An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today.
Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale.

Practical List:
1) Configure timer control registers of 8051 and develop a program to generate given time
delay.
2) Port I / O: Use one of the four ports of 8051 for O/P interfaced to eight LED’s. Simulate
binary counter (8 bit) on LED’s
3) Serial I / O: Configure 8051 serial port for asynchronous serial communication with serial
port of PC exchange text messages to PC and display on PC screen. Signify end of message
by carriage return.
4) Interface 8051 with D/A converter and generate square wave of given frequency on
oscilloscope.
5) Interface 8051 with D/A converter and generate triangular wave of given frequency on
oscilloscope.
6) Using D/A converter generate sine wave on oscilloscope with the help of lookup table
stored in data area of 8051.
7) Interface stepper motor with 8051 and write a program to move the motor through a given
angle in clock wise or counter clock wise direction.
8) Generate traffic signal.
9) Temperature controller.
10)Elevator control.
