She lights up the room when she walks in. Make sure everyone can see it.
Two Feather 32u4 Radio modules are hidden inside a bouquet and boutonniere along with a few discreet neopixels.
Using the radio signal strength measurements, the two Feathers can roughly determine how far apart they are. When the two get close together, the lights glow brighter, and when they separate the lights dim and flicker!
As she walks down the aisle, her bouquet will slowly increase in brightness until she’s standing right by his side, and beaming.
This technique will work great for any two costume pieces as well. Find your partner at the after-dark party by following the brightness of your light-up hat or other accessory.
