hi Liam
Thanks for your reply.
The file name for the very first script in this discussion I entitled rotary menu from A I internet.py .
The second script that I uploaded (twice) is titled ‘rotary menu modified A I.py’
Here is the code for “script 1.py”
#works with the off time different to on time

# Define colors

GREEN = (0, 255, 0)
ORANGE = (200, 30, 0)

OFF_DELAY = 0.2 # Time in seconds for the pixels to be off (different from ON_DELAY)
def set_all_pixels(color):
"""Sets all pixels on the strip to a given color."""
for i in range(NUM_PIXELS):
np[i] = color
np.write()
while True:

These scripts 1,2,3….py do not have “machine reset at the end but I will try that now.
Thank you again.
