Autonom robotväckarklocka med trådlös basstation - KTH

Abstract
This report describes the theory of how a stepper motor works and can be controlled. The
report also describes the development of a working prototype that fulfills the following three
desired main features:
1. The ability to, with the help of a keyboard, control how many degrees the stepper
motor will rotate with a resolution of at least 1 degree. The stepper motor will also
have the possibility to rotate backwards. The rotational velocity should be adjustable
while running.
2. Have a mode where the stepper motor is rotating continuous with the ability of
changing the step modes. The velocity and rotational direction should also be able to
be adjusted while running.
3. A mode with an unusual implementation of the stepper motor, for example the ability
to play a simple song by generating tones.
The part of the report where the prototype is constructed is written as an argumentative text in
which each choice of component is justified by both the pros and cons. The prototype is lastly
built as a standalone unit to demonstrate that everything works as it should.
