      💡 Tips & troubleshooting
      

        
    
          
  • Browser: Web Serial only works in Chrome / Edge.
    • 
          
  • "Already open" error: close PlatformIO/Arduino monitor first — only one app can hold the port.
    • 
          
  • Wrong baud: match monitor_speed in platformio.ini (project default: 115200).
    • 
          
  • Garbled output: wrong baud → garbage characters. Try other rates.
    • 
          
  • No output, no error: the chip might not be running. Hit physical RESET on the board.
    • 
          
  • Want to flash? Disconnect first, then go to flash.html.
