Simple Barcode Scanner Emulator

A simple Tkinter-based Python GUI to simulate barcode scanning. This tool allows you to enter barcode data and simulate a delay before "typing" the data into an active window, mimicking the functionality of a physical barcode scanner.

Features

• Barcode Input: Enter a barcode to be simulated.
• Delay Control: Specify a delay (in seconds) before the barcode is "scanned."
• Simulated Typing: The application types the barcode into any active input field as if it were scanned.

Requirements

• Python 3.x
• tkinter (usually included with Python)
• pyautogui

Installation

1. Clone the repository (or download the .py file directly):

   git clone https://github.com/BahaaAY/simple-barcode-scanner-emulator.git
   cd simple-barcode-scanner-emulator

2. Set up a virtual environment (optional):

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

   pip install -r requirements.txt

Usage

1. Run the application:

   python emulator.py

2. Using the GUI:

   • Enter the barcode you want to "scan" in the Enter Barcode field.
   • Specify a delay (in seconds) in the Enter Delay (seconds) field.
   • Click Simulate Scan to start the simulation.
   • Switch to the target window (e.g., a text editor) within the specified delay to see the barcode input.

Code Structure

• simulate_scan(): Main function that retrieves the barcode data and delay, then starts a thread to type the barcode.
• type_barcode(): Function that waits for the specified delay, then uses pyautogui to type the barcode followed by an Enter keystroke.
• Tkinter GUI: Provides an interface for entering barcode data and delay time.

Example

1. Run the application.
2. Enter 1234567890 as the barcode data.
3. Enter 2 as the delay.
4. Click Simulate Scan and quickly switch to the target window (e.g., a text editor).
5. After 2 seconds, 1234567890 should be typed into the active window, followed by pressing Enter.

Notes

• Ensure that pyautogui is granted permission to control the keyboard if you’re on macOS or any system with strict security settings.
• To stop the simulation while it's running, simply close the application window.
