Hi Lefty.
This is how I have modified the sketch. The system is fot actuating valves for drip photography. I have got the sensors, and delay system to trigger the shutter and the flash so everthing now works. I will now have to start studying the software, because I would like an lcd to display my settings.
Thanks for your help.
