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.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
