This MorseCode app represents characters (data) as symbols in Morse Code.

Text messages can be created and listened to; just as a telegraph operators would have heard them at the turn of the 20th Century. They can also be exchanged between connected Kookaberries.

Step 1: Setup

Listen

Connect a Buzzer to P1 on the back of the Kookaberry. This will sound out the morse code messages.

Transmit and Receive

To allow two Kookaberries to send morse messages to each other, connect them together with a 3 pin JST lead. Connect P1 on the transmitting Kookaberry to P2 on the receiving Kookaberry.

Step 2: Running and using the app

Navigate to the MorseCode app and press Button B to run. There  are four modes controlled by successive presses of Button B. These are

Home Screen

This is where  all the letters in the alphabet, plus numbers 0-9 and a space, together with their equivalents in morse code, are shown. NOTE: the space between words is represented by “/” on the Kookaberry’s screen.

Pressing Button D sends the code of the character selected to Pin 1. The transmit trace (Row 5) will show the pulses corresponding to the dots and dashes of code of the character selected.
