# Electric Stethoscope

This project is a simple electric stethoscope that can be used to listen to the body sounds of a patient. Prepared for AGU SAPA capsule final project.

## Pre-requisites

### Hardware

- Arduino Uno

- 2 wire electret microphone

- Doctor's stethoscope

- Resistors

  - 1 x 1kΩ

  - 1 x 4.7kΩ

  - 2 x 10kΩ

  - 1 x 22kΩ

  - 1 x 100kΩ

- Capacitors

  - 2 x 10nF (Connected in series for 5nF)

  - 1 x 47nF

  - 1 x 1uF

- 1 x Low-Noise Operational Amplifier (NE5532, TL072, etc.)

- Breadboard

- Jumper wires

- Optional:

  - Soldering iron and its accessories

  - Pertinax board to solder the circuit (or you can simply buy a PCB)

  - 3D printer to print the box for the circuit

### Software

- Arduino IDE

- LTspice

- Python 3.6 or higher

## Running the project

- Clone the repository

- Connect Arduino Uno to your computer

- Build the circuit following the [circuit diagram](https://crcit.net/c/c403772aff41427b846746d022f3cfba)

- Connect circuit to Arduino Uno

- Open the Arduino IDE and upload the `arduino/arduino.ino` file to the Arduino Uno

- Run Python server by running the following commands:

  ```bash

  cd app

  pip install -r requirements.txt

  python main.py

  ```

- Enjoy!
