Hi Friends! Hope you’re well today. I welcome you on board. Today, I’ll walk you through the Introduction to INA219.The INA219 is a current sensor module that incorporates the I2C protocol for submitting the data obtained through sensing current, voltage, and power. It is a bi-directional zero drift current/ power sensing module mainly used in digital multimeters and power profilers.
I suggest you read this post all the way through as I’ll detail the complete Introduction to INA219 covering datasheet, pinout, features, and applications.
Let’s get started.
Introduction to INA219
INA219 is a current/power sensor module mainly employed to sense the power, voltage or current where up to 128 samples can be averaged together to get filtering in noisy environments. This data is then s ...
Hey Everyone! I hope you are doing great and having fun with your lives. I am back to give you a daily dose of information so you can grow and progress in your relevant field. Today, I am going to uncover the details on the Introduction to 2n4401. It is an NPN (negative-positive-negative) bipolar junction transistor (BJT) which is used for general purpose amplification and switching purpose. It consists of P doped semiconductor that exists between the two layers of N doped material.
I'll give you a brief detail about this transistor so you don't have to go anywhere for finding the information regarding this transistor. You can also check the Introduction to 2n4402 which is a complementary PNP transistor of this NPN transistor. Let's get started.

Hello friends, I hope you all are doing great. In today's tutorial, I am going to explain the Relay Interfacing with Microcontroller using ULN2003A. In the previous lecture, we have discussed the detailed Introduction to Relay along with its working. Now we are going to practically interface the relay with a microcontroller to design an automatic switch. Relay is a key component in almost every electronic circuit. It can be
used as a switch and can also be used as a voltage regulator.The microcontroller I am going to use here is PIC18F4552 but you can use any other Microcontroller. You just need to change the syntax of coding but the logic will remain the same. Here, I am using ULN2003A to control the relay and from this relay, we can control anything.So, let's get started:
Relay Inte ...
Hello readers, hope you all are doing great. Today, we will discuss interrupts and timers in ESP32 and how to handle internal as well as external interrupts. So, we will discuss What is interrupt, Polling, ESP32 interrupt, Software interrupts, Hardware Interrupts, IRS (Interrupt Service routine), Steps to execute an interrupt or how is an interrupt handled in the microcontroller, Code description for ESP32 interrupts with Arduino IDE, Code description for hardware interrupts, Why is it preferred to use timer to add delay instead of using delay() function. So, let's get started:
What is Interrupt?
Interrupts are used when a micro-controller needs to continuously monitor for an event while the same micro-controller is executing a particular task ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explain you about Introduction to LM386. Its a power amplifier specially designed for low voltage consuming applications. The gain of LM 386 is set around 20 internally. But the gain could be increased due to the insertion of external resistor and capacitor between the pin number 1 and 8. The gain could increase to any value from 20 to 200.
The LM-386 inputs are ground referenced. The output are biased to the half of the input voltage levels automatically. When LM 386 operates on 6V, its quiescent power drain is around 24mW. This property of LM-386 makes it ideal for the battery operation. Its major features include battery operation, minimum external p ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Introduction to STM32 Microcontroller. This microcontroller is a new category of a microcontroller family it is a thirty-two-bit microcontroller also compatible with the ARM and Cortex M processor. Due to thirty-two bits compatibility, this module provides good performance, processing of digital signal and consumes less power and voltage. The modules used in most of the industries due to their compatibility with the cortex M0, M0+, M3, M4.
In today's post, we will have a look at its working, features, pinouts, applications and some other related parameters. So lets with the Introduction to STM32 Microcontroller.

Hey guys! I aspire you a prosperous life filled with joy and happiness. Today, I am going to uncover the details on the Introduction to 2n4402. It is basically a PNP (Positive-Negative-Positive) silicon transistor where N doped layer lies between the two P doped layer. It consists of three terminals i.e. emitter, base, collector. Here N represents the base of the transistor and two P layers represents the emitter and collector respectively. I'm going to cover all aspects related to this transistor. Let's hop on the board and dive in the details of this silicon transistor.
Introduction to 2n4402
2n4402 is a bipolar silicon transistor, where one layer of N doped semiconductor is sand-witched between the two layers of P doped semiconductor.

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create Web Server with ESP8266 using SPIFFS.
We've already seen how to create a web server and how to provide an HTML page on our ESP8266. We use the PROGMEM command to store an HTML code in FLASH memory. For a simple page, this works fine, but what if we have a more complex webpage? With a better style? What if we want to include images?
Today we will learn how to use SPIFFS with ESP8266 to store files (regardless of type) in FLASH memory.
What is SPIFFS?
SPIFFS (SPI Flash File System) is a system designed for managing SPI flash memory in embedded devices. Its main goal is to use minimal RAM to access files. It's very useful when using pen drives ...
Hello friends, I hope you are happy, healthy and content. We have been discussing embedded systems lately and this discussion would be incomplete without an in-depth discussion on Real time embedded systems. You might have observed their utility and their absolute need in our constantly changing external and internal environment, the ease of managing the room temperature with a single tap, generating several results with a single click and streaming videos and playing games anytime and anywhere are the blessings of real time embedded systems.
Definition of Real Time Embedded Systems
Real time embedded systems can be defined as;
"The embedded systems which respond to real time situation with the help o ...
Hello friends, hope you all are fine and having fun. In today's post we are gonna have a look at LM317 Voltage Regulator in Proteus. In the previous post, we have seen how to design a 5V Power Supply in Proteus ISIS, which I have designed using IC regulator 7805. Today I am going to share How to design LM317 Voltage Regulator Circuit in Proteus. This DC power supply is a variable one means you can set its output voltage to any level you want. In order to change its output value we have used a variable resistor and by changing its value you can change the output value. It is a basic level project and very simple but used as a base to design large industrial projects. In this project, we are going to control the speed of a DC Motor and the correspon ...
