What are we going to do?
In this activity we are going to learn a bit more bout micro:bit's radio communication
- Understand how to use the Radio blocks to send and receive data between micro:bits
- Understand the specific types of data that can be sent over the Radio
At the end of this activity, we'll be able to send and receive data via radio between two micro:bit boards. We'll use morse code to send data, so first we'll have a look at the morse code.
Now it's your turn!
Now it's time to start using this awesome code to send some secret messages! Do you accept this challenge?
- To send a secret message, first choose your words. Keep it short and simple, you don't need to form a full sentence. Here you have some examples:
- Question: doing? Answer: Fine
- Question: color? Answer: Red
- Question: Name? Answer: Peter
- Now translate it to morse code. Here you have an example:
- Normal - Question: color? Answer: Red
- Morse code - Question: −°−°Π−−−Π°−°°Π−−−Π°−° Answer: °−°Π°Π−°°
- Finally, send it using A and B buttons on your micro:bit board
Now that you know how to communicate via radio, you can send some messages with morse code!
IMPORTANT! If you're working in pairs, each pair has to have a different "radio group". For example radio group 1 for pair one, radio group 2 for pair two... Both components of the group need same radio group id but different to other pairs.
And finally, as I know you liked the dodge ball game from last activity very much, here you have another game, the snake game!! You just have to download it and send it to your micro:bit board.
Press B to turn right and A to turn left. Try to catch as many apples (dots) as you can without crashing!
