Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explore my knowledge about Introduction to LM317. It is basically a positive voltage regulator having three terminals. It can a supply a current more than 1.5A and voltage in a range of 1.25V to around 37V. You should also have a look at this LM 317 Calculator.
For the adjustment of output voltage only two external resistors are required. It has improved standards of line regulation as well as load regulation. Full overload protection e.g. current limiting, area protection can be achieved using LM317. If its adjusting terminal is disconnected, even then all of the protection circuits will work properly. We can also use LM317 as precision current regulator ...
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, we hope you all are doing great. Welcome to the 1st lecture of Section 4 in the ESP32 Programming Series. In this section, we will interface the ESP32 module with common Embedded modules(i.e. LCD, Keypad, RTC etc.).
In today's tutorial, we will interface ESP32 with a 16x2 LCD and will display data using both Data Mode and I2C Mode. LCD is the most commonly used embedded module in IoT Projects. It is used to display different types of data i.e. sensor readings, warning messages, notifications etc.
Before going forward, let's first have a look at what is LCD and How it works:
16x2 LCD Module
LCD(Liquid Crystal Display) is a type of electronic display module that is used in a wide variety of applications and devices such as calculators, computers, mobile phones, ...
Hello readers, I hope you all are doing great. In our previous tutorial, we learnt how to make HTTP POST from ESP32 to the IFTTT server.
In this tutorial, we will learn about another application of the ESP32 module in the field of IoT (Internet of Things). We can publish multiple sensor readings from ESP32 to Google sheets via the IFTTT web service.
IFTTT is used as a third-party web service to integrate Google sheets with ESP32.

Creating an IFTTT Account for Integrating ESP32 with Google Sheets
We are going to create an applet (on the IFTTT server) that is responsible to integrate the Webhooks and Google Sheets services.
While operating with the IFTTT server there are some services/utilities that we are going to deal with like Applets an ...
Hello Friends, I hope you all are fine and will be doing well in your life. In today's tutorial, I am going to give you a detailed Introduction to DHT11. It is an embedded sensor used to measure temperature & humidity in the surroundings and gives calibrated digital output. It can measure temperature in the range of 0°C to 50°C with ±2°C accuracy. Its humidity range is from 20% to 80% with ±5% accuracy. It is a small, low cost and easy-to-interface embedded sensor.
In this tutorial, I will explain its working, pinout, protocol and interfacing with other microcontrollers in detail.
Here are a few important features of DHT11, given in the below table:

Hi Guys! Hope you’re well. In this post today, we’ll cover What is IGBT? We’ll also discuss IGBT Full Form, Pinout, Meaning, Symbol & Working.BJT (bipolar junction transistor) and MOSFETs (metal-oxide-semiconductor field-effect transistor) are commonly used electronic switches that we’ve already studied in detail. These devices are useful when you deal with low-current applications, however, when it comes to high-current applications, these devices don’t work as expected. This is where the IGBT transistor comes in handy. This device is a combination of both BJT and MOSFET and stands fit for high-current applications.
In this post, we’ll cover What is IGBT in detail.
Let’s get started:1. What is IGBT?
IGBT is a three-pin device made of semiconductor material and is used for fast- ...
