Share My Creation THime - LED Display Time, Temperature, Humidity

The goal of this Make Project THime is a LEGO ® module to display in a 4-Bit LED display, the time or temperature & humidity. Control of the display via Infrared. Powered by an Arduino UNO.

See here for details. Download B4R source.
Additional libraries used: rLEDControl v1.0, rTM1637 v1.2 - included in the source.

... How fun it is to make simple modules coded with B4R ...

Hi rwblinn,
Nice project, I think I will do the same.
With a bit of Lego it's a good idea, I'm sure our little kids will love it :)
