Shift Register

Snake Game has been very popular since the beginning of the Mobile phones. Initially it was come in Black and white cell phones, and soon became very famous. Then with the advancement of the Cellphones, this game has also changed a lot, and now many graphical and colourful versions of this game are available.

Snake game has also become very popular…

Persistence of Viasion is a fundamental principle that allows our eyes to perceive continuous motion from separate images, a concept crucial to the illusion of motion in cinema. When I was a kid, I was always fascinated with it. So, in this project, we are going to use this fascinating optical phenomenon to create a cool-looking POV Display. You must have seen a lot…

Have you ever wanted to add some cool lighting effects to your electronic circuits or spice up your home decor with a mesmerizing light show? Well, a circular LED chaser might just be what you're looking for! And the good news is that it's easy to build one using the 74HC595 integrated circuit. So in this article, we will show you how to build a stunning circular LED…

All microcontrollers have specific numbers of IO pins but in some applications, like in a 7-Segment Display, we will need more GPIO pins than what our controller could offer. For such cases, where multiple output pins are required but the microcontroller has a limited number of output pins, 74HC595 Shift Register would be a perfect choice. 74HC595 is a shift register that…

Digital wall Clocks are getting more popular now days and they are better than analog clock as it provides accurate time in hours, minutes and seconds and its easy to read the values. Some digital clocks also have many facilities like displaying temperature, humidity, setting multiple alarms etc. Most of the digital clocks use seven segment display.

There are possibilities in embedded design where you do not have enough I/O pins available in your microcontroller. That can be due to any reason, may be your application needs multiple LEDs or you want to use multiple 7-segment displays, but you don’t have required I/O pins in your microcontroller. Here comes a perfect component, shift register. Shift register accepts…

In this tutorial we will see how to interface NodeMCU with 16x2 LCD without using I2C communication. Here we will interface 16x2 LCD using shift register SN74HC595. We can also interface it even without using any shift register. We will see both kinds of interfacings in this tutorial. Main difference between both interfacings is the number of pins used in NodeMCU.

Shift Registers are sequential logic circuits, capable of storage and transfer of data. They are made up of Flip Flops which are connected in such a way that the output of one flip flop could serve as the input of the other flip-flop, depending on the type of shift registers being created.

Raspberry Pi is an ARM architecture processor based board designed for electronic engineers and hobbyists. The PI is one of most trusted project development platforms out there now. With higher processor speed and 1 GB RAM, the PI can be used for many high profile projects like Image processing and Internet of Things.

For doing any of high…

In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output. Although there are more pins on ATMEGA328P controller than on UNO, this is because while designing the board some pins are defaulted.

Now for some applications we need more than 30 pins, say if we want to…
