When we think about what an antenna is, what do we 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. What other items around your home use Bluetooth?

Maybe Bluetooth connects 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, if you combine what you learn from this episode with all of the other coding concepts the series has covered (sequences, loops, variables, conditional statements), you will see that you could potentially program so many new and cool projects. We hope you do! Good luck. 

Teacher/Parent Notes:

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