Enjoy The Warmer Weather Safely With A Sunscreen Reminder Hat #AdafruitWeekendProject

Get help rememebering to reapply with this Sunscreen Reminder Hat tutorial using FLORA.

Help remember to reapply your sunblock by building a reminder right into your hat! This sewable circuit uses a FLORA sewable microcontroller and its compatible UV index sensor to sense the sun and play a tune on a piezo buzzer when its time to refresh your SPF.

This is a good beginner project because it doesn’t have very many parts and requires no soldering. For this project you will need:
• a hat on which to build your circuit
• FLORA main board (The UV sensor does not work with Gemma or Trinket, so a Flora is required!)
• FLORA UV index sensor
• piezo buzzer
• 500mAh lipoly battery
• 2-ply conductive thread
• sewing needle and plain thread
• scissors
• pliers
• clear nail polish
