Yesterday Google announced the release of Android 4.3, which includes a number of small updates. The biggest announcement (from an embedded point of view), though, is finally(!) adding an official Bluetooth 4.0 Low Energy stack and API into the main branch. BTLE (marketed lately as BT Smart) support in Android means that both iOS and Android can now speak a common language to any BT LE peripherals, along with the latest version of Windows Phone and Blackberry, which is a pretty compelling argument for engineers and product designers. There are some significant design tradeoffs using BT LE … it trades speed for a low energy footprint … but it should grow in important in the coming months and years as the mobile space takes over more and more of the tasks that were once limited to desktop environments.
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.
