The aim of this project is to design and implement an Irreversible Boost Converter as an educational model for understanding the core principles of asynchronous (non-isolated)

An RP2350 UART driver written entirely in ARM Assembler.

Assignments of UOM's EN3240 - Embedded Systems Engineering module

一台 8 位 RISC 微型计算机

An RP2350 UART driver written entirely in RISC-V Assembler.

Passive system for detecting and monitoring FPV drones and UAVs through radio-frequency signals. It scans analog video channels, analyzes signal strength, and generates alerts when a transmission is detected or lost.

Serial terminal + real-time data acquisition for embedded dev: live plots, triggers/alerts, logging, and remote session sharing.

Custom 8-bit 65C02 breadboard computer with hand-written 6502 assembly programs.

4CS016/UM1 - Embedded Systems Programming: A university project on Tinkercad, mostly focused on my experiments using Arduino and real-life simulations.

Multifunctional 3-in-1 Arduino robot (CRAB BOT) that can operate as an RC car, follow objects (object following), and avoid obstacles automatically (obstacle avoider).

AI-powered robotic arm for automated biomedical waste segregation using ESP32, Computer Vision, Embedded Systems, and AI.

Intelligent LPG gas leak detection system on ESP32 with ML-based early detection, OpenAI alerts, MQTT publishing, local web dashboard, Telegram notifications, and OTA updates

"Interrupt-driven color-sorting conveyor on ARM Cortex-M33 (EFM32PG28)"

The Physical Kill-Switch Protocol for Autonomous Robotics & AI Systems. Shifting AI safety from software guardrails to hardware-level finality.

Arduino-based smart door lock system using RFID authentication, servo motor control, LCD feedback, LEDs, and buzzer alerts for secure and automated access control.

This portfolio showcases my previous work in PCB design and fabrication. It includes pictures of various PCBs that I have designed and fabricated using Altium tool.

Arduino-based electronic Ludo dice using 7 LEDs, random dice generation, push-button control, and buzzer feedback.

An Arduino-based system that autonomously detects and tracks flames via IR sensing, locks a servo-driven nozzle to the flame's position, and activates a water pump for targeted suppression — minimizing collateral damage over conventional sprinklers.

Embedded AVR Assembly project for SpO2 monitoring using ATmega32. Includes Proteus simulation, LCD interface, EEPROM storage, sensor data processing, and hardware implementation.
