Motorized automatic blinds or automatic smart tint film.

Today, 1 year after buing these arduino uno and 16channel reley. I decided to set them them up with for new project. This is my first arduino and I dont have much knowledge with programing and electronics but Im super exited. So if I make this project work, I`ll continue with other ideas for home automatization with arduino.

My first projects is:
I would like to use motorized roller blinds or Smart tint film on 3 of my windows. Smart tint is instantly switching windows from opaque to clear in less than a second. What I would like is to have a privacy when it`s dark outside and light inside (when the lights are on) Smartfilm- the windows should be opaque.

And when is light outside and independent if its light or dark inside, the windows should be transparent or the rollerblinds up. I would like to over write that rule with my android not only from my Wifi connection but also outside of the house. To have a wired "on and of" switch would be also great. I live in a really sunny plase so it should be powered by solar panel.

I realize after some googling that 16ch reley and arduino is far from enough for this project. Would be reaaaly happy to know which components I need to buy and how to wire them. And of course the programing.
Thanks a lot for the arduino ! =)

Start easy and select the sensors and roller blinds, or whatever is required anyhow. Then find out how to control these items, relays may or may not be usable. Then write the code according to your requirements. Once this works, wifi or other components can be added.
