Nasal Monitoring System

I am developing a wireless breath monitoring device that uses the BME280 environmental sensor to detect inhalation and exhalation patterns by analyzing subtle changes in temprature near the nose or mouth. I am handling the firmware development, PCB design, and overall electronic system integration of the device. Sensor interfacing and signal processing, WiFi-enabled data transmission, Cloud integration (e.g., Firebase, MQTT, or custom APIs), Power optimization and embedded coding.

Electromyography (EMG) Detection Device

This device is designed to detect muscle activity and strength in the human body by capturing EMG signals. It processes the analog signals generated by muscle contractions and sends the data to a graphical plotter for visualization.To ensure accurate signal conversion, I use an external ADC (ADS1115), which converts the weak analog EMG signals into digital data for further analysis and display.

Landmine Detection Robot using STM32

A landmine detection robot using an STM32 microcontroller works by integrating sensors (like ultrasonic sensor, coil), and user interface interaction to detect landmine with the help of metal detector and using GPS module send the real time location to the user help of the GSM module. And very useful L298N Motor driver to control the wheels.The robot uses a metal detector sensor (inductive coil-based) to identify underground metallic objects that resemble landmines. It also integrates ultrasonic sensors for obstacle avoidance and GPS + GSM modules for real-time location tracking and remote data transmission.

Obstacle-Avoiding-Robot

This project focuses on building an autonomous robotic car capable of detecting and avoiding obstacles using an ultrasonic sensor.The robot uses an ultrasonic sensor (HC-SR04) mounted at the front to continuously measure the distance between the robot and any obstacles ahead. If an object is detected within a predefined range, the robot automatically changes its direction to avoid a collision. A Bluetooth module (HC-05) is also integrated to allow remote control and monitoring using a smartphone or other Bluetooth-enabled device.

Smart Light Control System | Embedded Automation Project.

I have developed another embedded systems project—a Smart Light Control System that combines automation with manual control to improve energy efficiency. The system uses an LDR sensor to automatically adjust LED brightness based on ambient light levels. It also features a manual override with two push buttons to toggle the LED ON/OFF. Real-time data, including light intensity and brightness levels, is displayed on an HD44780 LCD via I2C, and UART communication enables remote monitoring and data logging. Built using an STM32 microcontroller, the project integrates key functionalities such as ADC, PWM, GPIO, I2C, a

Multiple LED Control Using Switch Interrupt with Debouncing

This project focuses on controlling multiple LEDs using a single push-button through interrupt-based input handling.The key challenge addressed in this project is the switch bouncing effect, which is common in mechanical switches and can lead to multiple false triggers. To ensure stable operation, software debouncing logic is implemented within the interrupt handler. Working Principle-When the button is pressed,it triggers an external interrupt,The interrupt service routine (ISR) includes debounce logic (using time delay or flag check) to avoid multiple unwanted triggers.

#Software Debouncing: Implemented using delay or timer-based logic

#Multiple GPIO Outputs: To control multiple LEDs
