Heart Rate Sensor

The Heart Rate Sensor project demonstrates how to use a heart rate sensor module with an Arduino Mega to measure and display the user's heart rate in beats per minute (BPM). The heart rate sensor module outputs an analog voltage proportional to the heart rate, which is then processed by the Arduino to calculate and display the BPM on the Serial Monitor.
