Arduino project 2

Finally, today I got almost all arduino parts to make the automated valve. I have found many useful blogs and forum from which I can get help but I still have some hard time to figure out what all small parts are intended for.
But for now, I would like to introduce the design I am thinking.

DIC analyzer and automated samples which I am going to make.

Ok, can I do this? Emm, it is going to be not easy but it worth to try.
