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 ...
// ESP8266 → Arduino (voltage divider on Arduino D2 → ESP RX!) // D2/GPIO4 (ESP RX) → Arduino D2 via 1kΩ + 2kΩ divider // D1/GPIO5 (ESP TX) → Arduino D3 direct #define BT_RX_PIN 4 // HC-05 TXD → ...
ECG, which stands for Electrocardiogram, is a medical test that measures the electrical activity of the heart over a specific period. The test is commonly known as an EKG (Electrocardiogram) in some ...
Just when you thought you’d seen an Arduino do everything, [birdyberth] built an Arduino powered Electrocardiogram (ECG or EKG). Electrocardiography is a non invasive method of studying the heart. For ...
Abstract: This project uses some sensors and Arduino to design and implement the Affordable Smart ECG Monitoring System. ECG monitoring is now becoming part of everyday life. Through ECG ...
