3. INTRODUCTION TOEMBEDDEDSYSTEMS
• 1. An embedded system is a computer system—a combination of a computer processor, computer
memory, and input/output peripheral devices—that has a dedicated function within a larger
mechanical or electronic system.[1][2] It is embedded as part of a complete device often including
electrical or electronic hardware and mechanical parts. Because an embedded system typically
controls physical operations of the machine that it is embedded within, it often has real-time
computing constraints. Embedded systems control many devices in common use today.[3] In 2009, it
was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded
systems.[4][needs update]

4. HARDWARE
MICRO CONTOROLLER(AT89C51)
LED(Light Emitting Doide)
RS232 Data Interface
LCD
POWER SUPPLY

5. POWERSUPPLY
• 230 AC 50 Hz DC Output
•
• Step Down Bridge Regulator
Transformer Rectifier

6. LIQUID CRYSTALDISPLAY
A liquid-crystal display (LCD) is a flat-panel display or
other electronically modulated optical device that uses the
light-modulating properties of liquid crystals combined
with polarizers. Liquid crystals do not emit light
directly,[1] instead using a backlight or reflector to produce
images in color or monochrome.[

7. microcontroller
• Microprocessors and microcontrollers are widely used in embedded systems
• products.Microcontroller is a programmable device. A microcontroller has a
• CPU in addition to a fixed amount of RAM, ROM, I/O ports and a timer
• embedded all on a single chip. The fixed amount of on-chip ROM, RAM
• and number of I/O ports in microcontrollers makes them ideal for many
• applications in which cost and space are critical.

8. ADVANTAGES
• Less costs for per bit.
• It has not many interconnections.
• It has Better steady and Higher speed.
• It has Higher dependable

9. DISADVANTAGES
• Hard to keep up.
• Hard to take a back-up of implanted documents.
• You need to reset all setting, due to happen any issue in the framework.
• Investigating is Harder.
• Harder to move information from one framework to other framework.
