Python all_leds_off Examples

Example #1

import tree

L0 = 1
L1 = 2
L2 = 4
L3 = 8
L4 = 16
L5 = 32
L6 = 64
ALL = 1 + 2 + 4 + 8 + 16 + 32 + 64
NO_LEDS = 0

tree.setup()  # you must always call setup() first!

# Pattern: two or three LEDs are on at the same time.
# Note that each pair is on for 0.4 seconds

for i in range(7):  # repeat the pattern 7 times
    tree.leds_on_and_wait(L1 + L4, 0.4)  # LED 1 and LED 4
    tree.leds_on_and_wait(L5 + L3 + L0, 0.4)  # LEDs 5, 3 and 0
    tree.leds_on_and_wait(L2 + L6, 0.4)  # LEDs 2 and 6
    tree.leds_on_and_wait(L5 + L3 + L0, 0.4)  # LEDs 5, 3 and 0

tree.all_leds_off()  # extinguish all LEDs

# All done!
tree.cleanup()  # call cleanup() at the end
