Hello everyone! I hope you all will be absolutely fine and having fun. In the tutorial Declaration of variables in MATLAB, I will elaborate you that how to declare different variables in MATLAB and how to manipulate those variables without assigning them with the values. Before going into the details of this tutorial you must go through Introduction to MATLAB, because understanding MATLAB first is better. This will help you in better understanding of this tutorial.
Variable declaration is one of the most important and compulsory steps while writing the code to perform any task. Without the declaration of the variables we can not proceed further to perform our task properly. So, if we want to do the different tasks in a proper way we must need to ...
Today we will talk about an extremely powerful tool in the use of microcontrollers. The Serial communication, specifically the USART (Universal Synchronous Asynchronous Receiver Transmitter) standard.
The system works using two wires. RX (Receiver) and TX (Transmitter), connecting two devices. The RX of one is connected to the TX of the other. If the choice is for a synchronous connection, it may be necessary to add one or two more pins to operate as a “traffic light”. But most current microcontrollers can operate asynchronously, which saves us the expense of pins. Data is sent, as the name implies, in a series of bits.
ESP8266 provides us with two ports, one of them converted to USB in the NodeMCU module.

Vacuum casting is the key technique for plastic or rubber part fabrication using a vacuum and stands out as a premier method for small batches of polyurethane products. This method is particularly valuable for the creation of samples of products so the manufacturer can assess the trend, market response, customer feedback, and product performance before working on full-scale production. Injection molding is another technique used for plastic model manufacturing, but vacuum casting is cost-effective and most suitable for small production. This article will shed light on the vacuum casting introduction, its working principles, pros and cons. Let’s discuss each point in detail.
Vacuum Casting Definition

Hello everyone, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to design a Smoke Detector with Arduino. Its quite a simple project but if you are working on any security project then you must add this feature in it. You should also download this Gas Sensor Library for Proteus, and design its simulation.
I will use gas sensor MQ2 for this project. I have purchased MQ2 Gas Sensor module as its quite easy to interface with Arduino. Arduino board I'm using is Arduino UNO. I have also designed an LPG Gas Leak Detect using Arduino using this MQ2 Sensor. So, let's get started with How to design Smoke Detector with Arduino & MQ2 Sensor.

Hello Readers! Today we'll talk about the , maintenance of water heater. To ensure that your home's heating system runs smoothly, you require multiple pieces of equipment. A water heater is of the most importance. Every household needs a water heater for numerous external and internal needs, such as the uninterrupted flow of warm water in the winters, washing tough stains off clothes, and sometimes cleaning and disinfecting surfaces with a mixture of warm water and antioxidants.
Since multiple parts of a water heater tank are in regular use, wear and tear are unavoidable. To ensure that your water heater lasts longer and continues to operate smoothly, read on. This article will take you through a heater's series of components, discussing a checkli ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I would like to provide a complete discussion on Ultrasonic Sensor Arduino Interfacing. I would like to tell you some detail about ultrasonic sensor, after that we will move towards ultrasonic sensor Arduino interfacing. Ultrasonic sensor is also known as SONAR sensor. SONAR basically stands for Sound Navigation and Ranging. Ultrasonic is mostly used for the distance measurements. It can also be used for measuring the depth of the sea.
I have already shared Ultrasonic Sensor Library for Proteus. Ultrasonic/SONAR sensor is an electronic device used to estimate the distance of an object by continuously transmitting sound waves at a particular frequency and listens to tha ...

Hello readers, hope you all are doing great. In this tutorial, we will discuss low power modes in ESP32, their purpose and their implementation to increase the battery life by reducing power consumption.
Purpose of Low Power Modes
Fig.1
Along with multiple wireless and processing features, ESP32 also provides us with a power-saving feature by offering sleep modes. When you are powering the ESP32 module from the live supply using an adaptor or a USB cable, there is nothing to worry about power consumption. But when you are using a battery, as a power source to ESP32, you need to manage the power consumption for longer battery life.
Low Power Modes in ESP32
When ESP32 is in sleep mode, a small amount of power is required to maintain the state of ...
