Check out the very first beta release of the Adafruit Bluefruit LE desktop application. This is an application that lets you interact with Bluefruit LE and other Bluetooth low energy devices right from your Mac OSX, Windows, and Linux desktop. Just like the iOS and Android app you can do things like:
View BLE device information like services, characteristics, and read characteristic values. Great for checking the firmware version of a device using its device information service.
Send and receive data with a BLE UART, like controlling an Arduino project over BLE.
Send control pad and color picker values to a BLE device over its UART connection.
Visualize a BNO-055 absolute orientation sensor using a 3D model.
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.
