Write your own LED program

Modify the program to do something different, such as:

• • • Blink at a different rate

    • Changing the delays and adding more digitalWrite( ) commands to send some sort of message

    • Think about this...
      You can use the LED to send any communication ever transmitted in the history of communication.
      Just need a protocol that the sender and receiver agree to

• Make your program blink a message in Morse code.
  Example: SOS (Emergency) : short-short-short-long-long-long-short-short-short

  • 1. • You can use "Variables" to store the various durations needed for Morse code.
         Refer to Representation, timing, and speeds

       • You can use "My blocks" to  create functions for the "dot"  (short) and "dash"  (long)  blinks

• Your ideas?

• Here's one way to do SOS, but try it yourself before opening: blink_SOS.mp

Save your program

• Use Project ... Save As to save your program

• Mind+ projects have the extension .mp3

• Each student will use the same computer throughout the week so you can access your saved programs
