Hello readers, I hope you all are doing great. Welcome to Section 5 of the ESP32 Programming Series. In this section, we are going to interface different Embedded Sensors with the ESP32 Microcontroller Board. ESP32 development board is featured with some inbuilt sensors(i.e. hall effect sensor, capacitive touch sensor) so, in the initial tutorials of this section, we will explore these built-in ESP32 sensors and in the later lectures, we will interface third-party sensors with the ESP32.
In today's lecture, we will discuss the working/operation of the ESP32 built-in Hall Effect Sensor. Hall Effect sensor is used to detect the variation in the magnetic field of its surroundings. So, let's first understand What's Hall Effect:
What is the Hall Effect?
The Hall Effect phenomenon was fir ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of you about how to make a simple program for DC Motor Direction Control in LabVIEW. In my previous tutorials, I have also worked on DC Motor Direction Control using Arduino. You should go through these tutorials they will be helpful in better understanding of the tutorial DC Motor Direction control using NI LabVIEW. The word DC is basically an abbreviation of Direct current. So, a direct current motor is commonly used motor having two input terminals, one is positive and the other one is negative. If we connect these terminals with the voltage supply the motor will rotate. If you change the polarity then motor will rotate in oppo ...
Hi Guys! Hope you’re well today. Happy to see you around. Today, I’ll walk you through the Introduction to IRF520.The IRF520 is an N-channel power MOSFET mainly used for switching and amplification purposes. It comes with a breakdown voltage of around 100V and a low gate threshold voltage is 4V, making it an ideal pick for microcontroller applications.
I suggest you read this post all the way through as I’ll detail the complete Introduction to IRF520 covering datasheet, pinout, features, and applications.
Let’s get started.
Introduction to IRF520 MOSFET
The IRF520 is an N-channel power MOSFET mainly used for switching and amplification purposes.
It comes with three terminals named: gate, source, and drain and is available in the TO-220 package.
It is important to note t ...
Hey Guys! Hope you are doing well. I always take pleasure to keep you updated with valuable information related to information and technology. Today, I'll discuss the detailed Introduction to ULN2803 which is a relay driver that comes with a high-voltage and high-current Darlington transistor array. In order to obtain higher current capability, the Darlington pairs are connected in a parallel configuration.
The component is incorporated with eight NPN Darlington pairs, featuring high-voltage outputs with common-cathode clamp diodes that are directly related to switching inductive loads. Each Darlington pair features a decent amount of collector-current rating i.e. around 500 mA.
You must have a look at ULN2003 which is almost similar to this IC ...
Hi Guys! Hope you’re well. I welcome you on board. Thank you for viewing this read. In this post today, I’ll walk you through the Introduction to BC557.
BC557 is a bipolar junction transistor with DC current gain 300. It falls under the category of PNP transistors where one N-doped layer stands between the two P-doped layers. The continuous collector current is 100mA means it can drive load under 100mA. BC557 comes in the TO-92 package and is mainly used for switching and amplification purpose.
Before I bore you to tears, let’s dive in and read the complete introduction to BC557 covering datasheet, pinout, working principle, power ratings, physical dimensions, and applications.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I will provide you document on detailed discussion about Introduction to LM224. LM-224 has four internal builtin operational amplifiers. These amplifiers are frequency compensated. The basic purpose to design these type of device is to operate it from a single power supply sources. Moreover, they are also able to perform different tasks using split power supplies. Magnitude of power supply and the current current drain both are independent of each other.
LM-224 has a very wide range of application areas which include DC gain blocks, transducer amplifiers etc. LM 224 has a large number of amazing features include wide power supply ranges, large bandwidth, low input offs ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a new Home Automation Project using XBee & Arduino. Home Automation Project is a most commonly designed project by the engineering students. So, that's why I have thought to create a complete Home Automation Project so that engineering students can get benefit out of it.
We all know about automation which is originated from automate or automatic. In automation the task is done automatically and you don't need to control it. In normal Home automation project, there are few sensors which are displayed wirelessly to user and there are few controls like user can ON or OFF Lights, Fans etc via remote or mobile App.
In this Project, I have used Arduino ...
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 ...
Hey Guys! I hope everyone's fine. Today, we are going to have a look at What is MOSFET? We will cover MOSFET Definition, Full Form, Symbol, Working & Applications in detail.
MOSFETs are commonly used in many electronic applications. A number of MOSFETs are added in tiny memory chips or microprocessors that are widely used in cell phones and laptops. It is a voltage-controlled device that is used for amplification and switching purposes. I'll try to touch every area related to MOSFET. Let's get started.
What is MOSFET?

Hello Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to BD136.
BD136 is a medium power general-purpose transistor mainly used for switching and audio amplification purposes. It belongs to the PNP transistor family and comes with collector current 1.5A, indicating it can drive loads under 1.5A. The amplification factor ranges from 40 to 250, which means it can amplify the input signal up to 250 times. Both collector-emitter and collector-base voltages are 45V while the emitter-base voltage is 5V, indicating only 5V is required to bias this transistor.
