Making an iOS App for Adafruit Feather NRF52832 #Bluetooth #Programming

The Adafruit Feather nRF52832 has a BLE (Bluetooth Low Energy) functionality which has potential to be used in many different projects. In an Instructable, akiofujita steps through a project creating an iOS application that receives data sent from a Feather and graphs it.

The app is essentially updates a chart, in real-time, with data read from an Adafruit nRF52832 Feather board. The guide walks you through all the basics of creating a user interface (UI) using Apple’s Storyboard interface, a simple drag-and-drop scheme similar to something you’ve probably used in many other contexts.

They show readers how to add buttons for allowing users to interact with the app, labels for displaying data to the user, as well as walks you through Apple’s odd methodology of connecting UI elements to code using IBAction and IBOutlets. The highlight of the tutorial is showing readers how to add charts to their iOS apps which seems to take a few more steps than you might imagine.

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.
