Show an icon or a message on the screen when two micro:bits are close together.
For this exercise try to make a 'hot and cold' game. One player hides their micro:bit somewhere in the room, and the other person has to hunt it using the graph on the other micro:bit. When they get closer they get 'hotter'. If they move in the wrong direction, they are 'getting colder'. Write the code so a victory message appears when the two micro:bits are very close together.
Think about how you would be able to tell when the player has found the other micro:bit.
You might want to use an if block in your code.
Test your solution on the simulator.
Download your code onto the micro:bit and test it.
