If you want to do animations that take into account the specific locations of the leds on the bookcase, 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.

Here's a sample sketch that makes use of these segments: [https://gist.github.com/scottyallen/ecaee28f537cf94e3aa30bb8347e0654 squares.ino]

The Bookshelves Flaschentaschen is an array of LEDs to light up the books in the Library.

  • STATUS: It may be out of commission after moving to 272 and in need of reconfiguration.

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.

Strip ESP8266 Pin Number of LEDs
Strip 1 1 277
Strip 2 2 277
Strip 3 3 24
Strip 4 4 39
Strip 5 5 14
Strip 6 6 9
Strip 7 7 105
Strip 8 8 65

The LEDs are WS2812B chips, with color order GRB.

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.
