Arduino HID Emulator

arduino-hid-emulator is a Python library designed to control HID devices (keyboard and mouse) emulated using Arduino. The library allows you to send commands to control mouse movements, key presses, and mouse button actions, as well as perform calibration for precise positioning.

Features

• Mouse Control:

  • Direct movement by specified offset.
  • Smooth mouse movement using a Bézier curve.
  • Press, release, and click mouse buttons.

• Keyboard Control:

  • Press and release keys.
  • Simulate key combinations (e.g., Ctrl + C).

• Calibration:

  • Automatic calibration of mouse movement factors for precise positioning.

• Flexibility:

  • Adjustable minimum and maximum duration for mouse movements.
  • Easy connection and control via serial port.

Installation

Ensure Python 3.x is installed on your system, then install the library using pip:

pip install arduino-hid-emulator

Requirements

• Arduino with HID support (e.g., Arduino Pro Micro or Leonardo).
• Upload the Arduino sketch (hid_emulator.ino) located in the arduino/hid_emulator directory.
• Python libraries:
  • pyserial
  • pyautogui

Quick Start

1. Connect Arduino: Upload the hid_emulator.ino sketch to your Arduino board and connect it to your computer via USB.

2. Create a connection object:

   from arduino_hid_emulator.arduino import ArduinoConnection
   from arduino_hid_emulator.mouse import MouseController
   
   arduino = ArduinoConnection()
   mouse = MouseController(arduino)
   

3. Usage example:

   # Move the mouse to a specified point
   mouse.move_direct(100, 100)
   
   # Smoothly move the mouse to a specified point
   mouse.mouse_move(500, 500, duration_min=1000, duration_max=2000)
   
   # Click the left mouse button
   mouse.click("left")
   

4. Close the connection:

   arduino.close()
   

Calibration

For precise movement, it is recommended to perform calibration:

mouse.calibrate()

Calibration is performed automatically, adjusting mouse movement factors.
