Before  You  Start,  First  Learn…  •  Addi5ve  color  (light)  model  

•  Trichroma5c  color  percep5on  

•  Red/Green/Blue  (RGB)  colorspace  

•  Non-­‐linear  brightness  percep5on  •  Raw  Spectra  vs.  “Rainbows”  

•  Inherent  brightness  (re:  yellow)  

•  24-­‐bit  RGB  color  representa5on  

•  Refresh  rate,  persistence  of  vision  

•  LED  opera5onal  basics  •  Pulse-­‐width  modula5on  

•  Basic  computer  anima5on  

•  Double  buffering  

•  Electrical  and  breadboarding  basics  

•  Digital  logic  basics  •  Clocked  serial  communica5on  (SPI)  

•  Microcontroller  basics  (e.g.,  no  OS,  etc.)  

•  Arduino  basics  (setup/loop,  preprocessor)  

•  gcc  4.3.x  toolchain  

•  C++  classes  &  methods  •  C++  memory,  pointers,  structs  &  arrays  

•  C++  operator  overloading  (e.g.  %=)  

•  Inline  assembly  language  

•  Harvard  vs.  von  Neumann  architectures  

•  AVR/ATmega  MCU  architecture  •  8-­‐bit  MCU  issues  (e.g.  int  =  16  bits)  

•  Satura5ng  arithme5c  &  ISO/IEC  N1169  

•  ATmega  328  port-­‐to-­‐pin  mappings  

•  Disassembly  of  compiler  output  

•  Cycle  coun5ng  for  required  5mings  •  “prine  debugging”  

On  Second  Thought,  Let’s  Just  Play:  

1.  Connect  Arduino,  run  test  code  (“cookbook”)  -­‐  USB  connec5on,  Arduino  IDE,  basic  “Blink”  sketch  

2.  Hook  up  LED  strip,  sample  code  (“cookbook”)  -­‐  Run  code,  see  LEDs  on  strip  light  up.  Woo!  

3.  Receive  your  mission  instruc5ons  

-­‐  Play  with  der  Blinkenlights.
