aka - an elaborate blinky sketch with a start/stop push button and a relay

This sketch closes a relay or other device/component that controls the remote shutter on a digital camera.

Consult camera manual on how to connect relay to remote shutter for your specific camera.

Most cameras have a short to ground remote shutter control, but check your camera's specifics so you don't damage your camera.

Two modes of operation:

1. Serial port control through the USB port connected to a PC

   Current commands:

    ~NUM - Sets the number of exposures to take (-1 infinite)
    ~INT - Sets the length of the shutter open in milli seconds
    ~SPC - Sets the delay between sequences (shutter closed)
    ~MIR - Sets the mirror lift delay (must match camera setting)
    ~RUN - Starts the exposure sequence using the prescribed values
    ~STP - Stops the exposure sequence
    ~RST - Stops the exposure sequence and resets the variables to default
   

2. Push button starts and stops exposure sequence, check code for pin number.
