Send all the Messages!

Program both Micro:Bits to be both a sender and a receiver so you can communicate back and forth. Then switch power from the laptop to the battery pack and test out your wireless communication system! When the sender sends a message, the puppet will notify you to check the LED screen so that you can see the incoming message.

How far of a range can you get? Test it out!

There are tons of other extensions to this introductory project, here are some possibilities:

- Add more message options by adding more inputs or changing how those inputs are read; 

- Instead of a table-top alert system, build a wearable alert system;

- Send voice messages and/or other sounds.

Happy building!
