The problem RFID door lock using Arduino and servo motor (ES) solves

The project that we will be working on is an RFID door lock that will be available to
the general public at an affordable price. The goal of this project is to create a more
convenient way to unlock your door than the traditional key. In the key’s place is an
RFID tag that will unlock the door by proximity. However, the improvements of this
RFID door lock must outweigh the complications of implementation. The list of
customer needs (in the Requirements and Specifications section) was constructed with
that fundamental goal in mind. The design consists of two components. The first
component is the actual door lock that must be installed in the doorframe. This will be
controlled by a magnetic lock and will need to be powered. The second component is a
relatively small module that you can install anywhere near the door. This module is
responsible for the RFID sensing. Chapter 2 goes over the requirements and
specifications determined for the RFID door lock. The requirements are inspired by
surveys of various groups as well as personal interest. The specifications are designed
in order to meet these requirements. These are created before the actual design of the
RFID door lock had been created so the requirements and specifications may not
exactly meet the final product. However, the final product is still designed with these
ideas in mind. In the Functional Decomposition (Chapter 3), the design of the final
product is shown and explained. This chapter also documents the tests and
complications confronted throughout the design. The design is split into 5 modules
which were tackled individually until finally bringing the whole product together. The
necessity of each module is included.
