DIY pulse oximeter project uses Raspberry Pi Pico for heart rate monitoring

A DIY pulse oximeter can now be built using a Raspberry Pi Pico, making it easier to monitor heart rate at home. This project utilizes a MAX30102 pulse oximeter module and an SSD1306 OLED display, providing a simple alternative to expensive medical devices. To assemble the device, users place the components on a breadboard and connect them using jump wires. The setup involves wiring power and data connections, utilizing the I²C protocol for communication between the components. After assembling the hardware, users can install MicroPython and necessary libraries on the Pico. The final step is to run the pulse oximeter script, allowing for personal health monitoring with customizable features.
