This project is about creating a prototype of an affordable and highly wearable heart rate monitor. Ideally the form factor of the heart rate sensor would allow to wear it as a ring or wristwatch, which is convenient when practicing sports. In order to reach these objectives, the idea is to use an electronic module (the sensor) connected in Bluetooth Low Energy (BLE) to a smartphone (the user interface). This way the module will remain simple, small and could be used with any BLE heart-rate application.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
