Build an iOS app that connects to IoT device using Bluetooth

Internet of Things (IoT) is one of the hottest technologies across the globe nowadays. There are a number of IoT products and devices that are available in the market.

At the end of this blog, you will have a high-level idea of how IoT systems work. To understand, we will create an iOS demo app which will send/receive data from an IoT compatible device with the help of Arduino.

We will cover the following points:

  • Introduction to IoT
  • Arduino Overview
  • iOS demo App to understand the end-to-end flow

iOS Build Management using Custom Build Scheme

Introduction

One of the best practices in iOS development is to be able to manage multiple environments during development of a project. Many a time we might have to jump between DEV, QA, STAGE, and Production environments. As the owner of a product, clients request to have both development version of the app and production version of the app i.e. App store released version of the app on the same device.

If you have ever faced or might face this situation, then you need a custom build scheme. Continue reading

Object detection with Turi Create and augmentation using ARKit

Introduction

Over the past few years, the use of Machine Learning to solve complex problems has been increasing. Machine learning (ML) is a field of computer science that gives computer systems the ability to “learn” (i.e. progressively improve performance on a specific task) with data, without being explicitly programmed.

Last year was a good year for the freedom of information, as titans of the industry Google, Microsoft, Facebook, Amazon, Apple and even Baidu open-sourced their ML frameworks. In this blog, let’s explore a framework provided by Apple named Turi Create. Continue reading

OCR implementation in Android

What is OCR?

Optical character recognition, Optical character reader or OCR is the process of reading printed or handwritten text and converting them into machine-encoded text. OCR is mainly used in the field of artificial intelligence, pattern recognition, and computer vision.

So how does it work? In simple words, for a computer, an image is nothing but a collection of pixels. In OCR processing, the image is scanned for light and dark areas to identify each character.  Continue reading

Proxy Routing in Angular 4 Applications

This blog intends to deal and simplify routing in Angular 4 applications in both development and production environment. While working on routing in Angular 4 applications, we often face some of the following challenges:

  • Finding a solution to the problem of cross-origin issues in Angular development environment
  • Separating routing configurations and APIs servers URLs from the code, making the application more robust and maintainable
  • Finding a generic solution where frequent changing of API URLs (due to deployment on different servers, let’s say for the purpose of load balancing) do not force you to modify and change the code
  • Servers where the APIs deployed do not appear in your code at all
