Optical Pulse Estimate on OLED
Display an experimental optical pulse estimate and signal-quality status on the I2C OLED. Test modules separately before sharing the I2C bus. Displayed numbers are not validated heart-rate or SpO2 measurements. Educational outline; pin mapping and code require bench testing.
What you build in this project
Optical Pulse Estimate on OLED is one focused build from the Biomedical Sensor & Bio-Signal Learning Kit. It uses the parts listed below to make a working electronics example, then you can combine it with the other projects in the kit.

Parts used
ESP32U, MAX30102, OLED, Breadboard, Jumper wires
What to check
Wire the parts, upload the sketch from the kit page, then test this project by watching the Serial Monitor or the output behavior.
What you learn
You learn how the controller reads real sensor signals, makes a decision in code, and turns that result into a useful output.
