Hello geeks, welcome to our new project. We are going to make an important project which will be very useful for us in our daily life which is a variable DC power supply. As engineers who work with electronics need different voltage ranges of DC power supply for different electronic projects and components. It becomes very clumsy and hard to manage different power supplies because of wires which are connected to it and each power supply consumes an extra power socket as well.
So in this project, we will overcome this issue and learn to make an adjustable DC power supply, in which we will get a wide range of voltages.
Software to install
We will make this project in the simulation, as it is a good practice to make any project in the simulation fir ...
Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer.
We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tuto ...
Hello Geeks, I hope you all are doing great and enjoying your festive seasons. This time, we have come up with a new project which will make your festival a bit brighter so here comes a Christmas tree.
It is said that Christmas is the center of all the celebrations. Did you guys know the scientist who discovered the light bulb, Thomas Edison and his friends were the first to put up the light bulbs on the Christmas tree, and here we are going to keep that tradition forward? Well, it’s time to gear up for the next season of Christmas being tech-savvy. Hence we have decided to brighten up a Christmas tree with the usage of Arduino Uno and LEDs in real life.
Software to Install:
To make our festival a little safer, we will first make our Christmas tree in the simulation and for that, we will ...
Hello readers, we hope you all are doing great. In this tutorial, we are going to demonstrate how to interface and control a servo motor using an ESP32 board. After that, we will demonstrate how to create a webserver to control the servo motor’s shaft position with the ESP32 board.
Servo Motors are among the most important actuators in robotics, with applications ranging from RC planes to automated door locks.
Hardware components required
A servo motor
ESP32 development board
Connecting wires
Breadboard
Servo Motor
There are several specific types of electric motor applications in which the motor must rotate only at a specific angle. For such applications, we need a special type of motor with such a special arrangement that causes the m ...
Hello geeks, welcome to our new project. In this project, we are going to make a very useful and interesting electronics tool that we as engineers or tinkers need in everyday life. We use the capacitor in most of our projects for various purposes such as filters or power supplies. Most of the time, we do not have a provision to measure the capacitor value in our digital multimeter. So, this time we came up with the solution. Hence, we will make our own capacitance measurement tool using Arduino.
Rather than investing in new electronic equipment, we will use an Arduino board and some basic components to measure the capacitance. To make this project, we should have some working knowledge about the capacitor. Here, we will not discuss the in-depth wo ...
We are familiar with multiple features of the ESP32 module. Like Wi-Fi capabilities, classic Bluetooth, Bluetooth low energy (BLE), inbuilt sensors etc.
Hello readers, I hope you all are doing great. We have already mentioned in our previous tutorials that, ESP32 is also featured with a Dual-Core Processor. Which provides better performance and efficiency.
In this tutorial, we will learn how to use ESP32’s dual cores. ESP32 has two (32-bit each) Tensilica Xtensa LX6 microprocessors namely, core0 and core1 which makes it a powerful dual-core microcontroller and hence stands apart from its predecessors.
When we compile and upload a code using Arduino IDE, we do not have to worry about which core executes the code. It just runs.

Hello readers, I hope you all are doing great. In our previous tutorial, we learnt how to make HTTP POST from ESP32 to the IFTTT server.
In this tutorial, we will learn about another application of the ESP32 module in the field of IoT (Internet of Things). We can publish multiple sensor readings from ESP32 to Google sheets via the IFTTT web service.
IFTTT is used as a third-party web service to integrate Google sheets with ESP32.

Creating an IFTTT Account for Integrating ESP32 with Google Sheets
We are going to create an applet (on the IFTTT server) that is responsible to integrate the Webhooks and Google Sheets services.
While operating with the IFTTT server there are some services/utilities that we are going to deal with like Applets an ...
Industrial workplace health and safety are essential for avoiding work-related accidents, injuries, and fatalities. In fact, as many as 13,455,000 workers across manufacturing industries in the US are at risk for fatal and nonfatal injuries, the CDC reveals. Not only does improving workplace health and safety protect workers, but it also prevents lost work days and lost revenue. The National Safety Council found work injuries cost businesses a total of $161.5 billion annually, equating to $1,100 per worker.
Improve employee training
New workers are three times more likely to sustain an injury in their first month than workers with a year's experience on the job. By improving employee training and tailoring programs to the demands of each individu ...
ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on another ESP32 application in the field of IoT.
Hello readers, I hope you all are doing great. In the previous tutorial, we learned how to send sensor readings from ESP32 to the cloud (ThingSpeak webserver).
In this tutorial, we will learn to send HTTP POST requests from the ESP32 board to ThingSpeak and IFTTT APIs.
What is HTTP?
Fig. 1 Hypertext Transfer Protocol
HTTP stands for hypertext transfer control and it is a protocol for transferring data between a web client and a web server. Hyper text transfer protocol was invented alongside HTML (Hypertext markup language) to create the first interactive, text-based web browser: the original www or World Wid ...
Hyperconverged infrastructure becomes the go-to option for enterprise-level companies and startups looking to scale fast. While server virtualization is a mature technology, HCI continues to be one of the hottest trends in the IT industry right now. HCI offers businesses improved reliability, reduced deployment time, lower maintenance costs, and easy scalability.
