3.1 Introduction

The purpose of this chapter is to introduce a number of topics dealing with a mechatronic system.
This starts with an overview of mechatronic systems and a look at the input and output signals
of a mechatronic system. The special features of microprocessor input and output are next.
Software, an often-neglected portion of a mechatronic system, is briefly covered with an emphasis
on software engineering concepts. The chapter concludes with a short discussion of testing and
instrumentation.
