Morse Code Light
Convert International or Wabun Morse code into real light signals.
Use screen brightness or a supported phone camera light to transmit the selected Morse system visually in real time.
The Morse Code Light Translator lets you choose International Morse for Latin text or Wabun for Japanese kana. It works on desktop and mobile devices for learning, signaling, emergency communication, and experiments.
Features
Screen Flash Morse Code
Transmit Morse code by switching the full screen between light and dark. Screen Flash is available without camera permission.
Camera Light Morse Code
On supported browsers and devices, use the rear camera light to send the same Morse timing. The tool checks Torch capability before playback and releases the camera when playback stops.
Real-Time Dual-System Conversion
Choose International for Latin letters, numbers, punctuation, and common symbols, or Wabun for Japanese kana. The same Morse sequence can represent different characters in each system.
Adjustable Speed
Control the transmission speed in WPM for slower learning or faster practice.
International and Wabun Support
Both systems use the same Player outputs. The selected system controls text encoding and Morse decoding; it does not change signal timing.
Mobile Friendly
Use Screen Flash in modern mobile browsers. Camera Light appears only when the browser and hardware expose controllable Torch capability.
Privacy First
Conversion runs locally in your browser. Camera access is used only to check or operate Camera Light, and the media track is stopped after checking or playback.
