The Dual-Wavelength Pulse Oximeter is a wearable device that measures heart rate (BPM) and blood oxygen levels (SpO2) using dual infrared and red LEDs. The device outputs real-time feedback via an OLED display and status LEDs. It is powered by an Arduino NANO ESP32 and uses a MAX30100 sensor for accurate measurements.
