Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at the Introduction to 20x4 LCD Module. The LCD stands for liquid crystal display, which works on the light modulation features of liquid crystals. It is available in electronic visible display, video display and flat panel display. There are numerous categories and features are exist in markets of LCD and you can see it on your mobile, laptop, computer and television screen.
The invention of LCD gives new life to electronic industries and replaces lED and gas plasma techniques. It also replaces the CTR (cathode ray) tube that is used for visual display. The input power consumed by the liquid crystal display is less than the light-emitting diode and plasma display. In today's post, we will have a loo ...
Hello friends! I hope you all had a great start to the new year.
In our first lecture, we had looked at the MATLAB prompt and also learned how to enter a few basic commands that use math operations. This also allowed us to use the MATLAB prompt as an advanced calculator. Today we will look at the various MATLAB keywords, and a few more basic commands and MATLAB functions, that will help us keep the prompt window organized and help in mathematical calculations. We are also going to get familiar with MATLAB’s interface and the various windows. We will also write our first user-defined MATLAB functions.
MATLAB keywords and functions
Like any programming language, MATLAB has its own set of keywords that are the basic building blocks of MATLAB. These 20 building blocks can be called by simply ...

Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, a facial recognition system on a Raspberry Pi 4 was used to develop a smart security system. We also learned how to create a dataset using two Python scripts to train and analyze a series of photographs of a certain person. This tutorial will teach you how to install pi-hole on a Raspberry Pi 4 and use it to block advertisements from anywhere. This is a great initiative for folks who are tired of annoying pop-up adverts while browsing. First, we'll learn how to set up the pi-hole without the need for an environment, then we'll use Docker to install pi-hole, and ultimately we'll see how we can access it from anywhere.

There is no escaping from the fact that cutting-edge technological developments and evolving market innovations are pushing 3D printing into the mainstream. According to experts, the 3D printing market is expected to become a multi-trillion-dollar industry. It will rise from a $ 5 billion market to $55.8 billion by 2027. This is enough reason why many industries have started to embrace it. The 3D printing market has gained popularity due to the maturing business environment. And now that all sorts of businesses have picked pace after COVID-19, the 3D market has become quite a rage. And the market continues to experience massive success among home users and hobbyists. The number of 3D printers has doubled in the last few years. However, the combined value of the overall industrial/c ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to BC547. It is an NPN bipolar junction transistor (BJT), mainly used for switching and current amplification.
Its maximum current gain is around 800. So, let's have a detailed overview of BC 547.
Introduction to BC547
BC547 is a 3-Terminal NPN Bipolar Junction Transistor(BJT), mostly used for switching purposes and current amplification.
BC547 Pins(Terminals) from left to right are called:
Collector.
Base.
Emitter.
Depending on the voltage applied at Base Terminal, BC547 can operate in two states, named:
Forward Biased.
Reverse Biased.
BC547 as Reverse Bias ...
Hello friends, hope you all are having fun and enjoying life. In today's post we are gonna see how to send data to serial port in MATLAB. Its a requested tutorial, asked by a follower and after giving him the code, I thought to share it on our blog so that others could also get benefit from it. We have discussed serial port many times and have seen how to communicate with it using different software but we haven't yet discussed how to send data to serial port in MATLAB. So, in today's post I am gonna share the complete code for sending data to serial port in MATLAB.
Serial port is most common way of communication, we can send or receive data using serial port. Normally, in engineering projects there's a need to send or receive data from microcontr ...
Hello friends, I hope you all are well. Today, we are going to share the second version of the Solar Panel Library for Proteus. You should also have a look at the first version of the Solar Panel Library, which we have posted around 2 years back and we were receiving suggestions to reduce its size as there's less space left for other components.
That's why we have designed this new Solar Panel Library and have reduced the size of the solar panel. We have also added a new black solar panel component to it. So, this library contains 2 solar Panel modules in it. First, let's have a look at a brief introduction to Solar Panel and then will download the Proteus Library zip file.
What is Solar Panel?
Solar Panels are designed using solar cells compos ...
Hello friends, hope you all are having fun with your lives. Today, I am going to share links related to PLC projects. I have shared few PLC projects on my blog so here on the post I am gonna compile a list and will post all the PLC projects posted till now. I will keep on updating this list so stay tuned.
All the PLC projects posted here are completely designed by our team so if you wanna copy them then you are most welcome but do mentioned the link of respective project as a favor. Its not a very big list rite now but I am gonna update more projects real soon and will update the list. So, let's get started with PLC projects:

Hello readers, hope you all are doing great. In this tutorial, we are going to discuss a mechanism that allows users to update the ESP32 with a new program wirelessly or over the air (without using a USB cable to upload a new program).
Over-The-Air (OTA) programming
Fig. 1 ESP32 OTA
OTA programming is the mean by which a product manufacturer or product service provider can update the features or functionality of the device wirelessly or over the air, after the device has been deployed in the field where connecting a cable or uploading the code serially is difficult.
One key advantage of OTA is that a single central node can send an update to multiple ESPs on the same network.
The device must have a provisioning client capable of receivin ...
Hi Everyone! I hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to MID400.The MID400 is an 8-pin optically isolated AC line-to-logic Power Line Monitor Optocoupler. The AC line voltage is detected by two back-to-back LEDs that are connected in series with an external resistor. When this device identifies the AC voltage, the output pin goes low and when there is no AC voltage detected, it remains high.
This feature of detecting the AC line voltage is widely employed in AC to DC control and relay latching applications. I suggest you buckle up as I’ll walk you through the complete introduction to MID400 covering datasheet, pinout, features, equivalents, and applications. Let’s dive right in.
