Hi Friends! I hope you’re well today. I welcome you on board. In this post, I’m going to discuss the Introduction to BC549. BC549 is a general purpose bipolar junction transistor that belongs to NPN transistor family. It contains three pins where small current change in one terminal produces a much large current change across other terminals. In other words, it is nothing but a current booster.
It is known as a low power low voltage current controlled device and is used for switching and amplification purpose. In this article I’ll be discussing complete details of BC549 transistor i.e. pinout, working principle, power ratings, physical dimensions and applications. Stay tuned.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I would like to provide a complete discussion on Introduction to C945. You will see a detailed description on the basics of the transistor C-945 and its different parameters. I have already shared Introduction to MMBD914, 74HC245, NE556, LM348 and PIC18F4550. So, must go through these tutorials in order to have better understanding about different IC's. C-945 transistor is basically a Negative Positive Negative (NPN) bipolar junction transistor.
C945 is usually used in the electronic circuits where there is a need of high speed transistor and a low current. C-945 has three semiconductor regions named as emitter, base and collector respectively. Since C-945 is a bipolar ...
Hey Everyone! I hope you are doing great. We always come with some awesome topics related to engineering so you can excel and progress in your relevant field. Today, I am going to give you a brief details on the Introduction to 2n1711. It is an NPN (Negative-positive-Negative) bipolar junction transistor (BJT) which is mainly used for amplification and switching purpose. It encompasses low leakage current, high break down voltage, and low capacity which makes it useful over widely current range. I'll try to touch every aspect related to this transistor so you can get an idea what it does and what are its main applications? Let's get started.

Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

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 ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on Flame Sensor Arduino Interfacing. Flame sensor is an electronic device which is capable of sensing/detection of fire or a high temperature zone. It gives an indication through an LED attached at its top, just after sensing the fire. These type of sensors are usually used for short ranges. They are able to detect the fire up to 3 feet. Flame sensors is the most common device available in the market these days due to its good results and cost efficiency. You should also have a look at Flame Sensor Library for Proteus.
Flame sensors are available in the market in two types one having three pins and the other having four pins ...
Hello friends, I hope you all are doing well. In today's tutorial, we are going to design a Home Security System using Arduino UNO in Proteus software. It's the most commonly designed engineering project, especially in electrical, electronics and mechatronics engineering. Normally engineering students design it as a semester project during their engineering course.
So, today we will design a home security system from scratch in Proteus software. I have given the complete project below to download but I would suggest you to design it on your own so that you could understand it better. So, let's get started:
Home Security System: Project Description
Before going into the detail, let's first download the complete Proteus Simulation with Ardui ...
Hello friends, I hope you are all fine and doing great. In today's tutorial, we will have a look at a detailed Introduction to MFRC522. MFRC522 is an RFID Embedded module used to read and write RFID cards and operates at 13.56MHz contactless communication. It is a less costly, low-voltage, and small-sized non-contact card chip. It is the best choice for intelligent instruments and portable handheld devices. It communicates with microcontrollers over SPI Protocol.
MFRC522 is used in different engineering projects, mostly for security purposes in offices, banks, plazas, etc. You must have seen in English Movies that a person just shows his ID card to the machine and its whole profile data pops up on the computer and if he is authorized then the front door automatically ...
Hello Everyone! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to Arduino Uno WiFi Rev 2.
Arduino Uno WiFi Rev 2 is a microcontroller board based on ATmega4809 and carries an ECC608 crypto chip to ensure a secure and safe WiFi connection. The board contains 14 digital I/O pins, 5 PWM pins, 6 analog pins, one SPI protocol, one I2C, and one UART communication protocol.
I suggest you read this entire post till the end as I’ll detail the complete Introduction to Arduino Uno WiFi Rev2 covering pinout, pin description, features, programming, and applications.
Let’s jump right in.
