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


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


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


    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.
