Hello friends. We hope you are doing fine. The world is full of colours. Isn’t it? We humans can see and differentiate the colours very easily. But teaching robots and AI apps about colours is a real challenge. With the advancement of computer vision and embedded systems, this task has become easier than before. Today, we are going to make an RGB colour identifier using the ESP32-CAM. This project combines the power of OpenCV with the ESP32-CAM module to create a simple but effective system for detecting and tracking basic colors in real time.
System Architecture
1. Overview
This system consists of an ESP32-CAM module acting as a live-streaming camera server and a Python-based computer vision application running on a remote computer. The Python application fetches images from the ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to interface the BMP280 sensor with the ES32 module to get temperature, pressure and altitude readings. Later, in this tutorial, we will also discuss how to upload these sensor readings to a web server.
BMP280
BMP280 or Barometric pressure sensor is a module used to measure temperature pressure and altitude. The small size and low power consumption feature of this sensor makes it feasible for battery-powered devices, GPS modules and mobile applications etc.

The BMP280 is the product of BOSCH which is based on Bosch’s proven Piezo-resistive pressure sensor technology featured with high accuracy, long term stability, linearity and high EMC robus ...
Introduction
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.

Hey Fellas! Hope you are doing great. Today I am going to give you the details on Introduction to 2n5320. It is basically a Bipolar NPN (Negative Positive Negative) Transistor (BJT), which contains two layers of N-doped semiconductor and one layer of P-doped semiconductor. P, layer lies between two N layers. Here P represents the Base of the transistor and two N layers show emitter and collector respectively.
This NPN transistor has a wide range of applications. It is mainly used for power amplification and switching purpose.You should also have a look at Introduction to BC547 which is also an NPN transistor. So, let's get started with Introduction to 2n5320:
Introduction to 2n5320
2n5320 is a bipolar Switching Silicon transistor, which is mo ...
I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to ESP-01. ESP-01 is an inexpensive, small-sized WiFi module, which consists of TCP/IP stack along with a built-in microcontroller. So, we can directly program this small chip and can bring WiFi capability in our Embedded projects. When first time this ship came into the market in August 2014, it got a lot of attention by users. The main reason for it to seek attention is that this module allows the microcontroller to connect with a WiFi available (and programmed to connect) and it follows Hayes Style Commands and develops a TCP/IP network.
ESP-01 chip integrates an antenna, RF balun, power amplifier, filters, and power arrangement module. ESP-01 is used in industry and many projects a ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at Flow Switches And Flow Meters. There are a lot of flow meters and flow switches types on the market today. Thus, it is sometimes troublesome to choose the ideal device for your demands.
So, why is learning the different types of flow meters and flow switches, as well as their differences, essential? You might wonder why you need to know about this. Well, it is necessary to understand how flow switches differ from flow meters as this impacts your business. There is a lot to consider in choosing the right fit for you and not knowing how it works might cost you another expense.
When you are choosing flow meters and flow switches, it is essential to know ...
Hi Friends! I welcome you on board. Happy to see you around. In this post today, I’ll detail the Introduction to CA3162.The CA3162 is a monolithic A/D converter, offering a 3-digit multiplexed BCD output. It comes with an ultra-stable internal band-gap voltage reference. With differential input, this device provides a choice of low-speed (4Hz) or high-speed (96Hz) conversion rate. It is a 16-pin device that provides dual slope A/D conversion.
I suggest you buckle up as I’ll walk you through the complete Introduction to CA3162 covering datasheet, pinout, features, and applications. Without further ado, let’s get started.

Oil platforms represent some of the most challenging and potentially hazardous work environments on Earth. These massive structures, standing alone in vast expanses of ocean, house hundreds of workers who extract petroleum from beneath the seabed. The question of safety on these installations is complex, involving multiple layers of risk management, regulatory oversight, and technological advancement
that have evolved significantly over decades of offshore drilling operations.
Understanding the Risks
Offshore oil platforms face unique safety challenges that distinguish them from land-based industrial facilities. The marine environment presents constant threats from severe weather conditions, including hurricanes, storms, and high seas that can damage equipment and endanger personnel. T ...
What Is MIG Welding?
MIG welding is the process of joining metal parts by melting the base metal and fusing it with a filler metal. The name is derived from the phrase "Metal Inert Gas," which is commonly used. The process involves using an arc between an electrode and the workpiece, which melts the base metal and fuses it with the filler metal.
Mig welding is an extremely versatile process that can be used to create virtually any shape or configuration of the welded joint. You can also use it for many different metals, including low carbon steel, stainless steel, and aluminum alloys.
Mig Welding Equipment
The MIG welding equipment you'll need includes:
Torch
The torch supplies the heat needed to melt the wire. It has a handle, an on/of ...
Hi Guys! Hope you’re well today. Thank you for clicking this read. In this post today, I’ll walk through Cloud Computing Advantages.
Growing a business requires keeping up with modern technologies. And cloud computing is no different. Even though it’s not a new term and has been around for a long while, it still encompasses a huge potential to effectively run and manage business operations. Cloud computing is the provision of computing resources over the internet. These resources include storage, processing power, and databases.
Integrating more technologies (like IoT, AI) into the business models means it opens up opportunities to produce a large amount of data. And it’s very challenging to store and process that data on on-site data centers. Th ...
