Hello Friends! I hope you are well. Today, I am going to give you a detailed Introduction to NPN transistor. In this tutorial, we'll look at the NPN transistor, how it works, circuit diagram, output characteristics curve, and applications. It is a bipolar junction transistor mainly used for current amplification and switching purposes.
BJTs (Bipolar Junction Transistor) are divided into two types i.e. NPN transistor and PNP transistor. Both transistors are different in terms of their electrical composition and construction, however, both are used for amplification and switching purposes in one way or the other.
What is NPN Transistor?
NPN transistor is a bipolar junction transistor(BJT), composed of 3 semiconductor layers in a way that o ...

Hello readers, I hope you all are doing great. In this tutorial, we will learn how to access Firebase (a real-time database) to store and read values or data with ESP32.
It is Google’s mobile application development platform that can be used to can access, monitor and control ESP32 from anywhere in the world with its (firebase) real-time database.
What is Firebase?
Firebase real-time database is a development platform provided by Google which included multiple services to manage and authenticate data.
Firebase is basically a mobile and web app development platform I as works great with Android APIs) that includes features like firebase cloud, real-time data and Firebase authentication etc.
As per Firebase’s official documentation (https://firebase.google.com/docs/database), whenever a us ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to PC817. PC-817 is also known as an optocoupler / optoisolator. It consists of Infrared Emitting Diode (IRED). This IRED is coupled to a photo transistor optically and not electrically. It is closed in a four (4) pin package. This package is usually available in two different forms. The first one is wide lead (Pb) spacing option and the second one is SMT gullwing lead form option.
PC 817 has an internal LED and a photo transistor. The photo transistor's base becomes activate when LED throws light on it. The output obtained can be divided into two formats either common emitter or common collector. But the configuration is ...
Hi friends, today we are going to learn a good technique to run multi outputs in sequence. In another word, when we have some output that is repeatedly run in sequence. In the normal or conventional technique of programming we deal with them individually or one by one which takes more effort in programming and much space of memory. So instead we can use a new technique to trigger these outputs in sequence using one instruction which will save the effort of programming and space of memory. In this article, we are going to introduce how to implement sequencer output instruction. And practice some examples with the simulator as usual. Before starting the article, we need to mention that, some controllers like Allen Bradley have sequencer output instruction and some has not like Siemens. So we ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to LM339. LM339 belongs to the family of devices having 4 independent voltage comparators. Each comparator is designed in such a way that it is capable of operating from a single power source over a wide range of power supplies. It can also operate for split power supplies. There is a unique characteristic of comparators, Input Common-Mode Voltage Range (ICMR) includes a ground even when it is operating from a single power supply voltage.
Basically, LM339 is a comparator IC having four built-in comparators. The basic purpose of a comparator is to rotate the signal between analog and digital domains. At its input termina ...
Hi there! Hope this finds you well. I welcome you on board. Thanks for clicking this read. In this post today, I’ll be discussing the Introduction to D882 transistor.
D882 is a general-purpose transistor mainly famous for its high performance. It falls under the category of NPN transistor and is an ideal pick for commercial, educational, and hobbyists’ electronic projects. It comes in TO-126 with collector current 3A, projecting it can drive loads under 3A. There are three pins incorporated on the transistor which are used for external connections. The collector-emitter and collector-base voltages are 30V and 40V respectively with emitter-base voltage 5V, indicating only 5V are required to bias the component.

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to MCP23008. MCP23008 provides an 8-bit parallel input/output expansion for I2C bus and SPI applications. It has 8-bit configuration registers for input, output and polarity changing. The master device can enable input and output pins of MCP23008 by writing the Input/output configuration bits. A polarity of the input port register can be inverted with the polarity of the inversion register and all registers can be read by the system master.
MCP23008 is used in different industrial and class projects where I2C and SPI interfacing is required simultaneously. In today's post, we will have a look at its pinout, features, specifications ...
