This document provides a detailed overview of a heart rate monitoring circuit that utilizes an Arduino Nano microcontroller in conjunction with an AD8232 Heart Rate Monitor module. The circuit is designed to capture heart rate signals and process them through the Arduino Nano for further analysis or display.

The provided code is a template for the Arduino Nano microcontroller. The setup()
function is called once when the microcontroller is powered on or reset. It is used to initialize the settings, such as pin modes or serial communication parameters. The loop()
function is called repeatedly and contains the main logic of the program. It is here where the Arduino would typically read the heart rate signal from the AD8232, process the data, and perform actions such as displaying the heart rate or sending the data to a computer for further analysis.
Note: The actual implementation code for reading and processing the heart rate signal is not provided in this document and should be developed according to the specific requirements of the application.
