Draws an ECG-like waveform from analog input A0 on a 128x64 SH1106 OLED using U8g2. Shows numeric Pulse (BPM) and SpO2 (%) on a 16x2 I2C LCD. Streams values over Bluetooth via an HC-05 module. Samples ...

We have developed a low-cost heart rate monitoring system that provides real-time feedback on the user's heart rate. The system uses a MAX30102 sensor to detect the user's pulse and calculate their ...

This project implements AI based cardiovascular disease prediction from the ECG waveform along with vital parameters like SpO2 and pulse rate. Arduino UNO R4 WIFI is the central microcontroller which ...

In this digital age, we come across LCDs all around us from simple calculators to smartphones, computers and television sets, etc. The LCDs use liquid crystals to produce images or texts and are ...

LilyGO has launched a fair amount of ESP32 boards with some less common features like Ethernet and OLED Display, cellular connectivity, LoRa & GPS, PoE, watch form factor, and more. Their latest ...
