Low Tech Communications

For this project, we were instructed to devise a method of communicating over a distance of at least 600 yards.

We chose a simple method using 4 colors and their positions to represent different letters and numbers.
The colors we used were red and green, purple and yellow.

One person would be the sender, while another would be the receiver.
The sender translates his message using the code table, and using the
appropriate colors and arm positions, signals the receiver.

The receiver would observe the sender, and write down the signal.
For speed, translation is done after the entire message has been sent.
