Arduino Uno Heart Rate Sensor

This project demonstrates how to use a heart rate sensor with an Arduino Uno to measure the user's pulse.

The sensor's analog signal is read by the Arduino and processed to detect heartbeats.

The results are displayed on the serial monitor.

Components Needed

• Arduino Uno
• Heart Rate Sensor
• Jumper Wires
• Breadboard

Block Diagram

Hardware Wiring Explanation:

Connect the Heart Rate Sensor to Arduino Uno:

Connect the heart rate sensor to the Arduino Uno as described in the circuit setup section.

Software (Arduino IDE):

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Uno.

Power the Arduino

Plug the Arduino into a USB port or power it with an external adapter.

Monitor the Output:

Open the serial monitor with a baud rate of 9600.

Place your finger on the heart rate sensor and observe the serial monitor output displaying the sensor values and pulse detection.

Applications

Notes

Ensure the heart rate sensor is correctly connected to the Arduino Uno and powered.

The threshold value for pulse detection may need adjustment based on your specific sensor and conditions.

Modify the code to implement additional features such as calculating beats per minute (BPM).
