Send an SOS Message (using breadboard)
|
Note: This "Sending an SOS Message" activity is equivalent to the one using an LED module rather than a breadboard. Now that we have an LED device wired to our Arduino microcontroller using a breadboard (or directly via an RGB LED module), we can send a message using light signals and Morse code. Morse code is a coding scheme used in telecommunication that encodes text characters as standardized sequences of two different signal durations called dots and dashes. The letter A, for example, is a dot followed by a dash. The chart on the left side below shows the combinations. The Morse code rules we will use for signaling are:
For an SOS ("help") message, an S is three dots, an O is three dashes, and the second S is three dots again.

Add the necessary blocks to spell out "SOS" using Morse Code and the LED. The letters S and O are already provided. Then work on adding your initials using the LED and Morse Code, so the message is "SOS YourInitials". |
