Final year project ideas for BTech students
As a student, it’s easy to get caught up in lectures, assignments, and exams. But employers today look for one extra thing: your practical experience.
Building mini-projects not only sharpens your technical skills but also boosts your resume and confidence. Whether you’re from CSE, Mechanical, Civil, ECE, or any other branch — the right projects can give you a major advantage.
In this article, you’ll discover 20 practical and impressive mini-project ideas you can build before your final year. Let’s dive in!
1. CSE: Personal website with interactive resume.
Each Computer Science student should graduate with an individual portfolio. Rather than providing a bland résumé, having your own website demonstrates your abilities in a dynamic and original approach. It also has a significant impact on recruiters.
You will design a simple website that includes your name, image, bio, talents, certifications, projects and a contact page. You can also include an interactive resume page that allows viewers to browse or download your résumé. Small animations created with CSS or JavaScript can be included to make it more appealing.
As you work on this project, you will learn HTML, CSS, JavaScript, basic hosting on GitHub Pages or Netlify, and even some UI/UX design concepts. You might even get a basic understanding of SEO, which gets your website listed in Google searches.
To make it stand out, you may incorporate additional features such as a dark mode option, a contact form which instantly records responses into your Google Sheets, and even a rudimentary blog area where you can publish about your projects or learning processes.
Visual Studio Code will be a good alternative for coding, while GitHub, Canva for images, or Figma for developing layouts will be highly helpful. This project will demonstrate your technical abilities, sense of design, and capacity to complete and host a real-world product, which will be incredibly appealing to companies.
Begin by sketching up a basic layout for your website on paper or using a program like Figma. Then develop one area at a time: Home, About, Projects, Resume, and Contact. When finished, publish it online and proudly put the link in your LinkedIn, résumé, and email signature.

Pro Tip: Include a “Download Resume” button and track how many people click it using simple analytics. This small feature proves that you care about user experience!
2. Mechanical: Automatic Solar Tracker for Solar Panels.
Solar panels function best when exposed directly to sunlight. However, because the sun travels over the horizon, the panels must be oriented to maximize power generation. A solar tracker resolves this issue by tracking the sun’s movement throughout the day.
In this project, you will create a miniature model in which a solar panel or light sensor moves autonomously towards a source of light. You may accomplish this by using simple components such as Light Dependent Resistors (LDRs), small DC motors, and a basic microcontroller like Arduino.
This project will teach you vital skills in mechanical design, rudimentary electronics, and computer programming for automation. You will also gain practical knowledge of renewable energy technologies, which are becoming increasingly valuable these days.
If you want to improve your project even more, you can build a dual-axis tracker that moves horizontally and vertically. You can also include an LCD display to show real-time voltage output or store energy data on a memory card for later examination.
You will need some basic tools for coding, such as the Arduino IDE, a soldering kit, and, if you want to develop custom components, a 3D printer. This project makes a valuable contribution to your portfolio because it demonstrates your ability to combine mechanics, electronics, and programming into a single solution. It may lead to internships and job possibilities in green energy companies and research labs. Even simple online simulators such as Tinkercad can assist you in testing your circuit virtually before you construct the actual one.
Begin by learning how LDR sensors operate and how to control motors using Arduino. Create a small prototype that follows a light source, such as a torch. Once you have a strong understanding of the fundamentals, connect it to a small solar panel and compare the energy gains to a stationary panel.
