Imagine a real-time object counting system that is budget-friendly and easy to implement. You can achieve this goal with an ESP32-CAM. Today we will build an ESP32-CAM Object Counting System. This project is a combination of the power of embedded systems and computer vision.
The main processor of the system is ESP32-CAM, a budget-friendly microcontroller with an integrated camera. This tiny powerhouse captures live video streams and transmits them over Wi-Fi. On the other side, a Python-based application processes these streams, detects objects using image processing techniques, and displays the count dynamically.
Whether it’s tracking inventory in a warehouse, monitoring traffic flow, or automating production lines, this system is versatile and adaptable. You can implement this proje ...
In this tutorial, we will walk through the process of interfacing a pH sensor with an Arduino UNO in Proteus. To make the project more practical and user-friendly, an LCD is included so that both the sensor’s voltage output and the calculated pH value can be displayed clearly in real time. This allows the user to easily monitor the readings without needing additional software or serial monitoring tools.
The term pH, short for “potential of Hydrogen,” indicates the concentration of hydrogen ions (H⁺) in a solution and is used to determine whether it is acidic, neutral, or alkaline. A pH of 7 represents neutrality, values below 7 indicate acidity, and values above 7 represent alkalinity. Monitoring pH is essential in several fields—such as water quality testing, agriculture, food processing ...
Hello friends, I hope you all are doing great. In today's tutorial, we are going to have a look at what are Middleware in ASP.NET Core. It's our 3rd tutorial in ASP.NET Core series. In order to understand the Middleware, we have to open the Startup.cs file present in Solution Explorer.
In our previous lecture, we have discussed the Code in Startup.cs and I have told you thhat we will discuss the Configure method later, so now we have to understand that code first. So, first let's define middleware components and then have a look at that code:
Middleware in ASP.NET Core
Middleware in ASP.NET Core are simple software components used to control HTTP requests and handle both incoming requests as well as outgoing responses.
Each middleware is a se ...
Hello Friends, My name is Syed Daniyal Nasir. I hope you guys are fine and enjoying your lives with passion. Today, we are going to start the new series of tutorials related to Android Development and here's my first tutorial in thie series which is, Getting Started with Android. This is gonna be my first tutorial of Android Development for “The Engineering Projects”. As we all know, Android Development is enhancing vigorously day by day, Google Play Store is flooded with tons of new mobile applications each day. So a lot of people want to understand the basics of Android Development, so that they could develop their own applications. But some people find it very difficult due to certain reasons. That’s why we are going to make these tutorials as simple as possible, so that most of the peo ...
Hi readers! Welcome to the next article on the MQ series gas sensors. Today, our motto is to learn about the basic information of the MQ137 ammonia gas sensor. We know that ammonia gas is extensively used in industries, agricultural lands, Environmental Monitoring, Health and Public Safety, etc. In such areas, there are great chances of leakage that can be harmful and here, sensors like MQ137 are used for the instant detection of the Ammonia gas. It is a colorless gas with a distinct pungent smell and its inhalation may cause eyes, lungs, nose, and throat infections and irritation. So, the MQ137 is specialized for its detection and acts as a life savior in such cases.
In this article, we’ll commence our discussion with the basic introduction of the MQ137 ammonia gas sensor and will ...
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 everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation. If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons.
First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.).
Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly).
Because of these two reasons, we have to use the driver in between t ...
Hi Fellas! I am back to give you have a daily dose of valuable information so you keep coming back for what we have to offer. Today, I will discuss the details on the Introduction to PIC16F628a. It is defined as a self-contained 18-pin PIC Microcontroller that comes with memory, processor, peripherals and mainly used for embedded systems and applications.
Microcontrollers always remain a top priority for experts where automation is the main concern. Before the invention of microcontrollers, microprocessors were widely used for carrying out different functions related to industrial automation and processing applications. Both of them work identical in one way or the other, however, there are some exceptions i.e. microprocessors don't come with ROM ...
In advanced electronics and electrical systems, connectors play a crucial part in facilitating secure and dependable transmission among constituents. Among the multiple kinds of connectors utilized in electronics, the Molex connector is one of the most extensively identified and generally used. It is extremely prevalent in the hardware of the computer, automotive electronics, industrial equipment, and client electronic appliances. Molex connectors are recognized for their solidity, compact design, and ability to provide reliable electrical connections.Molex connectors are particularly famous in computer power supplies, automotive electronics, industrial machinery, and consumer devices because they supply dependable implementation, manageable facility, and long-lasting structure. Their conf ...
Hello, fellows, I hope you all are doing great. In today’s tutorial, we will discuss 5 Reasons to Get A Degree in The Engineering Field. Engineering represents the practical application of science and mathematics to find solutions to technical problems. Engineers don’t just sit back and watch. On the contrary, they design, invent, fix, improve, research, and so on. Engineers bring things to life, whether it’s physical buildings or robots.
If you want to create technology and products that make our lives easier, think about getting a degree in the engineering field. Not only is it one of the most popular college majors but also one of the most profitable ones. It might just be the right fit. These reasons will convince you that engineering is the b ...
