Hi Geeks, welcome to our new project. Our new project is one of the most common issues you’ve seen in your cities. In this project, we are going to make a car parking system with automatic billing. In the entire world, there are an estimated 1.4 billion cars on the road, which is absolutely great news if we are considering the development of the Automobile industry. But the most serious issue is that the number of cars exceeds the number of available parking places, resulting in traffic congestion. Damaged cars due to this lack of space, fewer parking locations, lack of parking signage, informal parking, and overcharging for parking are just a few of the issues.
People are still choosing manual parking methods, which have a number of drawbacks, suc ...
Hello everyone, welcome to today article which we are going to have a look at how technology has evolved the online casino industry. Some of you might be having knowhow on what casino industry is and some might be having partial or no knowledge at all. So, we are going to start with simple things as we advance our topic of discussion further. You should also have a look at the Technology behind Online Casinos.
Definition of the global casino industry
The global casino industry is an industry that is made of facilities that involves predictions of outcomes of the final result that will be obtained after an invent has passed. The predictions are made before the event has started. It is made up of the gambling activities such as the gaming machines ...
Hello readers, I hope you are all doing great. In this tutorial, we are going to discuss the OTA web updater on the ESP32.
We already covered the fundamentals of OTA programming in ESP32, in our previous tutorial where we used the Arduino IDE to upload OTA code into the ESP32 module using the network port.
In the OTA web updater, you need to create a web server page for OTA programming.

"Over-the-air" refers to the ability to wirelessly download an application, configuration, or firmware to internet-enabled devices, also known as IoT. (OTA). It functions similarly to our computers, laptops, tab ...
Hello friends, I hope you are doing very well! In today's tutorial, we will set up a simulation environment for Ladder Logic Programming. It's our second tutorial in Ladder Logic Programming Series. In our previous tutorial, we have seen a detailed Introduction to Ladder Logic Programming and we have seen that this programming language is used for PLC controllers.
As PLC is an Industrial Controller, it comes with built-in relays/transistors(with protection circuitry) and thus is quite expensive as compared to microcontrollers/microprocessors i.e. Arduino, Raspberry Pi etc. Moreover, if you are working on a real PLC, you need to do some wiring in order to operate it. So, in order to avoid these PLC issues at the beginning, instead of buying a PLC o ...
Greetings and welcome to today’s lecture. It's our 7th tutorial in the PCB learning series. In our previous lectures, we have studied the two main types of PCB i.e. Single-sided and Double-sided PCB. Today is going to be a very interesting and interactive class about Through Hole Technology(THT), which is applied in the process of designing printed circuit boards.A PCB board has a properly designed circuit on it and it's composed of connecting traces/paths and various electronic components. The electronic components are mounted on the board in two different ways i.e. Through-hole and Surface-mount. We will cover Surface-mount in our next lecture and today, we will discuss how to mount components on PCB boards using though-hole technology.So, let's ...
Hello! Readers, I hope you are pretty good. I am here with a new article to enhance your knowledge about advanced technologies. Today, we will have a detailed overview of the Manufacturing Process of Multilayer PCB. First, we will have a look at its basic definition, why there Is a need for this new type of PCB in presence of single layer and double layer PCBs. What are the merits and demerits of multilayer PCBs and pedagogy behind the construction process of these PCBs? Let’s start to take in all information about these PCBs. I try my best to deliver all of my research capacity for doing this job.
Introduction to Multi-layer PCBs
As to the name, it's clear that multi-layer PCBs are those which have several conductive layers over substantial material which is knowns as substrate. Unlike ...
Hello readers, today we will learn about the messaging protocol supported by ESP32(called MQTT protocol), which is used for IoT applications. The communication protocol to be used for data transmission and connectivity in web-enabled devices depends upon the type of IoT application.
The Internet of Things (IoT) is a network of interconnected computing devices like digital machines, automobiles with inbuilt sensors, having unique identifiers and the ability to communicate data over a network without the need for human intervention.
Before implementation, let's first have a look at what is MQTT Protocol?
What is MQTT?
MQTT stands for Message Queuing Telemetry Protocol and is a messaging or communication protocol used for IoT applications.
In MQ ...
Hello everyone, I hope you all are doing great. Today, we are going to share the 9th chapter in the PCB learning series, where we will have a look at the difference between Through-hole and Surface-mount technology.In our previous lectures, we studied both THT and SMT methods separately and have seen that both are used for components mounting on the PCB board. So, today, we will have a look at the difference between the two techniques. So, let's get started without wasting any time.
Through-Hole vs Surface-Mount
Let us know have a look at these differences and get to know the way forward when it comes to the process of component selection whether SMT or DIP.
Definition - THT vs SMT
THT stands for through-hole technology.
In Through-hole technology, components are mounted by ...
PWM stands for Pulse-Width Modulation. Once the switching frequency (fsw) has been chosen, the ratio between the switch-on time (TON) and the switch-off time (TOFF) is varied. This is commonly called duty-cycle (D). The duty cycle can be between 0 and 1 and is generally expressed as a percentage (%).
D = TON / (TON + TOFF) = TON x fsw
The variation of the pulse width, made at a high frequency (kHz), is perceived as continuous and can be translated into a variation of the rotation speed of a motor, dimming a LED, driving an encoder, driving power conversion, and etc. The use of PWM is also widely used in the automotive sector in electronic control units (ECU - Electronic Control Unit) to manage the energy to be supplied to some actuators, both fix ...
Choosing a prototyping firm to manufacture your things is a crucial decision. Identifying the right match is a difficult task for any firm. Cost, effectiveness, dependability, and operational processes must all be considered before assigning any production assets.
Dealing with a prototyping firm should be straightforward once you learn what to look for. The following are important considerations to consider while looking for a producer to help you bring your prototype idea to life.
Familiarity with the Business
You can look through the portfolios of the best prototyping businesses to see their previous work. This data is crucial in determining whether they have experience with similar initiatives and specialize in your required prototypes.
