literbox Fenix

Hey, I have an idea, if you like to "bug" with, well, go head.
I'm totally new to programming/electrical/ect, I'm no one.
I will need a lot of help if you are interested in helping me?
you are welcome to help.
I have no idea what I'm doing here or what is what but I have an idea that I really like to do.

It is a self-cleaning litter box for cats, Literbox-of-Fenix.

It should be fun to do something I'm not good at :)
About me: I'm not an electrician/programmer/etc. Sometimes it's hard to understand.
