Morse-It sends text as Morse code using the screen, sound and the device flashlight where supported. ## At a glance ![Morse-It: encoding text as a light-signal sequence](https://gamemechanics.pro/images/mechanics/flash-morse-encode.webp) [Morse-It](https://apps.apple.com/us/app/morse-it/id284942940?uo=4) · © Francis Bonnin.

Two dots and a dash represent the current light-code symbol - Limit flashing frequency and offer sound or a static code representation. - [Morse-It](https://apps.apple.com/us/app/morse-it/id284942940?uo=4) ## How it works The lights and pauses become a sequence to be created or read. ## Variants ### Variants and applications - Short and long signal. Action: Transmit two distinguishable types of activation. Application: Binary response, simple commands to a friend, signal training. Requirements: Rear LED and app control. Conditions: The person can read light; The automatic recipient needs a camera or photo sensor. - Code number of inclusions. Action: Transmit the number in separate pulses. Application: Door number, selecting an answer option, indicating the number of items. Requirements: Rear LED and control from the application. Conditions: Separate messages with a long pause so as not to confuse adjacent numbers. - Morse code. Action: Encode characters with dots, dashes and pauses. Application: Spy quest, communication trainer, short phrase exchange. Requirements: Rear LED and app control. Conditions: This is a training or gaming connection, not a guaranteed emergency channel. - Password from durations. Action: Enter a sequence of different holds. Application: Open the virtual lock, repeat the character's knock. Requirements: Rear LED and control from the application; Software game rule. Conditions: Recognize input duration; LED serves as physical confirmation. - Password from pauses. Action: Maintain equal pulses by changing the intervals between them. Application: Secret rhythm, time puzzle, musical phrase. Requirements: Rear LED and app control; Software game rule. Conditions: Estimate intervals with tolerance rather than requiring perfect milliseconds. - Repeat the shown rhythm. Action: The application or partner shows the drawing; the player plays it. Application: Memory game, light “Simon”, learning to count. Requirements: Rear LED and control from the application; Software game rule. Conditions: The original sequence can additionally be shown with text or sound. - Getting on the beat. Action: Turn on the lights at specified moments in the music. Application: Rhythm playing, performance, group score. Requirements: Rear LED and app control; Software game rule. Conditions: Evaluate the command time and separately take into account the delay of the actual light. - Reaction to a signal. Action: Turn on or turn off after a valid signal, ignoring a false one. Application: Training of gaming attention, duel for reaction. Requirements: Rear LED and control from the application; Software game rule. Conditions: The competition requires the same delay and device rules. - Action in a window of time. Action: Keep the light only in the allowed phase of the cycle. Application: Go through a virtual patrol, activate the rotating mechanism. Requirements: Rear LED and control from the application; Software game rule. Conditions: Phases are set by the game; the real flashlight does not detect the patrol. - Delayed playback. Action: Record the light sequence and run it later. Application: Asynchronous riddle, light cue, repeat of the author's drawing. Requirements: Rear LED and control from the application. Conditions: Record commands and intervals; playback does not promise accurate optical synchronization. ## Context and limits Author's working classification for designing games and interactions. Options can overlap and combine; the list is not a generally accepted standard or proven exhaustive list. Application examples are conditional unless a specific verifiable observation is indicated nearby.
