Working with Servomotors
In this project, you will use the ARM's timers and interrupts to create a PWM signal capable of driving a servo motor. Servo motors are typically used to set and hold a position within a limited arc - for example, electronically controlling the steering of an RC vehicle. Continuous-rotation servo motors are also available. These use the same PWM control signals, but since they rotate continuously (instead of in a confined arc like a regular servo), they can be used as drive motors for simple vehicles like RC cars.
