CHALLENGES Domain

• Starting over all code/technology as of
  yesterday.
• Who wins if a button is pressed at the same time
  as a button on the touch panel?
• Large scale mobility. Can the next person who
  adds code easily add dimmers/non-dimmer outputs?
• Are we going to be blamed if the system is in the
  room next semester and the lights flicker?
• Do we need a lawyer?

13
CHALLENGES TechnicalHandyboard

• How to output to a particular location
• All I/O involves knowing a specific memory
  location
• Lack of memory
• TOO SLOW
• Timing, timing, timing.

14
CHALLENGES Technical New board

• Learning some new language?
• - another version of C?
• Starting over with a new board!
• - We dont know yet because we havent gotten it
  and we dont know exactly what were getting (out
  of stock issues)
