An IoT Triad Demo, Part I – Device (nRF8001 + Arduino) #Arduino #IoT
Thanks to Mahesh for sending in his project! Check out more on his blog here.
Internet Of Things (IoT) implementations usually consist of three parts – the device itself, software that interacts with the device (which usually runs on a mobile platform), and a cloud part that can serve as an intermediary, which may host web apps for controlling the device or dashboards for device data. In this three-part article, I demonstrate an “IoT triad” by developing a simple Bluetooth Low Energy (BLE) device, a cross platform mobile application, and data visualization on the cloud. In this first installment of the project, I will focus on the device part.
Bluefruit LE – Bluetooth Low Energy (BLE 4.0) – nRF8001 Breakout – v1.0: Our Adafruit Bluefruit LE (Bluetooth Smart, Bluetooth Low Energy, Bluetooth 4.0) nRF8001 Breakout allows you to establish an easy to use wireless link between your Arduino and any compatible iOS or Android (4.3+) device. It works by simulating a UART device beneath the surface, sending ASCII data back and forth between the devices, letting you decide what data to send and what to do with it on either end of the connection.

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.
