Hello readers, I hope you all are doing great.
ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on one of the ESP32 applications in the field of IoT.
Project Overview
In this tutorial, we will learn how to update LCD display with new data or input using a web server created with ESP32.
Fig. 1
To achieve the target, we will be using an HTML (Hypertext Markup Language) form to provide web input and then update the text displayed on LCD. The values or input received from the webserver will be further stored inside a variable in the code for further use (to display on LCD).
We have already posted a tutorial on LCD (Liquid Crystal Display) interfacing with ESP32. In that tutorial, we demonstrated how to displa ...
Hey Guys! Hope you’re well. I welcome you on board. In this post today, I’ll walk you through PCBA (Printed Circuit Board Assembly) in detail. It's our 4th tutorial in the PCB learning series.
In the 1st tutorial, we studied printed circuit board(PCB) in detail and learned that PCB provides physical support and electrical connection through conductive copper layers for the electronic components placed on the board. We have seen in our previous tutorials that when we place our PCB order on some PCB fabrication house, they provide us with a PCB board without electronic components. We have to solder the electronic components on the board. But now these PCB companies also offer a service to provide finished PCB boards with electronic components attach ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a new project in which we are gonna do Arduino Bluetooth communication. The Bluetooth module I have used for this project is HC-05, which is a serial Bluetooth module. We can quite easily perform the Bluetooth communication with this module using Arduino board. I have worked on many projects in which I have to send the data from sensors to my computer via Bluetooth. So, in such projects I normally use this Bluetooth module which is connected with the sensors and then Arduino gets the data from these sensors and then send this data to computer via Bluetooth module. In this project, I have used Arduino board but you can use PIC Microcontroller or 8051 Mic ...
Hello Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to IRF730.
The IRF730 is an n-channel MOSFET where major charge carriers are electrons and conduction in the transistor is carried out due to the motion of these electrons. It comes with a TO-220 package where the drain-to-source breakdown voltage is 400V and power dissipation is 100W.
I suggest you read this post all the way through as I’ll be discussing the complete Introduction to IRF730 covering datasheet, pinout, features, power ratings, equivalent, and applications.
Let’s jump right in.
Introduction to IRF730
The IRF730 is an n-channel MOSFET mainly used for switching and amplification applications in the electrical ...
Hello folks, I hope things are proceeding great at all of your sides. Today I am going to discuss the evolution of PCB (Printed Circuit board) in 2019.
You all must be already aware of the term PCB, what printed circuit board is? In case you are a newbie and don’t have much information about it. Then no problem, because I am going to share the history, the evolution of Printed circuit board (PCB) and when it first comes into usage?
What is PCB?
The printed circuit board mechanically support and connect to electronic components through the use of conductive tracks, pads, and other features.
Alright, lets me explain you in simple words.
PC boards are internal components that transmit electronic signals through electronic devices. For example: wh ...
Hi Pupils, Welcome to another Experiment of Proteus at The Engineering Projects. Previously, we saw what are the Junction Field Effect Transistors. Today we'll learn about some of the applications of Junction Field Effect Transistors.
Just before the Experiment, it is useful to revise that:
Transistors are three terminal, unipolar Devices. The terminals of Junction Field Effect Transistor are named as :
Drain
Source
Gate
The Gate Terminal is common to both Source and Drain.
Prior to start, let's clear some Concepts about Junction Field Effect Transistor.
Resistor
Resistor is an electrical device. we define the resistors as:
"A Resister is a two terminal Passive electrical device that shows the electrical resistance and is useful in almos ...

Hello folks, I hope you are doing great in your life. In today’s tutorial, I am going to talk about “For Loop In JavaScript”. This is our 7th tutorial of the JavaScript series.
Loops are designed in JavaScript to automate the repetition task. You may have encountered a lot of time in programming that you have to repeat an action again and again. To help you in reducing the number of lines code and time, loops were created.
There are five types of loops JavaScript have:
For Loop
For...In Loop
For...of Loop
While Loop
Do While Loop
For Loop in JavaScript
For Loop will run the same code of block again and again repeatedly, for a specific number of time or as long as a certain condition is met.
The For loop of JavaScript is similar to ...
Hello everyone, today I am going to share Stepper Motor Control using PIC Microcontroller. We are all quite well aware of stepper motor but if you don't have much of the idea about this motor then you should give it a google search. :P Stepper motor is used in such projects where precise movement is required. Projects where we need to move the object at some particular angle. Stepper Motor works on electromagnetic phenomena. Electromagnets are present in the stepper motor and when we supply voltage across them, these electromagnets got polarized and produce a magnetic field and in order to depolarize them, what we need to do is simply depolarize these electromagnets. We all know that in motors, we have rotor and stater so in stepper motor these el ...
Hi readers! Hopefully, you are well and exploring technology daily. Today, the topic of our discourse is the MLX91218 and MLX91219 3.3V/5V sensors with high-accuracy simplify inverter/converter control and battery management. You might already know about it or something new and different.
The Melexis MLX91218 and MLX91219 are magnetic field sensors that are of very high accuracy and are used in applications such as inverter/converter control and BMS. They possess an excellent quality level of accuracy in magnetic field sensing while consuming low power. They are, therefore, one of the best choices for modern electronic applications such as electric vehicles, industrial automation, renewable energy systems, and consumer electronics.
The 3.3V or 5V wide range of voltage supply offers broa ...
