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
• clear nail polish
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
