DS18b20 is a temperature Sensor module which works on single wire protocol. The reason to choose DS18b20 as a temperature sensor is because, we can interface many DS18b20 sensors on single wire. So we do not need extra pins for interfacing as well as we also do not need analog pins. Because ESP8266 Nodemcu module

React bootstrap is a very handy and popular framework for using the bootstrap in React.js applications. Today we are going to create a react-bootstrap navbar example. In this example I will show you from a simplest navbar to a little bit complex one. So grab your keyboards and let’s get started. Installing react-bootstrap First thing

In this post we are going to read ADC1 channel 10 on GPIO PC0 on STM32F4 Discovery board. First of all we will set the Clock PLL to run the discovery board on full speed with 168Mhz frequency. Later we initialize the USART with the baudrate of 230400 Kbps and finally we initialize the ADC

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
