Building an Apple iBeacon with CircuitPython #CircuitPythonDay #CircuitPython #Bluetooth
iBeacons are Bluetooth Low Energy (BLE) devices used in location awareness applications such as welcoming people as they arrive at an event or broadcasting information to compatible devices at a nearby museum exhibit. The term iBeacon is Apple’s implementation of the technology and reportedly, is what they use at their stores to send notifications to iPhone users as they enter/leave the store.
iBeacons can be bought online, but the purpose of this short post is to reuse a BLE capable small microcontroller running CircuitPython as an iBeacon. In my case I’ll be using Particle Xenon device, but this Adafruit Microcontroller would work just fine (or this one).
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.
