With this scarf, you’ll never have to wonder how cold it is when you step outside.
Winter is well underway in some parts of the country, and if you have to head out into the frigid air, you’ll probably want a comfy scarf around your neck. But what about an accessory that not only keeps you warm, but looks and functions as a giant thermometer as well? That’s exactly what Instructables user “caitlinsdad” has created using an Adafruit FLORA (ATmega32U4), humidity and temperature sensor modules to detect the weather conditions, a NeoPixel ring for the bulb, and an LED strip to reveal the temp in both Fahrenheit and Celsius.
