Talking SWR and power meter with speech output for visually impaired amateur radio operators

A basic full-bridge inverter built to demonstrate the conversion of DC (battery) power into AC (alternating) power using electronic switches and the principles of PWM. (2019-20)

Auto Solar Street Light Controller – LDR and IR-based energy-efficient lighting system with comparator and relay logic (2018-19)

First‑year BTech Electrical Engineering project (2020–21): NI Multisim simulation of a wearable stress‑meter with sensor‑fusion analytics.

Open‑source Si5351 frequency generator powered by ATtiny1614, supporting 3 outputs, calibration, EEPROM, and intuitive menu navigation.

Arduino Inductance Meter shield

Stereo FM / AM Radio Receiver with VU Meter based on the TEA5711 radio IC and dual LM386 audio amplifiers. This project features FM stereo and AM reception, a 10-LED stereo VU meter, custom PCB design, and is intended for educational and non-commercial DIY electronics use.

The Transformer Fault Detection using GSM Module is a real-time monitoring system designed to detect abnormal operating conditions in power distribution transformers. The system continuously monitors key parameters such as temperature, voltage, current, and oil level using sensors interfaced with an Arduino Uno.

Automate relay-based devices with this ESP8266-powered web control system. Set activation times, force on/off instantly, and monitor relay statuses through an intuitive web interface. Streamline device scheduling with ease.

Speed control of DC motor using AT89C51 (Proteus simulation)

Arduino hardware shield to send and receive data from OpenTherm devices

A temperature-controlled fan system using the LM35 sensor for real-time temperature monitoring and automated fan activation based on threshold values.
