    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:

    Very useful if you wan't to build something with an Arduino. Simple to use and probably has button debounce.

    Cons:

    Except that the buttons aren't exactly aligned under the LED's there are none. But it's not a big deal.

    OtherThoughts:

    Very grateful for the library of rjbatista which makes it easy to use this module. http://code.google.com/p/tm1638-library/

    Bottomline:

    A really must have for Arduino beginners. In stead of all kind of PCB's with buttons or LED's which uses too many pins this one just uses 3 pins + 1 pin for each extra module.
