このツールについて

Master Morse code with an interactive visual trainer. Browse the full A-Z and 0-9 Morse alphabet chart, then test yourself with flash card mode — see a character and type the correct dots and dashes, or do it in reverse. Choose your speed: Beginner (3 s per card), Intermediate (1.5 s), or Advanced (0.5 s). Progress is saved to localStorage so you can track which characters you have mastered across sessions. Each dot and dash is animated with CSS transitions for a visual timing feel.
