Communication with Light & Sound

Design and build a device that uses light or sound to solve the problem of communicating over a distance

How to tell they’ve got it

Tick these off as you see them — no test required.

Design a device that uses light or sound to communicate over a distance (e.g. string telephone, torch signals)
Build and test the device, identifying what works and what could be improved
Explain how the device uses properties of light or sound to transmit information
