What is an embedded system..??
An Embedded System can be defined
as a computer system designed to
perform specific function.
It bring together
software, hardware, and mechanical
parts with either fixed or
Requirements for embedded system
as our requirement
EMBEDDED SYSTEM IN DAILY LIFE
Moving message display Digital clock
DVD player Traffic Light
Micro controller is used to control
the operation of various machines
and devices according to the
Pin’s of 8051.
ALE / PROG
EA / VPP
Intel introduced 8051, referred as MCS- 51, in
The 8051 is an 8-bit processor
The CPU can work on only 8 bits of data at a time
The 8051 became widely popular after allowing
other manufactures to make and market any
flavor of the 8051.
4K bytes ROM
128 bytes of on-chip Data RAM
32 bidirectional and individually addressable I/0 lines
Two 16-bit timer/counters :T0 and T1
On-chip clock oscillator
3-terminal positive voltage regulators
Xx- output voltage (7805 +5v, 7812 +12v,)
Output current is 1.0A
Uln 2003/2803 series
• This is 7/8 channel inductive load driver IC.
• Made up by Darlington transistor pair b/w
• This IC can only sink but not source.
motor can’t drive
This showes that this IC can only sink but not source
The L293D is assembled in a 16 lead
package which has 4 center pins connected
together and used for heat sinking.
This device is suitable for use in switching
applications at frequencies up to 5 kHz.
600mA OUTPUT CURRENT CAPABILITY
It is motor driver IC’s.
print “hello world “at lcd
Proteus connection for lcd
Advantages/ Disadvantages of M.C.
Small in size
Programming of MC is simple
Functionality is quite difficult.
Speed ( if you need a response to an input
In less than a few microseconds)
