Hello friends, I hope you all are doing great. Today, we will create a web server with ESP8266 microcontroller to control the activation of an LED. The goal is to understand how the ESP8266 connects to a WiFi network, how it sets up a web server, and how it is possible to exchange information between the browser and the esp8266.
Components Required
1x Computer/notebook with Arduino
1x Mini-USB cable.
1x NodeMCU (ESP8266 Breakout Board)
Internet Browser (Chrome, Firefox, IE…)
ESP8266 Libraries for Arduino IDE
For this project, we will use two libraries:

Hello Friends! I aspire you a very happy life. Whenever you come over and visit our site, we feel happy to keep you updated with relevant information that can help resolve your questions and queries. Most of the hobbyist and students take interest in electronic devices and components that are the building blocks of electronic projects. Today, I am going to uncover the details on the Introduction to DG408. It is a multiplexer, also known as data selector, that comes with 8 channel input, in which of one the eight inputs is connected to the common output for the transmission of data over network in a specific bandwidth and time. It is an ideal choice for audio signal routing and single supply system. I'll discuss each and everything related to this ...
Hello readers, Welcome to another tutorial about the signal and system. In this lecture, you are going to read details about the ramp response of a signal. In the past lectures, we have been dealing with different types of responses of LTI systems, and therefore, we know that linear invariant systems, or LTI systems, are those which follow the rules of linearity and are also time-invariant. So, at present, our focus is to examine what happens when the ramp signals are fed into the LTI system and which type of output signal we receive. Here is a glimpse at today’s topic that we will learn deeply.
What is the RAMP signal?
How can you define the ramp response?
How to use the ramp function in MATLAB to get the ramp response?
What are some important properties of the ramp function?
How i ...
Hi Friends! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll detail the Introduction to SB560.
The SB560 is a Schottky diode, also known as a hot-carrier diode, mainly incorporated in extremely fast switching applications. It comes with low forward drop voltage and is used in the high-frequency operation. A highly reliable and efficient device, SB560 is a high forward surge capability component available in the DO-201AD package. This device carries a maximum RMS voltage of 42V while the maximum repetitive peak reverse voltage is 60V.
I suggest you go through this entire post till the end, as I’ll detail the Introduction to SB560 covering datasheet, pinout, features, and applications.

Hi Fellas! Hope you’re doing well today. I welcome you on board. In this post today, I’ll detail the Introduction to 2SD882.
2sd882 is an NPN bipolar junction transistor used for amplification and switching purposes. It is a semiconductor device composed of silicon material and comes in the TO-126 package. As this is a bipolar transistor, here conductivity is carried out by two charge carriers i.e. electrons and holes where electrons are major charge carriers and holes are minority carriers. During the amplification application, the small input current across one pair of terminals is used to produce a large output current across other pairs of terminals.
In this post, I’ll walk you through the working principle, pinout, power ratings, alternat ...

The Internet of Things ( or IoT) is a network of interconnected computing devices such as digital machines, automobiles with built-in sensors, or humans with unique identifiers and the ability to communicate data over a network without human intervention.
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send sensor readings from ESP32 to the ThingSpeak cloud. Here we will use the ESP32’s internal sensor like hall-effect sensor and temperature sensor to observe the data and then will share that data cloud.
What is ThingSpeak?
Fig. 1: ESP32 ThingSpeak
It is an open data platform for IoT (Internet of Things). ThingSpeak is a web service operated by MathWorks where we can send sensor readings/data to the cloud. We ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Introduction to PT2272. It is a CMOS (complementary metal-oxide-semiconductor) that use to design simple wireless controlling of instruments installed at some distance. This module is normally used for controlling the circuits of garage door, speed control of the fan, robots and for monitoring the alarm connected at different places for security purposes.
This integrated circuitry uses non-variable code address and no built-in encryption due to these parameters it not used for such circuits where high security is need but uses only for small or less cost security circuits such as used in home security alarms etc. In today's post, we will have a look at its w ...
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.
