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.
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).
In today’s post, we are going to explain how to handle Jason Strings in Python. There is JSON module in python which is used for JSON string handling. Jason is very common in RESTfull APIs. JSON is the abbreviation of JavaScript Object Notation. Here is Tutorial about Python Dictionaries. We use Dictionary data structure for handling […]
Adafruit has a very good explanation about GPS interfacing. You may follow that tutorial or continue here. To view, the available USB to TTL converter devices use the following command ls /dev/ttyUSB* If you had installed pyserial then you may list all your available COM ports using this command via python python -m serial.tools.list_ports
We had mentioned using Raspberry PI GPIO as output in our previous post. Today we will talk about using Raspberry PI GPIO as input. We will try to read input from pushbuttons. We had connected pushbuttons as the Active Low state. Mean the pushbutton will remain in the Active High state unless we press any […]
After successfully installing raspbian into Raspberry PI, the first thing which comes into the mind of the embedded developer is to play with Raspberry PI GPIO. Because the very best advantage of this cheap computer is to use with external hardware through its GPIO. We are going to explain how to play with Rasberry PI GPIO’s […]
Timer0 of pic16f is popular and very basic for creating short delays or… for creating small timing pulses. It is an 8bit timer with high priority interrupt. Which makes it perfect for creating time-critical applications like frequency counter, some industrial timing control system or any medical or industrial grade application.
Accuracy is very important in Real-time applications. Especially with time-critical applications. so whenever we need something time critical we always need accurate timings. In such cases, we cannot rely on nop instructions based delays. We need something more powerful and more accurate. To handle this kind of errors we always use hardware-based timers. luckily Microchip pic […]
Abstract Food identification could be done in many ways as Every food is different in many ways, like shape, color, size and taste as well as many other chemical and electrical properties. What if we build some cool project out of it? Electronics is a fun to play with. So we are going to make […]
Introduction: The “OOK modulation” or On Off Keying Modulation is very popular now days due to VLC or Visible Light Communication. OOK modulation is easy to use and easy to implement. As we can even implement this modulation using simple 555 timer IC. In this post we are going to explain How to implement OOK […]
