iWatch Heart Rate Monitor with Twitter Fabric, EON, Raspberry Pi @Raspberry_Pi #piday #raspberrypi
Great project + write-up from Lizzie Siegle up on PubNub.
Since last July when I first developed for the Apple Watch, I have watched this wearable struggle to rise in popularity. Although it is just an extension of the iPhone, on which it relies heavily, some of its features are fun for both users and developers. HealthKit gives developers access to fitness data, like heart rate and number of steps. While your step count can be a good measure of fitness, it is a measurement best analyzed at at the end of the day because that number takes time to grow. On the other hand, heart rate is more of a realtime statistic.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
