Hello friends, today's post is about designing a simple calculator with 8051 Microcontroller. In our previous post, we have seen How to Interface keypad with 8051 Microcontroller in Proteus ISIS. Moreover, we have also worked on Interfacing of LCD with 8051 Microcontroller in Proteus ISIS. If you haven't read these two posts then my suggestion is to read them first before going into the details of this post, as we are going to use both keypad and LCD in order to design the simple calculator with 8051 Microcontroller.
Actually we have already understood the working of both keypad and LCD so I thought to share this small project as it will give you the practical application of both keypad and LCD. And if you are new to 8051 Microcontroller then its ...
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.

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to BC337.
BC337 is a general-purpose transistor mainly used for lower power audio amplification and switching purposes. It belongs to the NPN transistor family and comes with a maximum gain of 630. The continuous collector current is 800mA indicating it can drive loads under 800mA.
I’ll be discussing the complete introduction to BC337 in this post covering pinout, working, power ratings, alternatives, applications, and physical dimensions of BC337.
Stay tuned.

Hi Friends! I hope you are doing well. Welcome you onboard. Today, I'll discuss the basic Introduction to HC-SR04 Ultrasonic Sensor. It is an ultrasonic sensor, also known as an ultrasonic transducer that is based on a transmitter and receiver and mainly used to determine the distance from the target object.
The amount of time it takes to send and receive waves will determine how far the object is placed from the sensor. It mainly depends on the sound waves working on “non-contact” technology. The required distance of the target object is measured without any damage, giving you accurate and precise details.
This sensor comes with a range between 2cm to 400cm and is used in a wide range of applications including speed and direction measurement, wireless charging, humidifiers, medical ...
In the previous post we have seen the project description of Voice Recognition Project using EasyVR shield. Today we will have a look at Getting started with EasyVR commander. EasyVR shield is a module which is used for voice recognition. First of all, we save our commands in the EasyVR shield and then we use these commands to control anything. In this project, I need to control the robot with voice commands like when someone says FORWARD then the robot start moving in forward direction.
Now first of all what I need to do is to save this FORWARD voice in the shield, which we will see today how to save the command in the shield and after that I will show you the Interfacing of EasyVR shield with Arduino UNO. So that when I say Forward the motor sta ...
Hello Friends! Hope you are doing great. I am back to give you a daily dose of valuable information so you can excel and grow in your relevant field and keep coming back for what we have to offer. Today, I am going to unlock the details on the Introduction to 8051 Microcontroller. This is an 8-bit Microcontroller developed by Intel in the 1980s. It is considered as a small system on an integrated chip that comes with CPU, I/O ports, timers, counters, RAM and ROM. The Microcontroller is a one step forward to a microprocessor.
Both Microcontrollers and microprocessor work in a similar way with some exceptions. Microcottler comes with everything required to run an embedded system like CPU, I/O ports and inbuilt peripherals like timers, counters, ...
Hi Guys! Happy to see you here. Thank you for viewing this read. In this post today, I’ll walk you through the complete Introduction to BC550. BC550 is a low-power low-frequency general-purpose bipolar transistor. It is mainly used to drive loads under 100mA. BC550 carries three terminals where a small current across one terminal is used to control the large current across the remaining terminals. It’s primarily used for amplification and switching purposes. Transistors are critical components and building blocks of modern electronic circuits. Bipolar junction transistors are divided into two main types named NPN transistors and PNP transistors. The BC550 falls under the category of NPN transistors and is available in a plastic TO-92 case. I sugge ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share a new IR Proximity Sensor Library for Proteus. Proximity Sensors are not available in Proteus and we are sharing its Proteus library for the first time. So far, I have only shared Proteus Libraries of digital sensors but today I am sharing an analog sensor, so too excited about it.
In the next few days, I will keep on sharing Proteus Libraries of different analog sensors, so if you want any sensor in Proteus, then let me know in the comments. IR Proximity Sensors are used to detect hurdles/obstacles placed in their path. They are normally used on robots for path navigation and obstacle avoidance. So, let's have a look at How to download and simulate IR Proximit ...
Hello friends, hope you all are fine and having fun with your lives. In today's post we will have a look at How to interface keypad with Arduino in Proteus ISIS. Keypad is used almost in every engineering project. If you even look around you will find keypad in many electronic appliances. For example, a simple ATM machine has a keypad on it using which enter our pin code and give commands to the ATM machine. Similarly, calculator also has keypad on it. So, in short there are numerous applications of keypad. You should also read the Real Life examples of Embedded Systems and you will find Keypad in them as well.
Keypad is used where you need to used numerical buttons or you need to use lots of buttons for sending commands so like in some applicatio ...
Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll describe the Introduction to 74LS74.
74LS74A flip-flop IC carries the Schottky TTL circuitry to generate high-speed D-type flip-flops. Every flip-flop in this chip comes with individual inputs, and also complementary Q and Q`(bar) outputs.
Flip-Flops are normally considered as the basic building blocks of modern digital electronics. These flip-flops are used to store the binary data where stored data can be varied by applying the different inputs.
I suggest you buckle up as in this post I’ll walk you through the complete introduction to 74LS74 covering datasheet, pinout, features, and applications.
Let’s get started.
