Hi Friends! Happy to see you here. I welcome you on board. In this post, I’ll walk you through the Introduction to BC639. BC639 is a high current gain bipolar junction transistor that falls under the NPN transistor family. It constitutes a high collector current and low collector-emitter saturation voltage and is widely used for amplification and switching purposes. It is used to drive load under 500mA. Collector Dissipation is 0.625W while DC Current Gain (hfe) ranges from - 40 to 160 with transition frequency 200MHz. In this post, I’m going to discuss all nitty-gritty of the BC639 transistor covering pinout, working, power ratings, alternatives, applications, and physical dimensions.

Hello friends, hope you all are fine and having good health. Today, as the name suggests, I am gonna post on how to Receive SMS with AT Commands using Sim900 and Arduino. I have already posted a tutorial on How to Send SMS with Arduino UNO and Sim900, so now we are gonna check the opposite. Sending SMS is quite easy, you just need to write some AT commands and write the message you wanna send and hit the Cntrl + Z and it will be sent. But receiving a text message on your SIM900 shield is a bit difficult because now you need to place a check when user will send a message. So, ideally whenever anyone send a message to yo ...
Hello Learner! I hope you are doing great. Welcome to another tutorial at The Engineering Projects. This blog is the part of series we have stated about the Digital Logic Circuits. Previous to this, we learned Implementation of SK Flip Flops in Proteus. at the present day, we'll seek the knowledge about the following points:
What are Flip Flops?
What are JK Flip Flops?
How can we record the Truth Table of JK Flip Flops?
What is the Procedure to Construct the circuit of JK Flip Flop through Logic Gates and IC circuit?
Moreover, we'll also have some useful bits of Information in Did you know Sections. Let' see the explanation of the concepts given above.
Flip Flops
The Flip Flops are the building blocks of many of the Electronic Circuits. ...
Hi, friends I hope you are all well and doing the best in your fields. Today we will discuss the cross or the vector product. In the previous article, we discussed vector quantities, scalar quantities, and the scalar or dot product with their properties, and applications in different fields of science now we can talk about the cross or vector quantities in detail because vectors are used in mathematics, physics, engineering or many other fields. Algebraic operations can also be solved by using the vectors. Vectors are widely used because they can provide the magnitude and direction of a quantity.
The vector product is also known or termed as the cross product. Vector product or in the cross-product are binary vectors or these vectors are perpendicular to each other in the three-dimen ...
Small businesses rely on a specific set of technologies but optimizing the way they are used can be challenging. It is a task that requires ongoing assessment, and you will need to be able to evaluate the different options. Making these adjustments requires you to be proactive and look for potential issues before they come up. There are several ways you can optimize the tech you use.

Hey Fellas! Hope you are doing well. I feel pleasure to have you on this platform. Today, I'll discuss the detailed Introduction to Arduino Duemilanove which is a Microcontroller Board, introduced by Arduino.cc and is based on ATmega168 or ATmega328. It comes with 14 pins that can be used both ways: Input or Output. Duemilanove means "2009" in Italian.
Arduino boards have always been a good pick for hobbyists and students who intend to design projects that are mainly related to embedded system and automation. These boards are similar to microcontrollers, with little advantage over them as they come with some built-in peripheral features, setting you free from buying external components to employ automation in your project.
If we focus on Arduino ...
Choosing between 3D printing and CNC machining can be pivotal for manufacturers, designers, and engineers. Each method has distinct advantages, depending on factors like production volume, material requirements, and the complexity of the design. 3D printing offers unparalleled flexibility. It allows for rapid prototyping and intricate geometries that are difficult to achieve with traditional methods.
On the other hand, custom CNC machining
is known for its precision and ability to work with a wide range of materials, making it ideal for producing high-quality parts with tight tolerances. Understanding these differences is crucial for selecting the right technique for your project, whether looking to innovate quickly or produce durable, high-quality components.

You can use a multimeter to figure out what's wrong with the electrical system in your car. Most of the time, if you check for voltage and continuity, you can figure out where the problem is coming from. This article will show you how to use a multimeter on a car.
First, make sure the multimeter isn't on. Then connect the positive lead to the positive terminal on the battery. Connect the negative lead to a metal piece on the frame of the car. The last step is to turn on the multimeter and read the results. If it says 0 volts, it means that no electricity is moving through the circuit. If the voltage is 12 volts or more, then there is a current in the circuit.
A multimeter can be helpful if you can't figure out what's wrong with your car's electrics. You should be able to fix many c ...
Hello readers, I hope you all are doing great. In today's tutorial, I am going to share a detailed Introduction to Proteus. It's our first tutorial in Proteus series. Today's tutorial is for beginners but still I would suggest you to read it once, as I am going to explain why Proteus?
Throughout our Engineering Course, we have to design a lot of electronics or embedded circuits and it's always a best approach to simulate these circuits first on some simulation software i.e. Proteus, PSPice etc., before assembling them on actual hardware. Among these simulation software, Proteus is my favorite one so let's get started with detailed Introduction to Proteus:

Hello friends, I hope this article finds you happy, healthy, and content. Today, we are about to discuss one of the most commonly known types of transistors which you might have heard of many times when reading about transistors, the transistor under study is none other than the “Bipolar Junction Transistor’’, also known as BJT . In this article, we will go through the basics of the bipolar junction transistor including its meaning ,definition, types, characteristics, and applications. So, let's get started.
Definition of BJT
A BJT in its full form is written as bipolar junction transistor and we can define it as,
"A bipolar junction transistor is a three-terminal semiconductor device which is made up of two PN junctions within its structure a ...
