When you think about the word 'antenna', what do you think of?

Some people think of insects. Some people think of metal structures sticking out at the back of the old television sets. Or some people think of a metal rod attached to their radio.

Well, the micro:bit has an antenna as well. Similarly to televisions, or radios, the micro:bit is able to send and receive signals with this antenna. What is interesting is that the micro:bit communicates through Bluetooth to do this. You can probably think of lots of ways you already use Bluetooth enabled devices. Maybe it allows you to connect a phone to the sound system in your home.

So, if you play music from your phone, you hear it from the speaker. However, when you first buy that speaker, there are more steps involved to make sure those two things are communicating together.

Challenge: Think about the steps you would normally have to take to connect two Bluetooth devices together so that they can communicate. 

This ability for the micro:bit to send and receive information (or data) over a Bluetooth connection can be very useful for lots of practical projects that we could create using the micro:bit. In particular for this series, understanding how to include radio in your computer program may be a very useful addition as you continue to work towards a possible project entry for the do your:bit project competition. 

Check out the resources including extra challenges for students and teacher/mentor guidelines for this episode HERE.

Teacher/Mentor/Parent Notes
The coding challenges will require students to have access to an internet connected device (phone, tablet device or laptop) and to log in, on the browser of choice, to makecode.microbit.org.

Don't forget, you can find all resources including series guidelines and episodic resources HERE. Good luck!
