What is web 3.0 in simple terms? Web 3.0 has the potential to change the internet as we know it forever. You’re still early in catching the trend and building your first blockchain application, acquiring the skills to get a high-paying job, or creating your own web3 projects that can make you money. In Web 2.0 all the data is controlled by the Big Tech companies, such as Google, Apple, etc. In the decentralized web, no single person/company owns any data or information about anyone and everything is visible to the public. Web3.0, also known as the decentralized web, is the third and latest” ph ..read more

In this blog, we will learn how to make a fire alarm system using ESP8266 NodeMCU with the Blynk app, This is the IoT-based project to detects the nearby flame & notify on your Blynk app project.

In this blog, we are discussed how to measure distance using ultrasonic HCSR04 sensor and Arduino. Let’s take some information about the Ultrasonic HCSR04 sensor. To measure some distance we used it, but how it can work & measure the distance? That we will see in this blog. So, Ultrasonic sensors are used in a variety of applications. Our ultrasonic sensors made with piezoelectric crystals, use high-frequency sound waves to resonate with the desired frequency and convert electric energy into acoustic energy, and vice versa. In this what happened that Sound waves are transmitted to and ..read more

Hey guys, here is my next blog on LCD interfacing with ARDUINO. Most of the circuits of LCD Arduino projects we saw LCD interfacing, As we know that LCD stands for ‘Liquid Crystal Display’ play a very important role. It is used in different types of devices like in calculator, TVs, any advertising board, etc. The liquid crystal display uses the property of light monitoring of liquid crystal and they do not emit light directly. The LCD is a flat panel display or the electronic visual display. With low information, content the LCDs are obtained in the fixed image or the hidden like present words ..read more

Hey folk, in this blog we will discussed about interfacing LM35 temperature sensor with Arduino UNO. Introduction about LM35 temperature sensor: LM35 is a precession Integrated circuit Temperature sensor, whose output voltage varies, based on the temperature around it. It is a small and low-cost IC that can be used to measure temperature anywhere between -55°C to 150°C. LM35 PINOUT It can easily be interfacing LM35 with any Microcontroller that has ADC function or any development platform like Arduino. LM35 Temperature Sensor basically works on the principle of change in resista ..read more

In this blog, we will see the interfacing of the flame sensor with Arduino. Flame sensor, smoke sensors, fire alarm system, etc. are the safety devices that can be used at various places in the offices, institutions, homes, industrial applications, etc. which protect us from fire accidents. The flame sensor is easily available in the market as its result is good and due to cost efficiency. There are two types of flame sensors one having three pins and others having four pins respectively. Description about Flame Sensor: The flame sensor is an electronic device that is used to sense the fire or ..read more

Hey folks, welcome to my blog. Before we go ahead let me you guys why I had written a blog on this topic because I felt that there is a huge increase in usage of wireless devices and machines. So, it’s mandatory now to improve our skills in various wireless communication techniques. As a beginner, we can get started with the ESP8266 NodeMCU WiFi development board. We will also try to perform a small practice of LED blinking on our Node-MCU development board. Once you observed all the basics, I assured you that you will be more familiar with Arduino software and ESP8266 NodeMCU as well. In the ..read more

 In this blog, we have to make an audio amplifier using LM386 and study how to remove noise in an audio amplifier. It’s very simple and cheap. Step 1:- Circuit Diagram of audio amplifier using LM386 All this circuitry we have to make on a small mini breadboard. The circuit diagram or the connection of this setup is shown by using the sketch. Circuit Diagram of audio amplifier LM386 ✔ Hardware Requirements LM386 IC ————— Amazon Bread Board———– Amazon 3.5mm Audio Jack —- Amazon 1/4 watt Resister pack(1k Required) —— Amazon 8 ohm Speaker ———– Amazon 10K ohm variable ..read more

We will learn about HC-SR04  widely known as Ultrasonic Sensor, how it works, and how to interface with the NodeMCU. And also how to measure distance using ultrasonic sensor & ESP8266. Before building the circuit let me explain what is an HC-SR04 Ultrasonic sensor?? As the name indicates, ultrasonic sensors measure distance by using ultrasonic waves. But how? The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception. So there ends the ..read more
