Ok so here's my understanding so far of what I'll need.
I will need to get 2 of those valves4projects solenoids, since they are inline on/off valves I would have to design the device to close one valve then open the other valve. I will need to learn how to set up and use a Darlington Array to power the solenoids.
I recently picked up a basic electronic circuitry book and am burning through it like I should be my accounting book so I'm hoping this will give me a better understanding of basic electronics and I can start applying some crazy ideas to good use...i.e. arduino powered drink mixer?
