Use all of the tools at your disposal to send a Morse code SOS message with lights and sounds. When times get desperate in deep space, you want any possible audience to receive your message!
The code in the editor below already works Just plug in your Code Rocket and press upload to see what it does! Tinker with it and make changes to see what each line of code controls.
Watch the videos for line-by-line explanation of how the example program works. Then you'll be ready to make some changes of your own!
These are the new code concepts covered in this example program. To become a great coder, read through these concepts to learn new vocabulary.
New Concept: Speed, revisited
You’ve already experienced the power of speed in your programs. Here, you can see how a program can allow you to basically do two things at once: play your message on the speaker and the LED light at one time. If you do the challenge, you’ll see that as long as you don’t add any extra delays to the program, you can add in more functionality and make the program still look like everything is happening at the same time.
New Concept: Combining programs
Combining programs is not always an easy task. With so many details like where the curly braces go, ensuring you don’t delete a semicolon, and keeping the logic straight, there is much more to combining two programs than simply ‘copy, paste’. If you want to combine programs, it’s recommended that you upload the partially completed project a few times to Code Rocket to ensure you’re not creating errors that will overwhelm you later. It’s no fun to try an upload and find 50 errors!
