A lab report by Michael Chan
Link to a video of your virbation motor
a. Which color wires correspond to power, ground and signal?
Red is the power, brown is the ground and ornage is the signal.
a. Which Arduino pin should the signal line of the servo be attached to?
It should be on pin 9 per the myservo.attach line of code.
b. What aspects of the Servo code control angle or speed?
The angle is controlled by the intialization of the for loops. The 180 to 0 tells the servo to rotate from 0 to 180 degrees. The steps in the for loop indicate how fast it should change angle, in this case it is set at 1 degree.
Include a photo/movie of your raw circuit in action.
a. Make a video of your proto puppet.
a. Make a video of your final design.
I attempted to assemble the countdown paper puppet, however i was unable to get good enough contact with the screw and paper to make the paper actually rotate around and coutndown.
