Final Project: Prior Iterations of the Code

Rev 3: This code attempts to separate the force of shaking into a soft, medium, and hard range.

Revision 1:

/* read the amount of shaking

determine the force exherted, F=ma

count the time of shaking

when the force * time hits a certain threshold, turn on the led

count the number of button pushes

print the number of uses left

when the number of uses equals zero, print "refill needed"

--to be sufficiently mixed, F*time = x, use x as threshold

--also must use x,y,z direction, so take the vector sum to get the overall force

--time should start counting when above another total acceleration threshold
