This is what I have for the code. Basically for my
sketch I have 3 motors running these pastels in a circular motion that create a
circular pattern of colors on a piece of paper. I would like 3 flex sensors to
control their own individual motor. Whenever a cake stamp is pressed with the
flex sensor attached underneath, a motor will spin. When the flex sensor is not
pressed the motor will not run.  I found
this test code that really was what I needed rather than the accelerating and
decelerating motor sketch so that depending on the pressure or the absence of
it the motor will spin. I need to incorporate the other 2 motors with 2 flex
sensors. I did layout the other 2 motors like the first motor sketch. I also
noticed when I did a test run, I could not get 2 motors to run. Is this because
the arduino cannot supply enough power to run two motors or even 3 motors?
