Interested in integrating Bluetooth Low Energy into your next Arduino project with even more flexibility than our nRF8001 offered? You’ll love the new nRF51822 based Bluefruit LE UART Friend, based on a powerful ARM Cortex M0 System on Chip!
We updated the Bluefruit LE UART Friend learning guide to show you how to use all of the demo sketches in our library, including Controller mode allowing you to push sensor data from your phone out to the Arduino, the Heart Rate Monitor demo showing you how to dynamically create and update your own GATT Services and Characteristics, as well as documenting all the AT commands available on the module.
Doing something interesting with the new Bluefruit LE UART Friend? Make sure to let us know or share it with the world on our weekly show and tell!
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.
