Drip Trigger #3

I thought I should blip the electronic wizardry involved in my drip series.

Bottom left is the Arduino microprocessor with my circuitry on the board piggy-backed on top of it. The main function of this board is to completely isolate the various bits of equipment from each other so nothing gets damaged. The drip solenoid, flash and camera plug in on the right.

The board at the top left is a 16x2 character display which shows the settings being used. It also has buttons for modifying the settings and firing the trigger. This board sits on top of the other boards.

On the right you can see the drip solenoid which I got cheap off Ebay.
