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.
9. Test
You've already run your code a few times while you were writing it, but now try sending a few different messages! Play with your Morse code. If you have a friend or parent nearby, try tapping in your message and see if they can decipher it from your robot accurately.
