Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to BD139. BD139 is a Bipolar NPN transistor, it is mounted in the SOT-32 plastic package. It is designed for audio amplifier and driver utilizing complementary circuits. BD139 has a gain value of 40 to 160, which determine the amplification capacity of a transistor. It has three main pinouts which are a collector, base and emitter. It is used to control (On/Off) bigger loads that consume less than 1.5A.
BD139 is used in different industrial projects such as RF amplifier and Switching Circuits. In today's post, we will have a look at its pinout, Arduino interfacing, applications, Specifications, etc. I will also share some links whe ...
Update: We have created a new version of this library, which you can check here: Arduino Mega 2560 Library for Proteus V2.0.
Hello friends, hope you all are fine. In today's post, I am going to share Arduino Mega 2560 Library for Proteus. In the previous post, I have shared the Arduino UNO Library for Proteus and I have mentioned that I am gonna share more Arduino Libraries soon. Actually these days I am quite excited about this Proteus component designing and I am designing the Arduino boards as a starter. So, till now I have designed two Arduino boards in Proteus. First one was Arduino UNO which I have provided for download in previous post and today, I am going to share Arduino Mega 2560 Library for Proteus.
In the coming posts, I am gonna sh ...
In today's post, I am gonna share how to use LDR sensor in Proteus. Proteus, as we all know, is a very handy software and is used for circuit and PCB designing. It is also used for circuit and programming testing. It is normally used by engineers in their projects and contains a vast list of built-in components. I have posted a lot of tutorials on Proteus and I have got quite a positive feedback from the reader about these tutorials. So, I thought to share another component in Proteus which is quite hidden and I haven't seen much posts on it available online.
So, in today's post, first I am gonna explain what is LDR sensor? and we will see where it is used and how it is used. After that I will design a simple circuit in Proteus in which I will tur ...
Hello friends, I hope you are all fine and will be doing something special in your life. In today's post, we are gonna have a look at a detailed Introduction to MPU6050. MPU6050 is a sensor for motion processing devices. It is the world's first six-dimension motion tracking device. It was designed for low-cost and high-performance smartphones, tablets and wearable sensors. It is capable of processing nine-axis algorithms, it captures motion in X, Y and Z axis at the same time.
MPU6050 is used in different industrial projects and electronic devices to control and detect the 3-D motion of different objects. In today's post, we will have a look at its working, pinout, protocol, it's interfacing with Arduino, features, applications, etc. I will also share some links of projects wh ...
Hey learners! Welcome to another exciting lecture in this series of signals and systems. We are learning about the transform in signals and systems, and in the previous lectures, we have seen a bulk of information about the Laplace transform. If you know the previous concepts of signal and system, then this lecture will be super easy for you to learn, but if your concepts are not clear, do not worry because we will revise all the basic information from scratch for our new readers. So, without wasting time, have a look at the topics of today.
What is z transform?
What is the region of convergence of z transform?
What are some of the important properties of the region of convergence?
How to solve the z transform?
What is an example of the z transform in MATLAB?
What are the methods fo ...
Hello friends, hope you all are having fun in your life.
Today's tutorial is about the component designing in Proteus ISIS. This tutorial actually deals with the presentation of your project. Usually when students give presentation of their projects, then it is asked that add the circuit diagram of their project. Now when students open Proteus in order to design their circuit, they found out that the components they have used in their project are not available in the Proteus Directory. Now what to do ?
In that case, there's a need to design your own component in Proteus and place it in the circuit. Although, this new designed component won't work as the real co ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to MPR121. MPR121 is a touch sensor controller, its working is like the capacitor's working principle. This module has twelve electrodes points, it communicates via I2C protocol. When any objects come closer to an electrode point, we can observe the presence of an object by variation in capacitance of an electrode. It's working voltage should be between 2.5 to 3.6 VDC.
MPR121 is used in different industrial projects and electronic devices such as mobile phone and remote control systems. In today's post, we will have a look at its working, pinout, protocol, applications, etc. I will also share some links where I have interfaced it with other microcontrollers. If you have ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 1N4007. It is a PN junction diode. Diodes can be made by combining two different types of semiconductor e.g. P and N. PN junction is a junction formed between P and N types of semiconductors. You guys should also have a look at Introduction to 1N4148.
1N 4007 belongs to the series of 1NXXXX devices. Its an American standard numbering system standard used for semiconductor devices. This standard has been adopted globally now. In 1N 4007 the first part 1N indicates single junction semiconductor. 1N indicates 1 junction whereas N indicates the semiconductor diode. 4007 is the specific number to indicate the particular ...
Hello readers, we hope you all are doing great. In this tutorial, we are going to demonstrate how to interface and control a servo motor using an ESP32 board. After that, we will demonstrate how to create a webserver to control the servo motor’s shaft position with the ESP32 board.
Servo Motors are among the most important actuators in robotics, with applications ranging from RC planes to automated door locks.
Hardware components required
A servo motor
ESP32 development board
Connecting wires
Breadboard
Servo Motor
There are several specific types of electric motor applications in which the motor must rotate only at a specific angle. For such applications, we need a special type of motor with such a special arrangement that causes the m ...
Hey Guys! Hope you are doing great and having fun. Today, I am going to unlock the details on the Introduction to Lm324n. It is a seven pin operational amplifier that comes in discrete and compact single package.
It is a high gain voltage amplifier, where output voltage signal is much higher than the input voltage signal. I'll try my best to cover as many aspects as possible related to this operational amplifier so you don't need to go any where and you find all information at one place. Let's get started.
