This project aims to develop an affordable and portable heart rate monitoring device using Arduino Uno microcontroller a pulse sensor, overcoming the limitations of current solutions like fitness trackers medical equipment. Fitness can be costly lack customization, while medical-grade devices are bulky designed for clinical use, making them impractical daily wear. The proposed system integrates Uno, sensor capture data, LED visual feedback, breadboard assembly. processes analog signals from filters noise, calculates beats per minute (BPM), displaying results on serial monitor. provides real-time feedback by blinking with each heartbeat. low-cost customizable solution is well-suited personal tracking, basic health monitoring, educational purposes. It addresses need more accessible alternative high-priced professional devices, offering portable, user-friendly option. Future developments could include adding wireless connectivity, data storage, advanced algorithms improve accuracy. Ultimately, this showcases how open-source technologies offer scalable, benefiting diverse range users
