My brother is in PEC Chandigarh, so I think I can answer your question.
PEC's clubs are very active and helpful. These clubs continue to do something or the other all the time.
Moving on to the robotics club, this is a fantastic club that teaches how to build various types of bits and automation projects using Arduino, Raspberry Pi, and other sensors. You can participate in its annual tech event, and it is quite amazing and the prizes are really good.
Clubs in PEC like IEEE, ROBOTICS are mostly based on CSE branch students. By participating in events you can improve your CV and can enhance your skills. It will be really helpful for you in the future.
