Projects

Smart Home Assistive Technology System

ESP32-based embedded control system with multi-sensor integration

Developed an ESP32-based embedded control system integrating PIR, light, temperature, and gas sensors with actuators to automate lighting and environmental monitoring. Programmed C++ control logic managing real-time sensor-to-actuator response across multiple hardware subsystems. Tested and debugged hardware/firmware interactions to confirm reliable sensor readings, actuator behavior, and system stability.

MATLAB & Simulink Motor Control Simulation

DC motor control and feedback system analysis

Modeled DC motor control behavior in MATLAB/Simulink, applying transfer functions and feedback loops to analyze system response. Evaluated dynamic system behavior through simulation to build practical controls knowledge applicable to robotics and physical AI systems.

Bluetooth Assistive Access Device

Wireless embedded device with 3D-printed enclosure

Built a Bluetooth-enabled embedded device with custom 3D-printed enclosure, taking a wireless system from firmware to physical housing. Implemented embedded control logic managing sensor input and wireless communication; validated through iterative testing. Extended this hardware-design approach in related projects prototyping additional low-cost assistive-device concepts.

Embedded Sensor Monitoring System

Real-time sensor acquisition and actuator control pipeline

Developed firmware processing real-time sensor acquisition and driving system outputs from live data, implementing a perception-to-action pipeline core to physical AI and robotics applications.
