Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give an Introduction to 2N3904. It is basically an NPN transistor made up of silicon material. It acts as a general purpose amplifier and switch. You should also have a look at Introduction to 2N2222 , which is also an NPN transistor and considered as 2N3904 equivalent. It is mostly used for lower power amplifiers and switching applications. Its major functional area is enclosed in TO-92 package. Its a silicon NPN general purpose bipolar junction (BJT) transistor designed for switching purpose as well as for an amplifier. Its can bear lower amount of current, lower power and medium voltage levels. It is most commonly used BJT due to its smaller size, wide availability and low cost. It is less sensitive ...
Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you an Introduction to 2N2222. It is the most commonly used Negative-Positive-Negative (NPN) Bipolar Junction Transistor (BJT) available in the market now a days. 2N2222 can be used for different purposes e.g. switching and amplification of analog signals. I hope you have enjoyed the previous post on Introduction to ULN2003 . The major functional area of 2N2222 is enclosed in TO-18 package. Due to the low cost and small size it is the most commonly used transistor. One of its key features is its ability to handle the high values of currents as compared to the other similar small transistors. Normally it is capable of switching a load current of 800mA which is really high rating as compared to other ...
Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation . If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons. Libraries ULN2003 Simulation Libraries Latest library: 28BYJ-48 Stepper Motor and ULN2003 Driver Library for Proteus V1.0 (October 2026) Other motor drivers: L298 · L9110S · TB6612FNG · BTS7960 · A4988 / DRV8825 · PCA9685 Servo · Relay Module Helping Tools Serial Monitor Advance : a serial terminal window for the UART of ...
Hello everyone! I hope you all will be fine and having fun. Today, I am going to share my knowledge about How to use MATLAB input Function. In this tutorial I would like to tell you about the importance of getting data from the user in MATLAB. If you want to display the data to users, you need to get data from them as well according their requirements. I hope you have read How to use MATLAB ? In this way the same source code written in MATLAB will give different result according to the requirements of the each user. So, in other words the source code becomes generic in this way. As we run the program, command window of the MATLAB asks user to enter the desired input. The results on this window are generated according to the Matlab input given by the user. You should also have a look at Lap ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about How to use MATLAB. This is an on demand tutorial. The tutorial will help you to learn the the basics of the MATLAB and will elaborate the use of the different tools of it e.g. command window, m.file, Graphical User Interface (GUI) and simulink. Before into the details of this tutorial you must go through Introduction to MATLAB first for the better understanding of this tutorial. Each of the tools has its own importance while making an algorithm in MATLAB. Command window basically deals with the shorter commands where there is a need of quick execution. Command window shows the result of all of the executed commands if there is no semicolon at the end of the particular statem ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share a list of Stepper Motor Projects using different software e.g. Arduino, Matlab and NI LabVIEW. I have already shared these projects but they are posted randomly. So, today I thought that I should combine all those projects into a single one. So I am going to share the links of all of those tutorials in this tutorial so that it may be helpful for engineering students or anyone who wants to visit. This tutorial will help you to visit all of my Stepper Motor Projects. You should also have a look at this Stepper Motor Simulation in Proteus. The links of all the tutorials will be given and you will be able to download the desired project code or simulation from the corresponding link. I will make s ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share a list of tutorials on DC Motor Projects using different software e.g. Arduino, Matlab and NI LabVIEW. I have already shared these tutorials but they are posted randomly. So, today I thought that I should combine all those tutorials into a single one. So I am going to share the links of all of those tutorials in this tutorial so that it may be helpful for engineering students or anyone who wants to visit. This tutorial will help you to visit all of my tutorials related to DC motor control. The links of all the tutorials will be given and you will be able to download the desired tutorial from the corresponding link. I will make separate sections for each software to control DC motor. In each se ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to tell you about how to design an algorithm for Servo Motor Control using Arduino . First of all I would like to tell you a bit about the servo motors. Servo motors are small devices having an output shaft. We can adjust this shaft in different angular positions by continuously sending the servo coded signal. Servo motor maintains the angular position of the shaft as long as the coded signal is present at the input. If the applied coded signal changes, angular position of the shaft of a servo motor also changes correspondingly. If you are working on Servo Motor then i would suggest you to must have look at this tutorial Servo Motor control in Proteus , as its always a best practice to design simulatio ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of you about how to make a simple program for DC Motor Direction Control in LabVIEW. In my previous tutorials, I have also worked on DC Motor Direction Control using Arduino . You should go through these tutorials they will be helpful in better understanding of the tutorial DC Motor Direction control using NI LabVIEW. The word DC is basically an abbreviation of Direct current . So, a direct current motor is commonly used motor having two input terminals, one is positive and the other one is negative. If we connect these terminals with the voltage supply the motor will rotate. If you change the polarity then motor will rotate in opposite direction. You should also have a lo ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of you guys, about how to make a simple Virtual Instrument (VI) for DC Motor Speed Control in LabVIEW. In my previous tutorials, I have worked on DC Motor Speed Control using Arduino , in which I have controlled the DC Motor Speed using Arduino and after that I made some advancements in it and then created DC Motor Speed Control in Matlab in which commands were sent from Matlab. So, now we are gonna do the DC Motor Speed Control in LabVIEW.If you are working on DC Motor then you should also have a look at DC Motor Direction Control using Arduino . In this tutorial, I am going to work on the program for DC Motor speed Control using NI LabVIEW. So, before going into the det ...
