Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation. If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons.
First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.).
Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly).
Because of these two reasons, we have to use the driver in between t ...
Hey Fellas! I hope you are doing great and having fun. We love when you keep coming back again and again for what we have to offer that resonates with your needs and requirements. I am back to give you a daily dose of useful information so you can excel and grow in your relevant field without much effort. Today, I am going to unlock the details on the Introduction to 2n4400. It is an NPN (negative-positive-negative) bipolar transistor which is mainly designed for general purpose amplification and switching applications. I'll cover each and everything related to this transistor, so you get all information in one place without roaming around on the internet. Let's get started.

Hi Geeks, welcome to our new project. Our new project is one of the most common issues you’ve seen in your cities. In this project, we are going to make a car parking system with automatic billing. In the entire world, there are an estimated 1.4 billion cars on the road, which is absolutely great news if we are considering the development of the Automobile industry. But the most serious issue is that the number of cars exceeds the number of available parking places, resulting in traffic congestion. Damaged cars due to this lack of space, fewer parking locations, lack of parking signage, informal parking, and overcharging for parking are just a few of the issues.
People are still choosing manual parking methods, which have a number of drawbacks, suc ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate about the Introduction to LM324. It is an Operational Amplifier (Op-amp) consists of four channels. Its a low cost device having true differential inputs.For single supply applications LM 324 are superior to the other operational amplifiers. LM-324 is capable of operating at the minimum voltage up to 3V and at the high voltage levels up to 32V.
One of the major advantage of LM-324 is that common mode input range includes negative supply which eliminates the need of external biasing. Negative power supply voltage is also included in output voltage range. This device is lead (Pb) free, halogen free and RoHS compliant. It consists of four amplifier ...
Hi Guys! Hope you are doing well. I am back to give you nuggets of valuable information related to engineering and technology so you can excel and grow in your relevant field. Today, I'll unlock the detailed Introduction to 1n4738a. It is a zener diode that comes with high power rating and is mainly used in stabilizing and clipping circuits.
The zener diode is slightly different from regular diode as former can conduct in both directions while later conducts in one direction only. It is available in double slug construction with corrosion resistant surfaces, helping to operate it under high temperature and pressure.
I'll try to cover each and everything related to this diode, so you don't have to grapple your mind surfing the whole internet and ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send an email using ESP32 module. We will also learn to send text files, images or some sensor readings using the SMTP server using the ESP32 module.
In IoT (Internet of things), there are various applications where we need to send emails carrying information like sending some sensor readings, altering emails, images, text files and much more.
What is SMTP?
SMTP or simple mail transfer protocol is an internet standard for sending and receiving electronic mail (or email) where an SMTP server receives emails from the email client.
SMTP is also used for setting communication between servers.
Various email providers like Gmail, Hotmail, Yahoo, etc. have unique SMTP ...
Hello friends, hope you all are fine and having fun with your lives. In today's post, I am gonna share How to get Hex File from Arduino. It's quite a simple post and I have already explained it many times in my posts but still, I am getting a lot of messages regarding it that's why I thought to write a separate post for it. First of all, let's have a little introduction about it. If you have worked on PIC Microcontrollers or Atmel etc then you have seen that you always get hex files from their compilers and then you burn that hex file in the respective Microcontroller using their programmer or burner. But that's not the case with Arduino. In Arduino boards, you simply plug it with your computer and you hit the Upload button and the code automatica ...
Hey Guys! Hope you are getting along with life pretty well. Welcome you onboard. Today, I'll unlock the details on the Introduction to Arduino Micro. It is a Micro board, based on the ATmega32U4 microcontroller and comes with built-in USB, making it easily compatible with the computer.
Arduino Micro, as the name suggests, is the smallest board in the Arduino Community. It is comparable to its counterparts like Arduino Nano and Arduino Promini.
In this tutorial, I'll discuss each and everything related to Micro board including its main features, pinout, pin description, the software used and applications. Let's dive in and explore everything you need to know about this tiny board.

Update: We have created a new version of this library, which you can check here: Arduino Mega 2560 Library for Proteus V2.0.
Hello friends, hope you all are fine. In today's post, I am going to share Arduino Mega 2560 Library for Proteus. In the previous post, I have shared the Arduino UNO Library for Proteus and I have mentioned that I am gonna share more Arduino Libraries soon. Actually these days I am quite excited about this Proteus component designing and I am designing the Arduino boards as a starter. So, till now I have designed two Arduino boards in Proteus. First one was Arduino UNO which I have provided for download in previous post and today, I am going to share Arduino Mega 2560 Library for Proteus.
In the coming posts, I am gonna sh ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 2N3906. It is most common Positive Negative Positive (PNP) Bipolar Junction Transistor (BJT) available in the market now a days.
2N 3906 is specially designed for low power amplification purposes as well as for switching purposes. 2N 3906 is designed for low current, power and for medium voltages. It is capable of operating at moderately high speeds. The range of its collector current is form 10uA to 100mA. Further detail about 2N-3906 will be given later in this tutorial.
