CHAPTER 3
METHODOLOGY
In this section discussed how research is done in Chapter 2 can applied in this
system to control door lock system via SMS. There are two important part to be taken
into consideration to make this system will smooth operated. These part were be divided
in the hardware development and the software development. The further explanation for
the both of parts were be discussed in the below.
3.1 Hardware development.
Hardware development will be explain how to design concepts and circuits to be
made to control this system. normally, some things need to be considered as a way to
make the system more complex and also reduce the cost of making these systems. The
further information will be described in the below.
