Mini Project Assistance & Hands-on Training

Mini projects are the perfect way to start building confidence with hardware, coding and real-world problem solving. At Beltric Labs, we help you pick the right project, understand every connection and line of code, and complete it in a structured way so you’re ready for viva, demos and future internships.

You can choose from Electronics-only projects, IoT-based projects, or Python/OpenCV-based projects. We’ll guide you from basic theory and circuit understanding all the way to a working prototype and project report.

What You Get in Mini Project Support

A complete hand-holding experience to finish your mini project with clarity, confidence and working hardware.

  • Help choosing a project that matches your semester, skills and deadline.
  • Full explanation of circuit diagrams, components and sensor working.
  • Guidance with coding (Arduino, ESP, Python, OpenCV as applicable).
  • Debugging support for common hardware and software issues.
  • Help in structuring your report, block diagrams and flowcharts.

Electronics Mini Projects (Sample List)

These projects focus on basic electronics, sensors and transistor/IC-based circuits. We’ll help you understand each component and its role in the circuit.

  • Automatic Street Light – LDR + transistor-based ON/OFF system.
  • Digital Temperature Display – LM35 sensor with 7-segment display.
  • Touch-Based Switch – Simple capacitive touch to control LED or relay.
  • Water Level Indicator – Multi-level indicator using transistor ladder or IC 555.
  • Burglar Alarm System – IR/LDR-based alarm with buzzer.
  • Dark/Light Detector – LDR-based automatic night lamp.
  • Fire Alarm Circuit – Thermistor-based heat detection.
  • Smart Fan Speed Controller – Temperature-based DC fan speed control.
  • Obstacle Detection Circuit – IR transmitter + receiver pair.
  • Automatic Room Light Controller – LDR + relay controlling a bulb.

You can pick from these or share any similar mini electronics idea and we’ll check its feasibility with you.

IoT Mini Projects (Sample List)

These projects use ESP32/ESP8266, basic sensors and mobile/cloud platforms such as Blynk, MQTT or Thingspeak.

  • IoT Controlled LED – Control LED from mobile using Blynk or MQTT.
  • Smart Home Automation – Control fan/light via phone using ESP + relay.
  • IoT Weather Station – DHT11 + ESP posting data to Thingspeak.
  • IoT Door Lock – RFID + ESP + Blynk for basic access control.
  • Motion Alert System – PIR sensor sending alerts (Blynk/Telegram).
  • IoT Smart Dustbin – Ultrasonic sensor + servo for auto lid.
  • IoT Gas Leak Detector – MQ2 sensor with mobile alert.
  • IoT Parking Slot Indicator – Ultrasonic sensors showing free/occupied slots.
  • IoT Light Control Based on LDR – Auto + manual app control.
  • Temperature & Humidity Monitor – DHT11 + OLED + Blynk dashboard.

If your college suggests any similar IoT topic, we can adapt and customise it to your syllabus and time.

Python & OpenCV Mini Projects

Software-focused mini projects using Python for basic AI and computer vision.

  • Face Detection using OpenCV – Webcam-based face detection.
  • Color Object Tracking – Track a specific coloured object in video.
  • Simple Object Detection – Using pre-trained models for basic detection.
  • QR Code / Barcode Scanner – Read QR codes via webcam.
  • Basic Attendance System – Simple face/QR-based attendance logic.
  • Image Filters & Effects – Apply blur, edge detection, grayscale filters.

For Python/OpenCV projects, we focus more on understanding the logic, libraries and how to explain the flow in your viva.

How Beltric Labs Works With You

We don’t just “make the project for you”. We build it with you so you can confidently explain it.

  • 1. Project Selection Call: Short discussion to understand your branch, semester, college requirements and deadline.
  • 2. Finalising the Idea: We suggest 2–3 options and lock one mini project with you.
  • 3. Components / Kit Planning: We help you list or arrange required components. (Kits can be shipped if needed.)
  • 4. Live Build Sessions: Step-by-step live sessions where we build the circuit/code together.
  • 5. Debug & Testing: Help in fixing common issues so the demo works smoothly.
  • 6. Documentation Support: Guidance for abstract, block diagram, circuit diagram, flowchart and basic report formatting.
  • 7. Viva Preparation: Important questions, how to explain the working, and how to present your mini project confidently.
