WHAT ARE WE BUILDING?
In project 2, we’re going to take what we learned about the steps needed to
make our servo mode and add a crucial feature: two push-buttons that will
allow us to actively control the angle of our motor. In project 1, if we wanted
to change the angle of our motor, we needed to change the desired angle
in our code, then reupload our sketch. By adding two push-buttons, we can
use one to increase the angle of our motor and another to decrease it.
Now that our motor is moving, we need to add a method of controlling its
position. It’s pretty rare that a robotic arm moves to a singular ...
