Sequentialy Controling Piface Outputs

hiteccol80

Help!

 

I'm a complete noob at Python, although do have a background in computer hardware and electronics.

 

I have a Pi B+ and a PiFaceDigital 2 - all working fine and I can control each of the outputs from the emulator and the command line in code using one of the examples provided etc.

 

I want to create a programe that does the following:

 

1)     Wait for an input on one of the inputs (a push switch or similar - there will be four connected)

2)     When a push switch is activiated, commence a sequence of turning each output on for 3 seconds then off before moving on to the next output for three seconds untill each output has been sequentually activated for three seconds then stop.

 

I can control the outputs from the emulator and in code from the command line, but am struggling with the above sequence.

 

As I'm a programming noob, I could do with seeing some examples of code - I'm quick to learn, and can adapt stuff, but I'm really struggling with putting this sequence together for the PiFaceDigital board.

 

Any ideas? Help very much appreciated.

 

Thanks!

  • Let me state up front I am not a formally trained programmer. I refer to my skills as Resurrectionist or Frankenstein programming.

     

    Resurrectionists were paid  body snatchers. They exhumed the bodies of the recently dead for anatomists in the United Kingdom during the 18th and 19th centuries.  In Mary Shelley’s  classic horror novel Frankenstein, Dr. Frankenstein stitches together an assortment of stolen body parts and attempts to imbue life into his creation.

     

    I cull Internet search returns looking for code parts I can reuse. Before starting a project I usually have to read some basic documentation (i.e. manual) to get an idea of what I am looking for. I suggest grabbing the documentation for gpiozero, I think 1.5 is the latest version. Take a look at the examples of a using a button and timing.

     

    I have a button activated routine that is body snatched and a timing routine that is also body snatched. They are in two different scripts that I rolled up into the attached zip file. It would require you to take the switch routine from one script and the timing routine from the other script an make your own Frankenstein from the parts.

    Many thanks for your helpful and prompt reply.  I am sure I can use some of these body parts in my own grotesque Frankenstein creation.

    Best wishes
