Hello friends, I hope you all are doing great. Today, we are going to start Section-III of our Raspberry Pi 4 Programming Course. In this section, we will interface different Embedded Sensors with Raspberry Pi 4. Today's our first lecture in Section-III, so I am going to interface a simple LDR sensor with RPi4.
So, let's get started:
Components Required:
The following items are required to finish this Raspberry Pi

this, but having one would be helpful.Raspberry pi 4BreadboardPhotoresistor LDRJumper wires1uF Capacitor
What is a photoresist?
It is a common practice to employ photoresistors to determine the presence or absence of visible light or to quantify the amount of ...
Hello people, I hope you all are having a great time. Let us start our discussion with a simple question, how you keep a track of your progress be it daily, monthly, or yearly? Or how your professor for fluid dynamics or any other course keep you on your toes throughout the semester? Definitely by keeping a proper schedule and record or maybe by tracking your progress through an app or anything manual!
Have you ever thought about how big companies keep themselves on track? How they manage a huge network of employees by keeping in check their progress individually? Or how the day-to-day or hourly tasks are assigned and kept under check daily for every employee of the company? All these things are done through workforce management. Today, we will be ...
Hello students! Welcome to the new Python tutorial, where we are learning a lot about this programming language by applying the codes in a Jupyter notebook. It is interesting to see how simple codes with easy syntax can be useful to store, retrieve, and use data in different ways. Many things in Python are so unadorned and pre-defined that programmers may use them in a productive way without any issue.
In the previous lecture, we have seen the details of the sets and how different types of mathematical operations are used to get the required results. We have seen many codes, the examples of which were taken from day-to-day life. In the present lecture, the mission is to learn a new topic that is related to the concepts of previous lectures. Yet, it is important to have a glance at t ...
Greetings! This is the complete project of our Raspberry Pi 4 tutorials. In our previous tutorial, we learned to set up our raspberry pi as a virtual private network server. In this tutorial, we will design a smart attendance system using an RFID card reader, which we will use to sign in students in attendance in a class.
First, we will design a database for our website, then we will design the RFID circuit for scanning the student cards and displaying present students on the webpage, and finally, we will design the website that we will use to display the attendees of a class.
Components
RFID card kit
Breadboard
Jumper wires
Raspberry pi 4
I2C LCD screen
Design a database in MySQL server
Additionally, the Database server offers a DBMS ...
Hello, everyone, I hope you are doing great. In this tutorial, I am going to explain you about C# checkbox control, in my previous tutorials I have already explain you, C# RadioButton Control, C# ListBox Control, C# Button Control and C# Checked ListBox Control. C Sharp checkboxes have their own values in point of sale mission and desktop application development. Checkboxes are basically used to retrieve the specific data from the user.
C# CheckBox allows the user to give specific input. It's mostly used where we have to retrieve the specific data from the user such as the gender selection, terms and condition agreement, and age-restricted data. You can simply use a single object C# CheckBox or multiple objects it totally depends on your requireme ...
Starting your own YouTube channel or making home movies is very exciting. However, finding the right video editing software can feel like a big challenge. Most professional video editing tools are way too hard for a normal person. Amidst all the search, you need a simple video editor that helps you get your work done.
Filmora is a great choice for people who want editing without effort. So, this guide shows how this video editor makes your creative editing work better.
Part 1. Video Editor Overview: Why Filmora is Ideal for Beginners
Most professional video editing software has too many buttons, which can be confusing. Below is the main overview of why Filmora is the best for your start.
What is Filmora, and Who Should Use It
Filmora is a powerful tool used to edit high-quality videos ...
Hey Guys! Glad to see you here. I welcome you on board. In this tutorial today, I’m going to share the Analog PIR Sensor Library for Proteus. We have already shared the digital PIR Sensor Library for Proteus V1.0. Moreover, you should also check the latest version of PIR Sensor Library V3.0. If you don’t know what is PIR sensor, you must read this post first where I’ve briefly discussed the Interfacing of PIR sensor with Arduino.
PIR (Passive Infrared Sensor) also known as a motion sensor, is used to detect motion using infrared rays. It is used in banks for security purposes. It can detect the presence of a person by identifying their motion inside. Similarly, it is used in home automation where it detects the movement in the room, giving a signal we need to turn on the light because ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give a detailed discussion on Introduction to LF411. LF-411 is a Junction Field Effect Transistor (JFET) input Operational Amplifier (Op-amp). It is the most common module available in the market these days due to its cost efficiency. LF 411 has low input offset voltage. Input offset voltage drift is guaranteed for LF-411. A very low supply current is needed for this device. It provides higher slew rates as well as high gain bandwidth product.
Moreover, LF411 also provides lower input bias current as well as lower input offset currents. It is an 8 pin operational amplifier. The details about its pins will be discussed later. Due to its low cost and high ...
Hi readers! Hopefully, you are well and exploring technology daily. Today, the topic of our discourse is the AHT10 high-precision digital temperature and humidity measurement module. You might already know about it or something new and different.
The AHT10 high-precision digital temperature and humidity measurement module is the latest environmental sensing solution tailored for modern applications. Designed using cutting-edge technology, this unit can ensure accurate, stable, and reliable measurements for temperature and humidity.

Hello students, I hope this tutorial finds you happy, healthy, and content. The topic we have at hand today is "3D printing", it is a very interesting and versatile topic, and extremely easy to comprehend as well, it would definitely keep you hooked to your screens. You might have heard a lot about 2D and 3D objects, in this digital era almost everyone has at least once heard of it, do you know what is a 3D object?
A 3D object can be defined as,
"An object or structure that has three dimensions which includes width, length, and height."
Definition of 3D Printing
As you are now familiar with the term 3D we shall proceed further with our actual topic, so
Here we have the most commonly asked question of all, what is 3D printing?
3D printing can be d ...
