Here is the code to multiplex 4 digit 7 segment on Atmega8 using Timer 2 Interrupt. This code witll display digits array on seven segments. In our case we used 3024 to display on 7 segments.

Led blinking example is considered a hello world program for any Hardware based softwares. So today we are going to blink the LED in my Nexys 3 Board. This example will serve the both examples, VHDL as well as Verilog. First of all we will look for the VHDL example. VHDL LED blinking Code Here

Using STM32 ADC with Timer Trigger option it helps us to control the sampling time of the ADC. It also becomes important when we need to sample Audio or while making some waveform analysis options. In this tutorial we are going to extend our previous STM32 ADC+USART example, where we implemented the ADC basic single

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

If you had done Android development before, you may be very well aware of the concept of the Activities and switching between activitis. Or passing data using bundles between activities. But when it comes to the Flutter we don’t talk about the activities anymore. Because of the more web friendly development, Flutter also call its

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
