Hey Fellas! We always strive to give you useful information that resonates with your needs and requirements. Today, I'm going to unlock the details on the Introduction to 4n25. It is a standard single channel 6 pin optocoupler that contains silicon NPN phototransistor and gallium arsenide infrared LED. It is widely used in motor drive and control, communication and networking, and power management.
I'll try to cover every aspect related to this optocoupler so you don't need to go anywhere else and find all information in one place. Let's dive in and explore what it does and what are its main features.

Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity.
What is ESP-NOW Protocol?
Fig. 1: ESP-NOW Protocol
ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif.
Features of ESP-NOW Protocol:
It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using Wi-Fi.
ESP-NOW protocol does not require a handshake for establishing a connection but, they require pairing and once the devices are paired they can exchang ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to S8550. S8550 is a PNP transistor henceforth during reverse biasing both the collector and emitter will be open and during forward biasing these will be closed. The value of gain is 300 this value governs the magnification ability of the transistor. Its gain is very high therefore it is used for magnification solicitations.
When it is completely biased it can permit a maximum 700mA current to drift crosswise the collector and emitter. This phase is named as Saturation Region and the distinctive voltage permitted across the (VCE) or (VCB) can be 20V and 30V correspondingly. In today’s post, we will have a look at its protection, ...
Hello Guys! I welcome you on board. In this post today, I’ll document the detailed Introduction to 1n4744.
The 1n4744 is a Zener diode that comes with a total power dissipation of 1W. It is used in high-power rating circuits for clipping purposes. This component is composed of silicon material and comes with a forward voltage drop of 1.2V. This Zener diode is a bit different than a regular diode in terms of current conduction. The 1n4744 conducts in both directions i.e. forward-biased and reverse-biased conditions. While the regular diode conducts in forward-biased condition only. Zener diodes are also employed to prevent the electrical circuits from overvoltage.
Read the entire post as I’ll detail the datasheet, pinout, features, and applications of 1n4744. Keep reading.

Hi Everyone! I hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to MID400.The MID400 is an 8-pin optically isolated AC line-to-logic Power Line Monitor Optocoupler. The AC line voltage is detected by two back-to-back LEDs that are connected in series with an external resistor. When this device identifies the AC voltage, the output pin goes low and when there is no AC voltage detected, it remains high.
This feature of detecting the AC line voltage is widely employed in AC to DC control and relay latching applications. I suggest you buckle up as I’ll walk you through the complete introduction to MID400 covering datasheet, pinout, features, equivalents, and applications. Let’s dive right in.

Hello friends, today's post as the name suggests is about how to send SMS with Arduino UNO and SIM900D using AT Commands. There are different types of SIM900D modules available in the market, so it doesn't matter which module you are using. All SIM900D modules work at AT commands basically so today I am going to show you how to send an SMS via AT commands without using any Arduino library. You should first read the AT commands manual which will give you an idea about AT commands. AT commands are special sets of commands which are used for communicating with SIM900 module. Using these AT commands we let our GSM work for us. Like if you want to send SMS then there's a specific AT command for sending the SMS similarly if you want to change the PIN co ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you Arduino 74HC595 Interfacing and we will have a loook at How to Increase Arduino Output Pins with 74HC595. Suppose you are working on some project where you need to control 20 LEDs with Arduino UNO and you know we will 12 digital Pins so we can't control all of these 20 LEDs with Arduino UNO. We can use Arduino Mega as well but if we wanna stick to Arduino UNO then we need to increase its Output Pins and we will use 74HC595 for that purpose.
You should read this basic Introduction to 74HC595, it will help you to better understand this shift register. It's a Serial In Parallel Out Shift register and we will give it value serially from single Pin of Arduino and ...
Hello Learners! welcome from the team of The Engineering Projects. We hope you are having a productive day. We are working on a series of Blogs based upon the core knowledge about Digital Logic Gates and Circuits. In this tutorial, we'll know about the SR Flip Flops and after brief introduction we will simulate SR Flip Flops in Proteus. Let's have a glimpse on the topics of today:
What are Flip Flops?
What are the types of Flip Flop?
How does we design the Truth Table of SR Flip Flops?
What are further classes of SR Flip Flips?
Implementation of SR Flip Flops in Proteus.
Flip Flops
Flip Flops are extremely important Circuits of Digital Logic Design. We Introduce the Flip Flops as:
"Flip Flops are type of sequential Logic Circuit that co ...

Hello friends, hope you all are fine and having fun with your lives. Today's post, as the name suggests, is about Arduino UNO PCB Design in Proteus ARES. I have already posted Arduino Library for Proteus on my blog using which one can quite easily run Arduino simulation in Proteus.but what if you wanna do the Arduino UNO PCB design in Proteus, then you are lucky that you are reading this post. :)
In one of my projects, I have to design the PCB for Arduino in Proteus so I thought to also post it here so that others can download it as well. Normally PCB design is not required for Arduino and I usually get Atmega328 out of Arduino and use it separately but sometimes, depending on the requirements of your project, you may also need to place Arduino it ...
