Colors and Numbers
We have created a pool of 30 messages. Each message is assigned a number between 1 to 30. The communication system consists of 3 colored balloons to transmit the message and 2 colored balloons to transmit a beginning and end signal.
Each of the 3 colored message ballons will be assigned a number as follows:
Each of the 2 colored signal balloons will be assigned a signal as follows: If the sender raises the balloons: White = begin message Black - end message
If the receiver raises the balloons: Black = message received White = repeat message
To send a message, the sender will raise the balloons (one at a time) needed to convey the intended message number. The receiver would then match the message number to the message using the code sheet.
