Build a badge to show the beat of your heart! This wearable project uses the Polar heart rate sensor, which you wear around your ribcage and it wirelessly transmits heart beats to the receiver chip included in our educational starter pack. The badge can be worn on your clothes or bag, and is held in place by a magnetic pin back. Make the heart-shaped NeoPixel version, or use one of our 8×8 LED matrices with i2c backpack to display your heart rate as a number or make your own bitmap animations. Watch the video on YouTube (please subscribe!) and Vimeo, and read the complete Heart Rate Badge guide on the Adafruit Learning System to build your own.
You will need the following items:
- Polar Wireless heart sensor educational starter pack
- FLORA main board
- 150 mAh lipoly battery (with charger)
- Eight FLORA NeoPixels or 8×8 LED matrix w i2c backpack
- Magnetic pin back
- Thin stranded wire
- Double-stick tape or foam
