A new guide in the Adafruit Learning System — Circuit Playground Bluefruit BLE Heart Rate Pendant with CircuitPython
Are you going to a dance party soon? Or maybe a speed dating night? Would you like to wear your heart out?
In this project, you can visibly show off your heart rate in the form of a pulsing pendant. A Circuit Playground Bluefruit (CPB) connects to a heart rate monitor to display the heartbeat of the wearer. Using the CircuitPython programming language, the CPB blinks with red NeoPixels to display the heart rate.
