in the sequences folder. The lightshow.py driver application calls an if/then loop, that catches the pattern and triggeres the appropriate GPIOs HIGH or LOW on the Raspberry Pi.
Channel and group mappings used:
0 - ZERO
1 - ONE
2 - TWO
3 - THREE
4 - FOUR
5 - FIVE
0,3 - PAIR_ONE
1,4 - PAIR_TWO
2,5 - PAIR_THREE
0,5 - DIAGONAL_ONE
2,3 - DIAGONAL_TWO
0,4 - DOWN_RIGHT_ONE
1,5 - DOWN_RIGHT_TWO
1,3 - DOWN_LEFT_ONE
2,4 - DOWN_LEFT_TWO
0,1,2,3,4,5 - ALL_ON
0,1,2,3,4,5 - ALL_OFF
0,1,2,3,4,5 - FORWARD
0,1,2,3,4,5 - REVERSE
0,1,2,3,4,5 - OUTSIDE_IN
0,1,2,3,4,5 - INSIDE_OUT
0,1,2,3,4,5 - SPLIT_CHANNELS_ONE
0,1,2,3,4,5 - SPLIT_CHANNELS_TWO
0,1,2,3,4,5 - CIRCLE
0,1,2,3,4,5 - RANDOM
0,1,2,3,4,5 - END
The first number in the sequence file is the timing. Timing is when the effect should take place. The duration is the second number. This informs lightshow how long the action should take to complete. If the duration is left blank, the default duration of
For a demonstration of the sequence timings and durations, try demo.seq in the sequences folder.
