Check out this new guide from the Adafruit Learning center: Make a wedding bouquet and boutonniere set using Neopixels and a Feather 32u4 Radio. The brightness of the glow increases as the two get closer together, and dim when they move further apart.
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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
