python-clewareampel
Control the Cleware USB Ampel (traffic lights) with Python.
In this version only one Ampel can be controlled. It was not tested what will happen when you have two Ampels plugged.
In code
from clewareampel import ClewareAmpel
with ClewareAmpel as ampel:
ampel.green_only()
Have a look into example.py or just run it to see if your Ampel is working.
On the command line
usage: clewareampel.py [-h] [--all-on] [--off] [--red] [--red-on] [--red-off]
[--yellow] [--yellow-on] [--yellow-off] [--green]
[--green-on] [--green-off]

--red-on Switch red light on
