Welcome to the next tutorial of our raspberry pi 4 programming course. The last guide covered connecting a Sharp infrared distance measurement sensor to a Raspberry Pi 4. Infrared (IR) sensors were demonstrated to be widely used for nearby object recognition and motion tracking. But in this session, we'll utilize Raspberry Pi 4 to create a radio-frequency (RF) remote control that can be used to operate the gadgets wirelessly. With the help of this RF remote control, we can Power On/Off the devices.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate you about Introduction to TL081. TL 081 is basically a high speed Junction Field Effect Transistor (JFET) input Operational Amplifier (Op-amp). This Integrated Circuit consists of a JFET with a high voltage and bipolar transistor.
TL-081 provides low input voltage, high slew rates, low input offset current and low Offset Voltage Temperature Coefficient (OVTC). TL 081 has different features e.g. low power consumption, high input impedance, latch-up free operation, short circuit protection, wide common mode input voltage ranges, wide differential input voltage ranges etc. TL-081 can be used in white good, tablets, computers, personal electronics e ...
Hello friends, today I am posting a very basic tutorial on what is Arduino ??? In this tutorial I am gonna explain the basics of Arduino for the beginners. I am writing this tutorial because I got a lot of requests from the engineers in which they ask questions like what is Arduino ? What's the difference between Arduino and PIC? How to use Arduino? etc etc. So I thought of writing this topic. It's a very basic tutorial so if you are already familiar with this board and know the answer of this simple question What is Arduino ??? then you can skip this tutorial but again you must read it once, may be you get something out of it. :)
I have posted a tutorial on Arduino Projects, in which I gave all the links of Arduino projects and tutorials posted o ...
Introduction
Welcome to the next tutorial in our raspberry pi programming. In the previous tutorial, we learned how we could run Xbox cloud on our pi 4. We found that we can run any game easily without lag or having raspberry pi shut down, proving that pi 4 is quite a powerful minicomputer. However, this tutorial will demonstrate how to use Python on raspberry to monitor websites. This Python program will execute on Pi 4 and watch over a website, alerting you whenever it changes or goes down. This is accomplished by keeping a straightforward webpage duplicate locally and monitoring for updates. This webpage monitor is straightforward, so it should work well on pi Zero. Throughout this tutorial, we will demonstrate how to develop your custom code to monitor a webpage. With this information ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to Create a New View in ASP.NET MVC. It's 7th tutorial in ASP.NET MVC series and I am hoping you are learning from it. If you have any suggestions, then ask in comments and we will help you out.
In our previous tutorial, we have seen How to Create a New Controller in ASP.NET MVC and we have also created the New Model in ASP.NET MVC , so now we are only left with View which we are gonna create today. Both Controller and Model comes under back-end / server side programming while view comes under front-end / client side programming. Here we are gonna create a View for the user to interact. So, let's get started with How to Create a New View in ASP.NET ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at Industries impacted by Virtual Reality. Since its introduction to the mainstream a few years ago, VR technology has been raising excitement in anyone interested in fresh ideas. This concept might not be developing on the level we expected from the beginning. However, the potential of Virtual Reality shows great promise for some fantastic things we could be doing in the future, but even now there are many fields and industries where VR is becoming a real game-changer.
Architecture and engineering
There is a lot that VR-based tools can do for engineers, architects, planners, designers, constructors, and so on. It helps them deliver value and make their work eas ...
Hello friends, I hope you all are well and doing great in your lives. In today's tutorial, I am going to share the Introduction to Inverters. An inverter converts DC voltage or current to AC voltage or current. You can also say that it transfers or converts power from a DC source to an AC load. The aim of this circuit is to supply AC power similar to the one that we receive at homes.
Firstly, I am going to share some basic information related to inverters. In the second section, I will give you the basic configuration or parts of it and in the last section, I will tell you the types and applications. Let's now get started with the Introduction to Inverters:
Introduction to Inverters
An inverter is connected to a DC source and it converts it in ...
Update: I have updated the code and removed the bug. Thanks for informing. Now this code will work perfectly.

Hello friends, hope you all are fine and having good health. Today, as the name suggests, I am gonna post on how to Receive SMS with AT Commands using Sim900 and Arduino. I have already posted a tutorial on How to Send SMS with Arduino UNO and Sim900, so now we are gonna check the opposite. Sending SMS is quite easy, you just need to write some AT commands and write the message you wanna send and hit the Cntrl + Z and it will be sent. But receiving a text message on your SIM900 shield is a bit difficult because now you need to place a check when user will send a message. So, ideally whenever anyone send a message to yo ...
Hello friends, hope you all are having fun in your life.
Today's tutorial is about the component designing in Proteus ISIS. This tutorial actually deals with the presentation of your project. Usually when students give presentation of their projects, then it is asked that add the circuit diagram of their project. Now when students open Proteus in order to design their circuit, they found out that the components they have used in their project are not available in the Proteus Directory. Now what to do ?
In that case, there's a need to design your own component in Proteus and place it in the circuit. Although, this new designed component won't work as the real co ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ATmega328. ATmega328 is an Advanced Virtual RISC (AVR) microcontroller. It supports 8-bit data processing. ATmega-328 has 32KB internal flash memory.
ATmega328 has 1KB Electrically Erasable Programmable Read-Only Memory (EEPROM). This property shows if the electric supply supplied to the micro-controller is removed, even then it can store the data and can provide results after providing it with the electric supply. Moreover, ATmega-328 has 2KB Static Random Access Memory (SRAM). Other characteristics will be explained later. ATmega 328 has several different features which make it the most popular device in today's market. ...
