Bookshelves

LED Strips

Network protocol

The LEDs are controlled by an esp8266 that's on the network. The network address is bookcase.noise. It uses the flaschen taschen UDP protocol on port 1337. The bookcase is addressed as a 810x1 pixel grid. More info and libraries can be found on Github. Check out client/rainbowbookcase.py or client/squares.py for simple examples of how to write code to control the bookcase.

The LEDs are WS2812B chips, with color order GRB.

LED segments

Here's a complete mapping of each led segment, where a segment is defined as the strip of led between any intersection with another led strip. This is handled for you if you use the Bookcase class in bookcase.py.
