Hi.

This is an intervalometer sketch for an Arduino board (removed the stepper code) based on the former project with the dithering mechanism.

The program is controlled by a 3 position switch - light frames - pause - calibration frames with an auto-off function, reset by the board reset button or by switching the power off/on.

It will wake up as required, take a defined number of light frames (as many as you want) and terminate - or just keep going until paused.

It will take flats, bias and dark frames, switching an EL panel for flats - under development. For now, it's necessary to fit and remove the light box. It would be good to fit the light box and leave it there. So it needs to become a dark box!!! some of the time. Have some ideas on how to do this with a minimum of fuss, moving parts etc etc.

Delay functions can be set to user preference - e.g, cool down time between dark frames, settle time for mirror lock up, interval between light frames and so on.
