NEW GUIDE: CircuitPython BLE Heart Rate Zone Trainer Display @adafruit @johnedgarpark #adafruit

NEW GUIDE ALERT: CircuitPython BLE Heart Rate Zone Trainer Display

Heart rate zone training can be an excellent way to monitor workout intensity and increase your fitness and endurance. For example, warm up at 50-60%, then enter the “fitness zone” of 60-70% for a period, then go into the “aerobic zone” of 70-80%, finally peak in the “intense anaerobic zone” of 80-90%.

Using a Bluetooth LE heart rate monitor armband or chest strap, you can send up-to-the moment heart rate data to a battery-powered Feather nRF5280 Bluefruit equipped with a pair of seven segment LED displays.

Place it on a wall or shelf where you can easily see it while you work out! Or carry it or hook it to your bike. CircuitPython makes it straightforward to connect to your heart rate monitor and stream the heart rate data and zone percentages to the displays.


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.
