Projects
1. FPGA Piano Synthesizer (2023)
Developed a digital piano synthesizer using Verilog on a Basys 3 FPGA board. The keyboard inputs were scanned to generate tone frequencies using PWM. A DAC converted the digital signal to analog sound via onboard speaker. A seven-segment display showed notes in real-time. This project focused on clock division, frequency synthesis, and signal filtering using FIR design techniques. Perfectly demonstrates embedded digital signal processing on hardware.
2. Smart Traffic Light System (2024)
An adaptive traffic light controller designed using Verilog on an FPGA board. The system detects real-time traffic density via IR sensors and dynamically allocates signal timing to reduce congestion. Implemented on a Xilinx Spartan-6 board, this project optimized state machine logic to minimize delays during peak hours. It also included a 7-segment countdown timer and UART debugging interface. Designed for scalability to integrate with city-wide traffic control systems.
3. IoT-Based Weather Station (2023)
A low-power environmental monitoring system built with ESP32 and DHT11 sensors to collect temperature, humidity, and atmospheric pressure data. The data was pushed to a cloud dashboard using MQTT protocol and displayed using a custom-built UI. Designed with sleep cycles and solar power integration, the system could run in remote outdoor areas. The project demonstrated skills in IoT communication protocols, low-power design, and front-end data visualization.
2. Gesture-Controlled Robot (2022)
Built a gesture-controlled robot using Arduino Nano, an MPU6050 accelerometer, and RF modules. Hand motion data was interpreted in real-time to control a 4-wheeled robot wirelessly. Implemented with Kalman filtering for smooth motion response. Demonstrated skills in sensor fusion, motion control, and basic robotics.
