Welcome in another Arduino tutorial. Today we are going to explain how to interface 4 digit 7 segment display using shift register 4094. We used CD4094 shift register for interfacing but the technique is same and you can choose any other shift register of your choice like 74HC595 etc as well. Also the code written

Today we are going to create a simple login page using PHP and MySQL. Login Systems are very first and basic needs when it comes to website development due to the large user-base. For any new developer it seems a trivial task to create a very basic but somehow secure login system. That is the

I recently find out that OpenCV have Deep Neural Network module which is purely CPU based and no GPU required. So I thought to give it a try. I searched online and come up with this Real time Object detection on Raspberry PI tutorial Which further remove my doubts on the DNN’s biggest nightmare of

In this tutorial we are going to learn the usage of findcontours and drawcontours functions in OpenCV Python. We will create code for doing this in real time using Webcam. This code will help you in further image processing and computer vision projects where finding contours or Objects be the first task before doing any

Color Segmentation is very basic problem in digital image processing. Most of the time we need to segment Object based on their colors. So Color segmentation comes in handy in such scenarios. Today, we are going to explain how to segment RGB Image based on some basic Primary Colors. This technique could also be applied

To achieve rgb to hsv conversion in matlab we can see that MATLAB Image processing toolbox provides functions for converting between different color spaces. Like to convert from RGB color space into HSV color space we have function called rgb2hsv() we need to pass RGB Image to this function and this function will return a

We are going to interface LCD 4 bit mode with stm8s103f3 microcontroller. The code will be equally applicable for similar line STM8 microcontroller. The language we are going to use is C and the compiler we used is COSMIC C compiler for STM8. The IDE that we used for writing our code is STVD from

Flask is a micro-framework in Python for developing web applications. Flask supports jinja2 template engine. We will use Flask framework for developing our mini (sometimes major) IoT based Applications in Raspberry PI. Because of it’s REST like request handling system it become very easy to develop APIs and/or web clients/server like applications. Flask is very

Today we are going to deal with Firebase Real-time database in Kotlin. If you did not already know how to add firebase to your android project you may follow instructions on official Firebase Setup Guide. But the easiest way is to add firebase with the help of Android Studio. You may choose any method that
