Circuit Documentation

Summary

This circuit is designed for medical data gathering using an Arduino UNO R4 WiFi microcontroller. It interfaces with a Heart Pulse Sensor and an AD8232 Heart Rate Monitor to collect and transmit heart rate data. The Heart Pulse Sensor's signal is read from an analog pin, while the AD8232 Heart Rate Monitor provides additional heart rate data through its output pin.
