OLED signal-quality display
Display the active mode, optical signal status, experimental BPM estimate, and AD8232 leads-off state. The display intentionally labels the build education-only and shows no SpO2 value.
What you build in this project
OLED signal-quality display is one focused build from the ESP32 ECG & Optical Pulse 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, DIY-003 OLED, MAX30102, AD8232, 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.
What this project uses
Every item is in the kit — nothing extra to buy.

I2C address and bus inventory
Run the firmware scan command with each module added separately, then together. Confirm the OLED responds at 0x3C or 0x3D and the MAX30102 at 0x57. Record any address or…
MAX30102 raw optical waveform
Use optical mode to stream raw red and infrared samples. Compare no-finger, lightly placed fingertip, firm pressure, ambient-light, and motion conditions. Treat every nu…
Experimental optical pulse interval
Observe how the beat detector estimates pulse intervals only when the infrared signal exceeds a provisional quality threshold. Compare stable and moving fingers and expl…
