Simple Oscilloscope Project

This project implements a simple oscilloscope using Python, allowing you to feed a signal to your laptop via its microphone jack and display the captured signal on its monitor.

Features

• Real-time signal display
• Frequency and amplitude measurement
• Adjustable voltage and time divisions
• Support for sine, triangle, and square waves
• GUI interface with start/stop functionality

Requirements

• Python 3.x
• PyQt5
• pyaudio
• numpy
• matplotlib

Installation

1. Clone this repository:

   git clone https://github.com/Sin-a-H/Python-Oscilloscope
   

2. Install the required packages:

   pip install -r requirements.txt
   

Usage

Run the script:

python3 Oscilloscope.py

Code Overview

The main components of the oscilloscope are:

1. Audio input handling using pyaudio
2. Signal processing and FFT using numpy
3. GUI implementation using PyQt5
4. Real-time plotting using matplotlib

Key functions:

• initialize_audio(): Sets up the audio stream
• update_plot(): Updates the oscilloscope display in real-time
• update_frequency_and_amplitude(): Calculates and displays frequency and amplitude
• update_voltage_div() and update_time_div(): Adjust voltage and time divisions

Limitations

• Maximum amplitude: Limited by the headphone jack specifications (typically up to 1.5V or 2.5V)
• Maximum frequency: Limited by the sound card capabilities (usually up to 48kHz)

Screenshots

The app while running the code, will be as above. The costomed headphone-jack that we made by soldering.
