Circuit Documentation

Summary of the Circuit

This circuit integrates an Arduino UNO microcontroller with an AD8232 Heart Rate Monitor. The purpose of the circuit is to measure heart rate signals and process them using the Arduino UNO. The AD8232 module outputs the heart rate signal which is then read by the Arduino UNO for further processing.

Component List

Arduino UNO

  • Description: A microcontroller board based on the ATmega328P.
  • Purpose: Acts as the central processing unit for the circuit, reading sensor data and executing embedded code.
  • Pins: UNUSED, IOREF, Reset, 3.3V, 5V, GND, Vin, A0-A5, SCL, SDA, AREF, D0-D13.

AD8232 Heart Rate Monitor

  • Description: A single-lead heart rate monitor analog front-end.
  • Purpose: Measures electrical activity of the heart and outputs an analog signal.
  • Pins: GND, 3.3v, OUTPUT, LO-, LO+, SDN, RA, LA, RL.

This documentation provides an overview of the circuit components, their purpose, and how they are wired together. The code section includes the initial setup for the Arduino UNO, which will be used to process the heart rate signal from the AD8232 module. Further implementation details should be added to the code to handle the signal processing and any other required functionality.
