This Mother’s Day make your Mom a gift from the heart with this Adafruit tutorial for a super chic heart shaped broach that shows the beat of her heart!
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.
