This course provides a foundational understanding of embedded systems with emphasis on 8051 and ARM architectures. Students learn microcontroller programming, interrupt handling, peripheral interfacing, and communication techniques. The course integrates theory with hands-on laboratory practice using modern development tools to design and debug basic real-time embedded applications

Course Outcomes: After successful completion of the course, students will be able to

• CO1: Explain the fundamentals of embedded systems, microprocessors, microcontrollers, DSPs, and 8051 architectures.
