Brailify is a project that converts voice input into a refreshable Braille display, providing a cost-effective speech-to-Braille device. The system uses a combination of Python scripts and an Arduino to process voice input, convert it to text, and then display the corresponding Braille characters using stepper motors.

• Description: This script acts as the firmware for Brailify, handling all major functionalities, including:
  • File Application:
    • Recording and saving transcriptions.
    • Deleting files.
    • Navigating stored files.
  • File Format: Each file is stored as a JSON object with the format { "0": "..." }.
  • Telegram Integration:
    • Fetches messages from a Telegram bot.
    • Allows anyone to send messages to the Brailify user.
    • The Brailify user can send replies as voice messages.
  • User Inputs & Outputs:
    • Handles push buttons for navigation.
    • Controls buzzer and vibration motor for feedback.

• Description: The Arduino code responsible for controlling the stepper motors and joystick.
  • Braille Display Mapping:
    • Implements a 5-window string-to-motor-step mapping system for displaying Braille characters.
  • Joystick Control:
    • Allows users to navigate through transcriptions using the PS2 joystick module.

• Using systemd manager : create active.service file and add configuration for running the active.py script in the background.

sudo systemctl daemon-reload
sudo systemctl start active.service
sudo systemctl status active.service
