Heartbeat Module

The Heartbeat Module project demonstrates how to interface a heartbeat sensor with an Arduino Mega to detect and monitor heartbeat signals. The heartbeat sensor provides a digital output signal that changes state with each heartbeat detected. This project reads the digital signal from the heartbeat sensor and displays a message on the Serial Monitor whenever a heartbeat is detected.

Components Needed

• Arduino Mega
• Heartbeat Sensor Module

Instructions

Install Required Libraries:

No external libraries are required for this project.

Circuit Setup:

Connect the heartbeat sensor module to the Arduino Mega as described in the circuit setup section.

Code Upload:

Open Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Testing:

Upload the code to the Arduino Mega.

Open the serial monitor in Arduino IDE (set to 9600 baud).

Ensure the heartbeat sensor is correctly positioned and detecting heartbeats.

Observe the Serial Monitor for messages indicating detected heartbeats.

Applications

Notes

Ensure the heartbeat sensor is securely attached to obtain accurate heartbeat readings.

Adjust the delay time in the

Experiment with different sensor placements and configurations to optimize heartbeat detection accuracy.

Calibration may be required based on sensor sensitivity and environmental conditions.
