ECG Signal Analysis

Introduction

This experiment demonstrates how to measure and analyze ECG signals using a sensor and an Arduino.

Components Needed

• ECG Sensor (e.g., AD8232)
• Arduino
• Electrodes
• Jumper Wires

Circuit Setup

1. Connect the ECG sensor to the Arduino's analog input pins.
2. Place the electrodes on the body to measure the electrical signals from the heart.

The ECG sensor detects the electrical signals produced by the heart and sends them to the Arduino for analysis.

Code for ECG Signal Analysis

Upload the following code to your Arduino to analyze the ECG signal:

const int ecgPin = A0;
int ecgValue;

void setup() {
  Serial.begin(9600);
}

void loop() {
  ecgValue = analogRead(ecgPin);
  Serial.print("ECG Signal: ");
  Serial.println(ecgValue);
  delay(100);
}
            

Explanation

The ECG sensor detects the electrical signals from the heart. The Arduino reads these signals, and the values are sent to the Serial Monitor for analysis.

Troubleshooting

• If no signal is detected, check the electrode placement and ensure they are making proper contact with the skin.
• Ensure that the ECG sensor is connected properly to the Arduino.
