My name is Abdul Rehman and I love to do Reasearch in Embedded Systems, Artificial Intelligence, Computer Vision and Engineering related fields. With 10+ years of experience in Research and Development field in Embedded systems I touched lot of technologies including Web development, and Mobile Application development. Now with the help of Social Presence, I like to share my knowledge and to document everything I learned and still learning.
PubNub provides an easy to use interface for IoT enabled devices .PubNub and NodeMcu makes great pair to create IoT enbled embedded Devices. It is simple Publish and Subscribe based protocol. Where any device can subscribe to any channel with subscribe key and could receive all messages published to that channel. On the other hand […]
Character LCD is very common and basic accessory, required in most of Embedded system projects. In today’s post we are making LCD Driver library(Compact Version) for our daily life project usage. Most of the code is inspired and borrowed from Flex-LCD Driver Library. In this driver we will only specific features which are required in our […]
RPM meter is very common problem in Embedded system development. Most of the time we need to measure RPM and for this we need some kind of RPM or Tachometer. The most common approach that is used for making Tachometer or RPM Meter is to measure pulses for a specif duration and then multiply it […]
There are a lot of ways to add PDF Viewer to your applications. But we are going to present one old but the simplest way to render your desired PDF Files into your Android applications. You may use to display files from assets which we are going to do in today’s post. Or you may […]
In this post we are going to create a frequency meter using arduino. This frequency counter will count the number of cycles per second and will display the output on 16×2 LCD. We used proteous for simulation purpose and to quickly test our circuit. Full source code is provided at end of the post.
Natural Language Processing or NLP is rapidly growing Research Field. There is lot of potential in this field. This is all about processing the way how humans speaks and communicate with each other. Natural languages are as complex as humans are. Because we, as Human can understand each other’s point of view with many different […]
In this post we are going to discuss about rapidly growing Research field which is about Language processing. We list down useful tools and previously well known developed APIs and techniques to use for processing Natural languages. NLP Techniques This Quora post explains it in little more depth. But here are some of the famous techniques […]
Making Http Request in android is very common when it comes to create a Restful API Client Application. Because this is a network call so it is very common that this task is kind of blocking call. When the API becomes more complex like when it needs to authenticate via OAuth2.0 or something, then the […]
Iterating through collection of items are very common problem in any programming language. But when it comes to latest modern programming languages like Kotlin, this task became more fancy and more options become handy to do different type of iterations. Today we are going to take a deeper look into different version of for loops […]
Speech Recognition is always a difficult and interesting task to do for a lot of beginners. In this post, we are going to describe an easy way to do this tuff task using PocketSphinx. Also, there are more options available in the package other than CMU Sphinx (works offline).
