Hello friends, I hope you all are doing well. Today, I am going to share the 4th chapter of Section-III in our Raspberry Pi programming course. In the previous lecture, we studied the Interfacing of IR sensor with Raspberry Pi 4. In this guide, you'll learn how to interface a PIR sensor with Raspberry Pi to create a motion detector. A passive infrared (PIR) sensor is a straightforward yet effective tool for motion detection.
As a bonus, a piezo speaker will play an audio clip whenever motion is detected. GPIO pins are required for both of these accessories. This tutorial is a great starting point for those who have never worked with electronic components and circuits.
These sensors are used in traditional, old-generation security
systems. In con ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide the detailed discussion on PIR Sensor Arduino Interfacing. PIR basically stands for Passive Infrared Sensor. Basically PIR is an electronic equipment which is often used to measure the infrared light radiating from the different objects in their field of view. It detects the infrared energy released from animals as well as from human beings, when this energy is higher than the certain threshold level PIR sensor shows an indication correspondingly. The energy detected by PIR sensor is usually in the form of heat i.e. emitted by humans as well as from animals.
We can also test and verify our results in Proteus using PIR sensor. I have already shared ...
Hello Everyone! Happy to see you around. In this post today, we’ll cover the 2SC2240 NPN Transistor. We will have a look at the 2SC2240 Datasheet, Pinout, Power Ratings, Equivalents & Applications.
Electrons are the majority charge carriers in this NPN transistor, in contrast to PNP transistors, where holes are the majority carriers. The 2SC2240 comes with a power dissipation of 0.3W, the amount of energy this transistor dissipates while operating in the forward-biased state, while the collector current is 0.1A means it can support load up to 0.1A.
This NPN transistor contains 3 terminals, named:EmitterCollectorBase
If the voltage at the base terminal is above 0.7V, the transistor will get forward-biased and the current will start flowing from Collector to Emitter terminal. If the ...

Programmers use different programming languages so that they can create front-end and back-end applications well. One of the people’s main choices is Node.js. This particular programming language allows the creation of applications using JavaScript.
What Exactly is Node.js?

Node.js is usually the choice of programmers because it is open-source. What does this mean? It means that the source code for it is readily available. Contributors from different parts of the world are maintaining the source code.
Node.js cannot be pr ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate you about Introduction to LM1458. Lm 1458 is basically a general purpose dual Operational Amplifier (Op-amp) i.e. it consists of two internal amplifiers. The internal amplifiers has both common power supply as well as common biased network. This is done so that their operation remains dependent on each other.
If the power supply and biasing is not common then they will be totally independent. LM 1458 is a device which is protected from short circuit and it requires no external components for the frequency compensation. LM 1458 is considered to be and ideal amplifier for voltage followers. This is due to its latch-up free operation and high commo ...

Welcome to the second chapter of our beginner's course on the Raspberry Pi. In the previous tutorial, we learned about the components of this little computer. We also considered its uses, as well as the most important advantages and disadvantages. Let's get started with setting up our little computer to run the Raspbian operating system in this lesson.
How to Install Raspbian using an imager
The next step is to make sure you have your board and SD card. The Raspberry Pi has an operating system because it is a full computer. For those who prefer a GUI desktop experience, a headless mode is still an option. Most people use Raspbian, a Debian-based operating system tailored specifically for the Raspberry Pi. However, there are other options. An exce ...

It is good practice to shape your project using breadboards when you are in the initial stages of your project and testing different methods to mee ...
Plastic injection molding involves exposing plastic pellets to extreme temperatures to melt and become malleable. Afterward, manufacturers inject the melted plastic into a mold cavity so that upon cooling, the plastic adopts a specific shape producing the final product.
The versatility of the process makes plastic injection molding a highly beneficial method of producing plastic parts. It's similar to steel forging, finer grains are molded making the final product much stronger. If you decide to go for the plastic injection molding method of creating plastic parts, you will realize the reliability and simplicity that the technique provides. Here are some of the significant benefits of plastic injection molding to consider:
It is highly efficient ...
