This document summarizes a project to design a simple ECG monitoring system using an Arduino microcontroller and AD8232 ECG sensor. Electrodes are placed on the left arm, right arm, and right leg of a patient to collect electrocardiogram signals, which are transmitted to the AD8232 module. The module processes the data and sends analog values to the Arduino, which displays the continuous heartbeat reading in the serial monitor. The system allows for low-cost, wireless monitoring of a patient's heart activity from anywhere.
