Compare ECG and Optical Pulse Timing
Acquire timestamped ECG and PPG samples and use the OLED for status. Discuss sampling and filtering delays when comparing electrical and optical signals. This is not a blood-pressure measurement method. Education only, not for diagnosis or health decisions. Body-connected ECG work requires battery-only equipment disconnected from chargers, mains-powered peripherals and test instruments. Verified wiring and tested code are still pending.
What you build in this project
Compare ECG and Optical Pulse Timing 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, AD8232, 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.
