    Starting the enclosure for the knee lift electronics. I seem to like making it complicated!

    For the video above some people have shown an interest in the code so here it is in a zip file. This will open in most text readers if you only want to browse it, but to upload it to an Arduino microprocessor use the Arduino IDE software and paste the code in there. This is written in a version of C++.

    The code is flat, no library calls or function calls are made (except for the LCD library).
    There is some code duplication for similar functions, but I was OK with that.
    The pulse generation is coded directly, but libraries are available to do this for you.
    There are no interrupts, but it would be more elegant overall to use them.
    There are probably many other ways to do this and probably better ways!
    But it does work, and it runs fast enough for me.

    Use it, modify it, laugh at it, whatever works for you. If you do use it as it is right now then include the text at the beginning so people know the source.
