Hi Folks! Hope this finds you well. Thank you for stopping by. In this post today, I'll be discussing the Introduction to BD137.
BD137 is an NPN medium power transistor mainly employed in switching and audio amplification applications. It is composed of silicon material and comes in the TO-126 package. The collector-base and collector-emitter voltages are 45V and the emitter-base voltage is 5V which details that only 5V is required to bias this transistor and start transistor action. The collector current is 1.5A which documents that it can support loads under 1.5A. Power dissipation is 12.5W and storage temperature ranges from -55 to 150C.

The usage of 3D printing has received a lot of attention, but what exactly is FDM 3D printing or FFF 3D printing? FDM 3D printing is used in a variety of sectors. Automobiles and a broad range of consumer products makers are among the industries. They use FDM to aid with product design, prototyping, and manufacturing. Some product companies employ FDM 3D printing since the thermoplastic utilized during creation is ideal for children's toys to sports gear.
Gifting
FDM, as previously said, is among the most democratized 3D printing services, enabling hobbyists and amateurs to produce new goods quickly. They can quickly develop, iterate, revise, and print parts that meet their specifications.
The gifting business is also adopting 3D printing technology to make present products, riding the w ...
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 friends! I hope you are doing well. Today, I will give you a detailed overview of the Electrocardiogram, abbreviated as ECG or EKG. An electrocardiogram is a biological test used to convert the activities of the heart into electrical signals, and these signals are then read by specialized surgeons to predict heart conditions. In simple words, ECG is used to record the rhythm of the heart activity on a moving strip of paper. Related doctors are able to read the spikes and dips on the paper and can decide, whether the heart is in normal condition or not. These spikes or dips are usually known as waves.
As we know, the heart is a muscular pump consisting of 4 chambers. There are two lower chambers and two upper chambers. Lower chambers are know ...
Hello friends, I hope you are happy, healthy and content. We have been discussing embedded systems lately and this discussion would be incomplete without an in-depth discussion on Real time embedded systems. You might have observed their utility and their absolute need in our constantly changing external and internal environment, the ease of managing the room temperature with a single tap, generating several results with a single click and streaming videos and playing games anytime and anywhere are the blessings of real time embedded systems.
Definition of Real Time Embedded Systems
Real time embedded systems can be defined as;
"The embedded systems which respond to real time situation with the help o ...
Hello! welcome to The Engineering Projects. Are you a business owner? A content creator? A college student looking for a place of free expression? Then do not worry! All you need to take your ambitions to the next level is a new website to establish a substantial internet presence from the first day of your new adventure.
Having a website is an excellent way to increase community engagement and have a platform that exists solely for your work to be visible to the general audience. However, if you’ve been thinking and going around the internet to look for a procedure, there’s a strong
chance that you’re feeling overwhelmed right now.
Complicated words like web hosting and choosing a domain name scare away a newcomer. Hence, we’re here to help you ...
Hello everyone, I hope you all are doing great. In today's tutorial, I am going to give you a detailed Introduction to Arduino YUN, and we will also have a look at its basic functionalities. Arduino YUN is a latest microcontroller board, manufactured by Arduino. It's the most advanced and highly stylish arduino board. The beauty of Arduino YUN lies in having two on board processors, which I haven't seen yet in any other Microcontroller board. One of them is simple Arduino processor which is similar to that of Arduino Leonardo while the second processor is Atheros AR9331. Atheros supports Linux server, which is the new thing in Arduino YUN. Because of these two processors, one now can do anything in the world of automation as well as web servers. ...
Hello, fellows, I hope you all are doing great. In today’s tutorial, we will discuss Three Types of Banners to Maximize Brand Awareness. The goal of all forms of advertising is one simple thing - to “wow” your prospective customers and other business associates. Banners help you achieve this oomph factor, provided you make the right choice of format, design and printing.
Selecting the most appropriate format and creating visually appealing designs don’t need to cost a bomb, say experts at Print Banners, a company that provides high-quality design and same day banner printing in NYC. What’s important is to make informed decisions. So, let's get started with Three Types of Banners to Maximize Brand Awareness.
Three Types of Banners to Maximize Brand ...
Hello friends, I hope you all are doing great. Today, we are going to start a new section in our Raspberry Pi Programming Course. In this section-VIII, we will implement advance protocols in the RPi4 board. Today's our first lecture in this section and we are going to interface a USB Bar Code Scanner with Raspberry Pi 4.If you have visited any big grocery store, you must have seen, it's
quite important as well as difficult to maintain the products in stock
at all times. To ease the job, barcode technology is used because it can
easily maintain an organized database of your items, costs, and
inventory levels in one convenient location. Price changes can be
implemented whenever you desire without requiring new labels for
previously packaged goods. You can tell exactly when your s ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to interface the PIR sensor to detect motion with the Raspberry Pi Pico module and MicroPython programming language. Later in this tutorial, we will also discuss the interrupts and how to generate an external interrupt with a PIR sensor.
Before interfacing and programming, the PIR and Pico boards let’s first have a look at the quick introduction to the PIR sensor and its working.

PIR motion sensor and its working
PIR stands for Passive Infrared sensors and the PIR module we are using is HC-SR501. As the name suggests the PIR or passive infrared sensor, produces TTL (transistor transistor logic) output (that is either HIGHT o ...
