# BinBoo:  Building the front panel LEDs


[YouTube video 7KnUqjA6JTE](https://www.youtube.com/watch?v=7KnUqjA6JTE)


Short build-lapse video of building up the front panel "matrix" used in BinBoo.  This isn't a true LED matrix.  Instead it combining all of the LEDs into a common Anode, since the Cathodes are all controlled by individual outputs of the TLC5940.

I decided to wire up 16 LEDs, even though a binary clock only needs 11 or 12.  This gives some flexibility to other uses for the box, like a random sci-fi computer pattern.
