Proximity Beacon

For this project, you will need 2 Micro:Bits. Start with the Proximity beacon project, and after you get it working expand the project by:

• Make the bar graph display on both Micro:Bits
• Make the display show a face that gets happier as the Micro:Bits get closer, and sadder as it gets farther away.
• Use these programs to make a treasure hunt game: hide the beacon and put the receiver code on lots of Micro:Bits
• If you’re outdoors or in a large space, experiment by changing the transmitter power. It can be any number from 0 to 7
