The document outlines a mini project on a heartbeat monitoring system designed as an inexpensive and accessible alternative to traditional heart rate monitors, employing components like an Arduino Uno and a heartbeat sensor. The system operates using a photo plethysmograph to detect blood volume changes and provides real-time heart rate data, which can aid in continuous monitoring and early diagnosis of heart-related conditions. Key achievements include portability, reliability, and the ability to integrate with other health monitoring systems.
