Hey Friends! Hope you are doing well. Today, I am going to give you a detailed Introduction to Arduino Pro Mini. It's a microcontroller board developed by Arduino.cc and is based on the Atmega328 microcontroller.
Arduino Pro Mini is quite similar to Arduino UNO in overall functionality however the main difference lies in its size and built-in programmer. Arduino Pro Mini is very small in size & it lacks a built-in programmer & USB Port. Arduino Uno comes with two onboard voltage regulators (i.e. 5V and 3.3V) while Arduino Pro Mini comes with a single voltage regulator.
There are two versions of Arduino Pro Mini available, first one operates at 5V & runs at 16MHz while the second one is of 3.3V runs at 8MHz.
Arduino boards are mainly u ...
Hi Friends! Hope you are doing great. Today, I am going to give you a detailed Introduction to Arduino Uno. It is a microcontroller board developed by Arduino.cc and is based on Atmega328 Microcontroller. The first Arduino project was started in Interaction Design Institute Ivrea in 2003 by David Cuartielles and Massimo Banzi with the intention of providing a cheap and flexible way for students and professionals to learn embedded programming.
Arduino UNO is a very valuable addition in electronics that consists of a USB interface, 14 digital I/O pins(of which 6 Pins are used for PWM), 6 analog pins and an Atmega328 microcontroller. It also supports 3 communication protocols named Serial, I2C and SPI protocol. You should also have a look at this vid ...
Hey Fellas! Hope you are doing fine. Microcontrollers play an important role in the development of embedded systems. They are used where automation is an integral part of the system. Today, I am going to unlock the details on the Introduction to Atmega16.
It is a 40-pin low power 8-bit microcontroller which is developed using CMOS technology and based on AVR architecture. This is the most commonly used AVR microcontroller which belongs to Atmel Mega family.
You must have a look at microcontroller called Atmega328 that also belongs to the mega family.
Other microcontrollers that are readily available and fall under AVR category are Atmega 8 and Atmega 32. All these controllers perform similar tasks, however, they are only different in terms of ...
Hello Friends! Hope you are doing great. I am back to give you a daily dose of valuable information so you can excel and grow in your relevant field and keep coming back for what we have to offer. Today, I am going to unlock the details on the Introduction to 8051 Microcontroller. This is an 8-bit Microcontroller developed by Intel in the 1980s. It is considered as a small system on an integrated chip that comes with CPU, I/O ports, timers, counters, RAM and ROM. The Microcontroller is a one step forward to a microprocessor.
Both Microcontrollers and microprocessor work in a similar way with some exceptions. Microcottler comes with everything required to run an embedded system like CPU, I/O ports and inbuilt peripherals like timers, counters, ...
Hello everyone, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to design a Smoke Detector with Arduino. Its quite a simple project but if you are working on any security project then you must add this feature in it. You should also download this Gas Sensor Library for Proteus, and design its simulation.
I will use gas sensor MQ2 for this project. I have purchased MQ2 Gas Sensor module as its quite easy to interface with Arduino. Arduino board I'm using is Arduino UNO. I have also designed an LPG Gas Leak Detect using Arduino using this MQ2 Sensor. So, let's get started with How to design Smoke Detector with Arduino & MQ2 Sensor.
Smoke Detector with Arduino & MQ2 Sensor
First of all, we need to conn ...
Hi Guys! Hope you are doing fine. Today, I am going to give you a detailed Introduction to Transistor. A transistor is a semiconductor device that comes with three terminals, where a small current at one terminal is used to control current at the other terminals. Transistors are mainly used for the amplification of electronic signals. Transistors were first invented by American Physicists John Bardeen in 1947.
Before the inception of transistors, vacuum tubes were used to control the electronic signals. These vacuum tubes come with anode & cathode arrangement and the potential difference across these ends produces the electric current. In the later versions, a filament is added which is used to provide heat to the cathode that directs the electrons towards the anode side. Their complex ...
Hey Guys! I hope you all are doing great. In the previous tutorial, we studied the basics of Semiconductors, where we briefly discussed the PN Junction. Today, we are going to have a detailed overview of PN Junction.
But before getting into the details of PN Junction, we need to first recall a few concepts from the previous lecture:
Semiconductor Basics
As we know, the conductive power of a semiconductor material lies between a conductor and an insulator. So, it can act as a pure conductor as well as a pure insulator, depending on the applied conditions. Semiconductors are divided into two types:
Intrinsic Semiconductor.
Extrinsic Semiconductor.
Intrinsic Semiconductor
A semiconductor in its pure form is called an Intrinsic semiconductor. In this state, the outermost valan ...
Hi Friends! Hope you are doing great. I am back to give you a daily dose of valuable information so you can excel and grow in your relevant field. Transistors are the fundamental parts of most of the electronic circuits. Today, I am going to unlock the details on the Introduction to 2n3903. It is an NPN transistor main used for general purpose amplification and switching applications.
Transistor comes in two types i.e. NPN and PNP transistors. This transistor falls under the category of NPN transistor. This is a bipolar junctions transistor where conduction is carried out by movement of both charge carriers i.e. electrons and holes. However, electrons are major charge carriers in case of NPN transistors. If you are unsure how these bipolar transi ...
Hey Friends! Hope you are doing great. I am back to give you a daily dose of valuable information so you can always stay ahead of your competitors. I have previously updated the article on NPN transistor that is used for amplification and switching purpose. Today, I am going to unveil the details on the Introduction to PNP Transistor which falls under the category of bipolar junction transistors and comes with three layers i.e. two P-doped layers and one N-doped layer where an N-doped layer exists between two P-doped layers.
Main Function: Small current at one terminal is used to control large current at other terminals.
Major Charge Carriers: Holes
These NPN and PNP transistors come with their own benefits based on the nature of the e ...

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.
