To run hauntedpi

$ python main.py

Update the constants.py file with the details of your inputs and outputs

For each scene you wish to configure create a file in the scenes dir. See the files in that directory for examples but you should just make calls to the director methods to play sound and switch you outputs.

Configure a GPIO for input. This function returns the channel so can also be used to define constants for each channel

e.g to define a constant for a push button on GPIO 5 BUTTON_5 = director.add_input(5)

Configure a GPIO for output. This function returns the channel so can also be used to define constants for each channel

e.g to define a constant for a relay switch on GPIO 5 RELAY_5 = director.add_output(5)

You can also optionally pass the inital value so the same call with default output HIGH would be RELAY_5 = director.add_output(5, True)

Call a function when an input GPIO is triggered

e.g to call the function play when GPIO 5 is triggered director.add_trigger(5, play, ()))

Schedules a function to be called after the defined delay in seconds

e.g to call the play function after 10 seconds director.schedule(play, (), 10)

Sets an output HIGH. Takes optional delay and duration. Passing a duration will turn the output LOW after duration seconds

e.g to set GPIO 23 HIGH for 10 seconds in 20 seconds time director.set_on(23, 20, 10)

Sets an output LOW. Takes optional delay and duration. Passing a duration will turn the output HIGH after duration seconds

e.g to set GPIO 23 LOW for 10 seconds in 20 seconds time director.set_off(23, 20, 10)

Play the sound at the given file location.

$ sudo apt-get update $ sudo apt-get upgrade

$ sudo apt-get install python-pygame

If there is no sound from your pi when playing a sound file. You can run the following command to set the audio output Last number can also be 1 to force headphones.

$ sudo amixer cset numid=3 0
