To verify that the heart rate monitor is working as expected, open the serial monitor at 9600 baud

interfacing with arduino and AD8232

/src/sketch.ino

#include <Wire.h>
#include <AD8232.h>

// Define the AD8232 module
AD8232 heartRate;

void setup()
{
  Serial.begin(9600);   // Initialize serial communication
  heartRate.begin();    // Initialize the AD8232 module
}

void loop()
{
  float heart_rate = heartRate.getHeartRate();  // Read the heart rate value
  Serial.println("Heart rate: " + String(heart_rate) + " bpm");  // Print the heart rate value
  delay(1000);  // Wait for 1 second
}

. You should see values printed on the screen. Below is an example output with the sensors connected to the forearms and right leg. Your serial work should spike between +300/-200 around the center value of about ~500.

Research design and problem addressing

A research problem is a specific issue, contradiction, or gap in existing knowledge that needs to be addressed.
Identifying a research problem involves recognizing something problematic that requires attention, explanation, or a solution.
It is essential to have a well-defined research problem to guide the research process and to contribute to the field of study.
The process of defining a research problem includes:
- Identifying a broad topic of interest.
- Conducting a literature review to understand the current state of knowledge.
- Narrowing down to a specific issue that is under-explored or controversial.
- Formulating the problem into a clear, concise statement or question.
Types of research problems include:
- Descriptive: Documenting certain phenomena or situations.
- Exploratory: Investigating a topic to generate new insights or hypotheses.
- Explanatory: Understanding the causes or effects of certain phenomena.
- Predictive: Anticipating future occurrences based on current trends or data.
- Evaluative: Assessing the effectiveness of interventions, programs, or policies.
Defining a research problem is crucial for:
- Setting the direction and scope of the study.
- Ensuring the research is focused and manageable.
- Avoiding duplication of existing knowledge.
- Making a meaningful contribution to the academic field or practical application.
For more detailed guidance on defining a research problem, resources such as Scribbr's articles can provide step-by-step instructions and examples.
