If you’re doing any Bluetooth LE development on Android around our Bluefruit LE family of devices, you’ll be happy to hear that the source code for our Bluefruit LE Connect app for Android is now available in a public repo on Github. This should be a good reference if you’re working on custom apps since it address some of the edge cases around the Android BLE stack, and should point you in the right direction to implementing your own UIs, or extending Bluefruit LE Connect for your own purposes.
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.
