Computer Interfacing
Input/Output Devices
,Introduction
• This session explores the different methods for interfacing with
output devices
• Output devices have a lot of varieties, they basically take data from
computer
• Many output devices have specific communication protocols,
however, we focus here on most commonly used devices
• We also shed light on concepts useful and extendable to other
applications
, Introduction
• In this session we focus on:
• Multiplexed LED displays
• Alphanumeric LCD displays
• Graphical LCD displays
• Moreover, we look at
• Using relays
• Control of stepper motors
