Change the messages being sent, by using the buttons

Learn how to edit the message

If you haven't done it yet, use these instructions and set up the new code.

Change the message when you press A

The message that should be sent is stored in a variable, by naming it message. We can change the value of message, and the micro:bit will use the most up to date value.

• From the Inputs menu, choose the on button A pressed event.
• From the Variables menu, choose set message to 0, and put it inside the on button A pressed event.
• From the Advanced menu, go to the Text menu, and find the (" ") block. Put it onto the set message to block, replacing the 0.
• You can now add whatever you want into this space.

When the program starts, your receiving micro:bit should see the original message.

If you press button A, the receiving micro:bit should see the button A message instead.

Once your code works, see if you can expand it to also use button B.
