09 Mission Instructions
Your mission is to create a mobile emergency alert robot. Use a button as an input and a buzzer (or LED -- you choose!) as the output to deliver your mobile emergency message.
Humans have been searching for new and more efficient methods of communication for all of recorded history.
In the 1800s, the invention of the telegraph allowed people to send electric signals across greater distances than ever before. These telegraphs only allowed operators to send electronic pulses (like beeps or taps) — no voice or video calls for them!
In order to send useful information in this way, they invented Morse code, an alphabet made up of short and long pulses.
Even today, with many more sophisticated methods of technology, Morse code remains a simple way to communicate in emergencies. The short and long pulses can be transmitted as blinking lights, audio tones, or dots and dashes written on paper (or drawn in the sand on a desert island!). The code for SOS is recognized internationally.
