what is Embedded system

What is the embedded system ?

As the name suggest embedded means the system have something is attached here in the electronics embedded system means the combination of the hardware and the software. as the example of the embedded system we can take a fire alarm  which is the one of the best example of the embedded system. and it is connected with the sensors or other peripheral devices which are generally used to perform the a whole task. in the term of the fire alarm here the microcontroller have the fire or smoke sensor are attached which is a transducer which convert smoke or fire mean heat energy into the electrical signal and here the microcontroller program check the condition and then that condition get full filled then that alarm buzzer get start beeping and then that all other devices get activated which is used in the relief on the fire. 

in the embedded system a microcontroller are used which is the programmable device and that device have the perticular program are embedded that perform that specific task. as for we can take a example aurduino uno ,raspberry pi etc .

these microcontrollers are example of the embedded system  that have store the programs and perform the our task through it.

Example of embedded system :

1. in the fire alarm
2. mp3 player
3. mobile phones
4. Dvd players
5. microwave oven
6. Robots
7. washing machine
8. dish washer

Adavantages  of the embedded system

• Easy to use
• Easy to customise
• Easy to program as we required
• low power consumption
• low cost
