ESP32 Electrocardiogram Project

---

Description:

This project involves the development of an electrocardiogram using the ESP32 microcontroller. The device captures the heart's electrical signals and displays them in real-time through a graphical interface. It has been implemented using the Visual Studio Code development environment with the PlatformIO plugin, which facilitates programming and project management.

---

Features:

• Signal Capture: The ESP8266 and the pulse meter AD8232 records the heart's electrical signals through electrodes connected to the patient.

• Real-Time Processing: The captured signals are processed and displayed in real-time on the OLED display.

• MatLab Processing: To ensure a clean representation of ECG data, both manual Fourier transformation filtering and implementation of a bandpass filter using Matlab were performed.

---

Technologies Used:

• ESP8266: Low-power microcontroller with WiFi and Bluetooth connectivity, ideal for IoT applications.

• Visual Studio Code: Powerful development environment with support for multiple programming languages.

• PlatformIO: Visual Studio Code plugin that simplifies development and project management on microcontroller platforms like Arduino, ESP32, etc.
