Lorraine Underwood is presenting at this weekend’s Raspberry Pi Fields event and built a wearable necklace using an Adafruit HUZZAH ESP8266, a NeoPixel ring, and a LiPo battery pack.
The necklace integrates Adafruit IO with IFTTT to let the crowd change the heart’s colors during her talk.
Necklace is working. I’ll wear it on stage. If you tweet me it will go blue! Snapchat – yellow. Email – red. Text – rainbow!!
Good luck at the event, Lorraine!
