The nonsense starts here:
===================
root.mainloop()
while colour == None:
led.pulse(red=0, green=255, blue=0, repeats=1, duration=5000,
steps=50)
while colour == 1:
led.pulse(red=255, green=0, blue=0, repeats=1, duration=3000,
steps=50)
timered += 1
while colour == 2:
led.pulse(red=255, green=255, blue=0, repeats=1, duration=3000,
steps=50)
timeyellow += 1
while colour == 3:
led.pulse(red=0, green=0, blue=255, repeats=1, duration=2000,
steps=50)
timeblue += 1
====================
it seems you don't understand event based programming. root.mainloop()
never exits. It waits for the user input and does the dispatching, i.e.
when a key is pressed, then according to your bindings, the functions
red1, yellow1, blue1 are called, which set a variable but do not do
nything else. To see that, just insert a print statement into these
functions:
def red1(event):
colour = 1
print("Red ws called")
Now your job is to also do the functionality there, i.e. you have to
reformulate your task (waiting for red, then blue...) as a state
machine. Alternatively you can circumvent to redo the logic in a state
machine by using a coroutine.
You should read a text about GUI programming, or more specifically event
based programming, to understand your mistake.
