Hi,

There are so many options for you to proceed. But I will keep it brief -

• Raspberi pi- start studying it. Start practicing it.
• VLSI - This is having a great scope.
• Robotics

Also First, learn a little bit of C Language, then practice C programming. Then update the C language and practice programming. Learning the entire C language first then practicing C programming will not work.

1. Understand C language.

2. Practice C programming

3. Electrical Fundamentals - Sharpening the SAW

4. Analog Electronics - Do simple experiments.

5. Digital Electronics - Become an Expert.

6. Digital Communication

7. Networking - Learn Slowly but steadily

8. Use Linux Operating System

9. Understand Linux Internals.

10. Buy a Microcontroller kit (ARM-based) and practice Embedded programming on that.

These are some valuable points from side which I think will help you to entering in core field.

Hope this helps.

All the best.
