I'm in high school taking a capstone course where I have to create/invent something for a grade. I was wondering what kind of PLC I should use. I need to display three numbers and have a three input switch for off/on1/on2 and it needs to be at wrist watch size. Any recommendations on what kind of chip/parts I'm looking for would be awesome.

Here is a reference for you so you can do some research. This is an excellent company.
