Morse Code

Morse Code is a way to send messages using patterns of short and long signals.

Think of it this way

Tapping on a table sends a message through short taps and long taps. A short tap is a dot. A long tap is a dash. Patterns of dots and dashes stand for letters, so a sequence of taps spells out words.

Explaining morse code by grade level

You can build a simple telegraph to send messages. You tap a button to make short or long clicks. Short clicks and long clicks stand for each letter. A friend hears the clicks and figures out your words.

Homemade Telegraph and Morse Code

Morse Code turns switch presses into patterns of dots and dashes — short and long signals that stand for each letter of the alphabet. When you tap the switch quickly, that's a dot. Hold it longer, and you've made a dash. String those patterns together, and you can spell out full words one letter at a time.
