Microcontrollers and Embedded Systems 

• Microcontrollers:
  • Small computers on a single chip that integrate a processor, memory, and input/output peripherals. They are designed for specific tasks like controlling devices, sensors, and actuators in a system.

• Embedded Systems:
  • ​​​​​​​Dedicated systems that perform specific functions as part of a larger system, integrating software and hardware. They use microcontrollers or microprocessors for real-time processing.

 

 

 

In mechatronics engineering, these components are critical for automating mechanical and electronic systems such as robotics, manufacturing processes, and smart devices.
