Miniature theater - vieira_diniz - Mar-20-2020
Hello World!
Dear community;I'm creating a miniature theater to show a story in a cemetery. I intent to manipulate the puppet personages during a piece of music is playing and the lights illuminate the scenery.
Some images are down.
![[Image: 3f9uTXYTUe7ZaLtq8]](https://photos.app.goo.gl/3f9uTXYTUe7ZaLtq8)
I wrote the code, but I believe that it can be more simple and with less redundancy to work well. I don't know why, but some lights start "on" when I'd like to start all "off".
Can someone help me to improve my code? Any help is welcome!

I would use a parser and a specific format that describes the entire action.
The following is a sketch, but is almost completed, and probably will be helpful for you.

# ... define the same way all 12 items/switches?!
'int_caveira': 11
'geral': 12
}
takt_executors = {

'mstop': '_mstop_exec',
'o': '_o_exec',
's': '_s_exec'

self.iface = GPIO

for actor, num in Theater.actors.items():
self.iface.setup(num)
def output(self):
""" Docstring needs be here.

"""
# is this allowed, or you need to split
# it into 2 separated for-loops?

self.iface.output(num, False)
self.iface.PWM(num, Theater.freq).start(0)

if self.episode is None:
# I don't know, where it will be printed in case of GPIO?!
print("No episode was loaded. Load an episode first")

if mode == 'always':

self._play()

# mstop, mplay -- stop and play music respectively
theater = Theater()
theater.load_episode(episode)
theater.play(mode='always')I am sorry about too few comments ( I am tired), but I hope the code is self-explanatoryand almost working...

UPD: I updated the code. It is not tested, however. The main idea is to use human understandable commands
that describe the theatrical performance. If you look at
episode variable, it is just a string. Each new line is a new command. Awesome invention, I think. Hope that helps.
