What is Embedded Systems?
An embedded system is a small computer system designed to perform a specific task inside a device or machine. It combines hardware and software to control and manage operations efficiently. Unlike normal computers, embedded systems are built for dedicated functions such as monitoring, controlling, or automation. Examples of embedded systems:
- Washing Machine
- Smart TV
- Car ABS System
- Microwave Oven
- Traffic Light Controller
- Smartwatch
Main Components of Embedded Systems
1. Microcontroller
Acts as the brain of the system.
2. Memory
Stores program data and instructions.
3. Input Devices
Sensors, switches, and keypads provide input.
4. Output Devices
LEDs, motors, displays, and buzzers produce output.
5. Embedded Software
Software written mainly in C or C++ controls the hardware.
How Embedded Systems Work
- Input devices collect data
- Microcontroller processes the data
- Software makes decisions
- Output devices perform actions
Example:
A temperature sensor detects heat and automatically turns ON a cooling fan.
