byk slide

Start Slide on a custom port:

byk slide -p 8080

Typical workflow during a presentation:

# 1. Start Slide on the presentation computer
byk slide -p 8080

# 2. Open the control address on your phone
#    under the same Wi-Fi network

# 3. Enter the access password

# 4. Use the web page to control slides and mouse actions

Notes

• Slide works by simulating keyboard and mouse events. Make sure your environment allows such operations and avoid conflicts with other automation software.
• It is recommended to test locally before a presentation to ensure compatibility with your system, presentation software, and pyautogui.
• For safety, only run Slide when needed and keep the access password secure.
• Slide is designed for LAN usage only and is not recommended for direct public network exposure.
