Description
-----------
An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's [Grove 4 digit display](http://www.seeedstudio.com/depot/grove-4digit-display-p-1198.html). The TM1637 chip also has keyboard input capability, but it's not implemented in this library.
