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 ...

It is made up of silicon. It is basically a power transistor. Power transistor is an electronic device which is able to handle certain level of power. 2SC-3320 has three terminals whose detail will be given later. Its an efficient device with higher efficiency available at at lower cost in the market these days. Due to cost efficiency and its unique features it is more popular devic ...
Hi Everyone! How are you doing, my friends? Today I bring a crucial topic for PLC programmers, technicians and engineers. We have been working together for a long time using ladder logic programming. We have completed together dozens of projects from real life and industry. One day I was thinking about what we have done in this series of ladder logic programming, and I came across that I missed talking about one essential topic ever. You know what? It’s the PLC troubleshooting and online debugging! After writing a ladder logic program for the project, you can imagine it should operate from the download moment 24/7. As usual, any system goes faulty one day. So we need to go through this matter, showing you how to find our PLC faults, troubleshoot, and go online with the PLC to figure out th ...
Hello friends! I hope you will be absolutely fine and having fun. Today, I will give you an elaboration on Introduction to SG3524. I have already shared articles on Introduction to 74HC245, 74HC595, CD4051, L293D, L298, LF351 and LF411. You should also go through all of these tutorials in order to have a better understanding. SG 3524 consists of all the important functions necessary to design inverters.
Moreover, using SG-3524 we can also design regulation power supplies as well as switching regulators. This all design is based on a single chip. High power applications can also be controlled through this device. SG-3524 is especially designed for voltage doublers without transformers, transformer coupled DC to DC converters. Their design was als ...
Hi Friends! Hope you’re well today. I welcome you on board. Today, I’ll walk you through the Introduction to INA219.The INA219 is a current sensor module that incorporates the I2C protocol for submitting the data obtained through sensing current, voltage, and power. It is a bi-directional zero drift current/ power sensing module mainly used in digital multimeters and power profilers.
I suggest you read this post all the way through as I’ll detail the complete Introduction to INA219 covering datasheet, pinout, features, and applications.
Let’s get started.
Introduction to INA219
INA219 is a current/power sensor module mainly employed to sense the power, voltage or current where up to 128 samples can be averaged together to get filtering in noisy environments. This data is then s ...
Hello Friends, I hope you all are fine and will be doing well in your life. In today's tutorial, I am going to give you a detailed Introduction to DHT11. It is an embedded sensor used to measure temperature & humidity in the surroundings and gives calibrated digital output. It can measure temperature in the range of 0°C to 50°C with ±2°C accuracy. Its humidity range is from 20% to 80% with ±5% accuracy. It is a small, low cost and easy-to-interface embedded sensor.
In this tutorial, I will explain its working, pinout, protocol and interfacing with other microcontrollers in detail.
Here are a few important features of DHT11, given in the below table:

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.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explore my knowledge about Introduction to LM317. It is basically a positive voltage regulator having three terminals. It can a supply a current more than 1.5A and voltage in a range of 1.25V to around 37V. You should also have a look at this LM 317 Calculator.
For the adjustment of output voltage only two external resistors are required. It has improved standards of line regulation as well as load regulation. Full overload protection e.g. current limiting, area protection can be achieved using LM317. If its adjusting terminal is disconnected, even then all of the protection circuits will work properly. We can also use LM317 as precision current regulator ...

Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Interface Arduino with 74HC595 & 74HC165. I have already interfaced these shift registers separately with Arduino. In the first tutorial we have seen Arduino 74HC595 Interfacing in which I have discussed How to increase the output pins of Arduino using 74HC595. After that in second tutorial we have seen Arduino 74HC165 Interfacing where we have increased the input pins of Arduino.
So, now we are gonna interface both of these shift registers with Arduino UNO and will increase both input and output pins of Arduino. I have also given the Proteus simulations for download at the end of this tutorial along with Arduino code. So, lets get started with In ...
