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 everyone! I hope you all will be absolutely fine and having fun. Today, I will provide you document on detailed discussion about Introduction to LM224. LM-224 has four internal builtin operational amplifiers. These amplifiers are frequency compensated. The basic purpose to design these type of device is to operate it from a single power supply sources. Moreover, they are also able to perform different tasks using split power supplies. Magnitude of power supply and the current current drain both are independent of each other.
LM-224 has a very wide range of application areas which include DC gain blocks, transducer amplifiers etc. LM 224 has a large number of amazing features include wide power supply ranges, large bandwidth, low input offs ...
In today’s post, as the name suggests, we will see how to get data from online webserver using Arduino Wifi in simple steps. Getting data from web server using Arduino Wifi Shield has always remained a problem for the engineers. Its not much difficult task as its usually considered to be. In today’s post, I will create a small project in which I will control two simple LEDs via online web server. It’s really a very interesting project and when I completed it, I felt like Hurrah!!!
Arduino Wifi Shield is used to connect Arduino board with Wifi. After connectivity with Wifi, one can perform many tasks using this shield. We can built a complete server on it and can also use it as a client. Server designed on an Arduino Wifi Shield are usually quite si ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to TDA7294.
TDA7294 is a monolithic class AB power-based audio amplifier that comes with a DMOS output stage. It is primarily used for the amplification of audio signals in Hi-Fi field applications containing self-powered loudspeakers. The fault protection circuitry used in this device protects against short circuits.
I suggest you read this post all the way through, as I’ll detail the complete introduction to TDA7294 covering datasheet, pinout, features, and applications.
Let’s get started.

Hey Fellas! Hope you are doing great and having fun in your lives. We always try to keep you updated with useful information that resonates with your needs and expectations so you can grow and excel in your relevant field. I am back to give you a daily dose of useful information that may help you resolve your queries and problems related to engineering and technology field. Today, I am going to unlock the details on the Introduction to 2n6547. It is an NPN bipolar junction transistor that comes with high voltage and current capability and fast switching speed, mainly used in switched mode power supplies and flyback and forward single transistor low power converters. I'll try to cover each and everything related to this NPN transistor, so you don't ...
Hello friends, I hope you all are fine and having fun with your lives.Today I am not gonna post a new topic or tutorial, instead I am going to arrange all my Arduino Projects and tutorials in this post, as its better to have all of them in one place. I recently posted a PIC Microcontroller Projects post and it was highly appreciated by the followers so I thought to do the same with Arduino as well because I have posted more Arduino projects as compared to PIC Microcontroller.
I will post all the Arduino Projects & Tutorials links below in sequence i.e. from easy to pro level so if you are a new user and want to get command over Arduino projects then read all of them one by one. Moreover, I will also keep on updating this post whenever I am go ...
Hi Friends! Glad to see you here. I welcome you on board. In this post today, I’ll be discussing the Introduction to BC327. BC327 is a bipolar junction transistor that falls under the family of PNP transistors. It is composed of silicone material and is used to drive load under 800mA. It’s a current-controlled device that carries three pins where small current generated at the one terminal is used to control large current at the other terminals. Read this post all the way through as you’ll get to know all nuts and bolts of BC327 covering pinout, working, power ratings, applications, and physical dimensions.
Let’s get started.

Hello friends, hope you all are fine and enjoying in your life. In the previous post, we have seen How to use Oscilloscope in Proteus ISIS, today I am going share a new and a very important Tutorial which is How to Design a 5V Power Supply in Proteus? This project is very simple and of basic level but importance of this project is that it is used as a base in almost all large electronics project, designed now-a-days. When I start working on any project then the first thing, I need to design is this DC power supply, because without powering up the components, we can't use them. :)
While designing a 5V Power Supply in Proteus ISIS, we will be using Voltage Regulator IC, which is commonly known as 7805. This voltage regulator is used to regulate or c ...
