 Summary
Knowledge Bowl
 Is
a game between three four person
teams.
 A question is read and the first team to
“buzz” in gets to attempt an answer.

Administrator Controller: will be 5" by 3" by 1/4"
and will have only two buttons. One of which will
reset only the clock and the other will clear all teams

Defining interfaces
24-Oct-12 between components
Milestone description
Player controllers will have a potential voltage
difference of 5 volts between two contacts. A players
hand will connect between the two contacts and the
voltage that is not lost over the hand will got to a
comparator.

We need to
pick a resistor
value close to
R-bar so that
V+ will cross
the threshold
voltage set by
the
potentiometer.
Other Accomplishments needed
 Having
two metal contacts instead of
buttons on the player controller.
 Slow
down the clock speed for a counter (in
seconds).

Oscillator needs to be connected to a series
of counters to slow it down to seconds.

Minor/ Major Description
Minor
Make sure that the counter we implement is
working properly.
Major
Check whether or not the logic circuitry fits
properly onto a MOSIS chip
Minor
Decide how we want to construct the case that
will house the MOSIS chip.
Minor
Decide how we want to construct and power
the display.
Major
Make sure that all the parts needed to construct
this system are all on order.
Major
This is the primary plan on how to run the logic
needed for this system. We must have our
MOSIS design in by this time or we will have to
use our backup plan.
MOSIS Design
Issues & Concerns

Properly dividing the oscillator (clock) into
seconds using counters.
 Can
we get it to exact seconds?
 How many counters will it take?

Arduino microcontroller uno does not have
enough pins.
 We
will need to use an Arduino microcontroller
mega.
