Hello friends, Hope you are doing good and having fun. I am here with another article on the blockchain. Previously, we have discussed the blockchain, some of its concepts, and its characteristics, and today I will talk about transactions. We would also explore the concept of gas in this tutorial. So let’s start by defining a transaction.
What is Ethereum Transaction?
A transaction is a message signed by an account owner that is added to a block and recorded in the blockchain.
A transaction is initiated by an externally owned account and then it gets transmitted to the Ethereum network.
It can be originated only by an externally owned account (an account owned by a human) and not by a contract account.
Through transactions, one can inter ...
Hey Guys! Hope you all are doing great and having fun. Today, I am going to discuss the details on the Introduction to Buck Converter. It is a power converter which is mainly used to stepping down the voltage from its input to the output load. It mainly consists of two semiconductors and one energy storing components which can be either capacitor or inductor. It works best in the circuits where electrical isolation is not required.
Introduction to Buck Converter
Buck converters are power converters which are mainly used for converting high voltage to the low voltage. These converters are highly efficient, showing almost 90% of efficiency.
They are useful for performing a special task like converting the huge supply voltage of 12 V in the co ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial looked at how to Interface DS18B20 with Raspberry Pi 4. This tutorial will teach us how to create a time-lapse video with still images and understand how phototimer and FFmpeg work.
What is time-lapse?
When photographing something over a lengthy period, "time-lapse" comes to mind. A video can be created by mixing the still photos. Plant development may be tracked with time-lapse movies, as can the changing of the seasons. They can also be utilized as low-resolution security cameras.

Cameras that can be used with the Raspberry Pi are a bit limi ...
Hi Fellas! Hope you are doing well. I am back to give you a daily dose of useful information. Today, I'll highlight and cover the Tips on working and completing college homework.
Students starting their college are asked to write a report and particular topics and technicality and involved in writing report and more complicated for students. Not exactly as unfortunately and lack to write a good report due to lack of effective writing tips and skills that is amazing is best.
Actually, homework assignment writing and which need so much concentration and depth knowledge and the information are better to complete the homework assignment. If are experiencing problems and homework and would be as prudent to allow homework support is best.
Tips on work ...
Hey there, I hope you are having a good day. Printed circuit boards (PCBs) are a popular topic in the electronic world and we also know that PCBs have revolutionized circuits. They not only provide a solid base but the material used in the PCBs helps the circuit to function properly by protecting the circuit from factors like external radiation. These are present in different materials that divide the working, stability, and reliability of the circuit. In recent years, there has been a significant change in the types and strength of PCBs and this depends on the materials used in the manufacturing of these boards. We are interested in studying the advanced materials used in the manufacturing of PCBs and knowing the right type of material for the right circuit.

If you’re in the market for new CAD software, may we suggest you focus on cloud-based options?
There are two reasons for this: one, cloud-based CAD solutions are more flexible, considering they operate on remote servers that you can access from just about anywhere; and two, most are subscription-based, so you’ll avoid exorbitant costs for the program and high-powered workstations. There are more benefits
, but we’ll save some for the rest of the blog post.
The question, though, is how to choose the best cloud-based CAD software for your projects? With so many options on the market - Onshape, AutoCAD Web App, Fusion 360, Autodesk, and more - picking the best one can seem like an impossible task.
The good news is, there is no single best CAD software; there is only the right one for yo ...
Hello friends, I hope you all are having fun. Today, we are going to share the 7th tutorial of Section-III in our Raspberry Pi Programming Course. In the last tutorial, we interfaced a DHT11 sensor with Raspberry Pi 4. Today, we are going to interface another temperature sensor i.e. DS18B20 with Raspberry Pi 4.
DS18B20 is a popular temperature sensor especially in severe/critical environments i.e. chemical plants, mines, industrial sites etc. because of its 1-wire operational technique and accurate readings up to 4 decimal digits.
Project Description
Today, we will interface a DS18B20 temperature sensor with Raspberry Pi 4 and will display the values on a 16x2 LCD.Let's have a look at the components required for this project:
Components ...
Hello friends! I hope you will be absolutely fine and having fun. Today, I am going to give you an elaboration about Introduction to 50N06. 50-N-06 is a device having three terminals named as gate, drain and source respectively. It is made up of silicon and is capable of current conduction up to 50A. I have already shared basic knowledge about different electronic devices in my previous articles like Introduction to MC34063, MMBD914, MSP430, NE555, NE556 and LM2902. Before going into the details of this article you must go through my previous tutorials for the better understanding.
50-N-06 provides fast switching speed. 50N06 is an N-channel power Metal Oxide Field Effect Transistor (MOSFET) specially designed to handle particular power levels. ...
Hi everyone! Thank you for viewing this article, I welcome you on board. In this post I’ll walk you through the detailed Introduction to BC546. BC546 is a low power NPN transistor mainly used for general purpose amplification and switching applications.
In this read you’ll study all nitty-gritty of BC546 transistor i.e. from pinout, pin configuration, and working principle to power ratings, key parameters, physical dimensions and applications. Keep reading.
Introduction to BC546
BC546 is a bipolar junction NPN transistor that finds applications in switching, amplification, impedance, H-bridge and current mirror circuits.
This transistor falls in silicon epitaxial planar transistor category which is generally divided into three groups A, B &am ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Interface Arduino with 74HC595 & 74HC165. I have already interfaced these shift registers separately with Arduino. In the first tutorial we have seen Arduino 74HC595 Interfacing in which I have discussed How to increase the output pins of Arduino using 74HC595. After that in second tutorial we have seen Arduino 74HC165 Interfacing where we have increased the input pins of Arduino.
So, now we are gonna interface both of these shift registers with Arduino UNO and will increase both input and output pins of Arduino. I have also given the Proteus simulations for download at the end of this tutorial along with Arduino code. So, lets get started with In ...
