LED Strips[edit | edit source]
Network protocol[edit | edit source]
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.

LED segments[edit | edit source]
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.
