Hello everyone, hope you all are fine and having fun with your lives. Today's tutorial is quite simple and we will have a look at circuit diagram of IR sensor using 555 Timer. There are different types of IR sensors available in the market. IR is abbreviation of infrared and so they use infrared ray for detection of objects. There are many types of IR sensors with different functionality, but in all of them infrared rays are omitted from transmitter and are received by the receiver. and using these ray we can say whether an object is placed in the path or not.
Today we are gonna see how to design your own IR sensor using 555 Timer. We can also interface these IR sensors quite easily with any microcontroller like PIC Microcontroller , Arduino etc. ...
Hey Guys! I hope you all are doing great. In the previous tutorial, we studied the basics of Semiconductors, where we briefly discussed the PN Junction. Today, we are going to have a detailed overview of PN Junction.
But before getting into the details of PN Junction, we need to first recall a few concepts from the previous lecture:
Semiconductor Basics
As we know, the conductive power of a semiconductor material lies between a conductor and an insulator. So, it can act as a pure conductor as well as a pure insulator, depending on the applied conditions. Semiconductors are divided into two types:
Intrinsic Semiconductor.
Extrinsic Semiconductor.
Intrinsic Semiconductor
A semiconductor in its pure form is called an Intrinsic semiconductor. In this state, the outermost valan ...
It is so convenient to store data in the cloud, most people do the same. It is accessible. It is easier. And there are a lot of benefits cloud computing offers. It stores information on the cloud rather than the local servers, making it cost-effective.
With that, the use of Big Data is getting popular each day. The data sets are huge and complex in volume, speed, and variations. All these links give adequate performance, all-time accessibility of resources, swift implementation, and cost-efficiency.
The whooping utilization of the tech also increases the risk and doubts about data security. With the growing prevalence of cloud computing and its remarkable ability to improve your activities' reach and efficiency, it is a big win.
In 2023, a study forecasted that cybercriminals will ...
Hi Fellas! I hope you all are having fun. Today, we will have a detailed overview of Flexible PCB. We will also understand why we need to use Flex PCB? What are its advantages & disadvantage? What kind of material is used? and How to manufacture flexible PCB? etc. Flexible PCB is the most advanced type of PCB, thus quite expensive and is normally used in industrial electronic products.
I'll try to explain everything related to flexible PCB so that you could get a clear idea of what is this about and what makes it stand out from other PCB boards? Let's dive in and explore the properties of flexible PCB one by one:
What is Flexible PCB?
Initially, PCBs were designed using hard substrate materials and th ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to C1815. The C1815 is a transistor like other it is used to amplify acoustic frequency signal. Most transistors are coded for easy documentation through these titles can differ by builders. One or two erudition are typically trailed by a sequence of statistics, and then probably additional statistics. Consequently, a C1815 transistor can also be recognized as a 2SC1815 transistor.
It is used as a switch to initiative loads below 150mA. The use of transistors aided the electronics manufacturing alteration quickly, and developments in expertise are permitting minor apparatuses to be used to production of slighter expedients. In toda ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of you about how to make a simple program for DC Motor Direction Control using Arduino. The word DC is basically an abbreviation of Direct current. So, a direct current motor is commonly used motor having two input terminals, one is positive and the other one is negative. If we connect these terminals with the voltage supply the motor will rotate. If you change the polarity then motor will rotate in opposite direction. You should also have a look at Difference between DC & AC Motors to get a better idea about these motors.
DC motor has a lot of applications. You can use it in automation projects, for controlling static as wel ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is KCL ( Kirchhoff's Current Law ). KCL (Kirchhoff's Current Law) is the fundamental rule of electric circuitries. In 1845 a German physicist Gustav Robert Kirchhoff presented two essentials rules to explain different circuitries. Ist law is KVL (Kirchhoff's Voltage Law) and 2nd is KCL (Kirchhoff's Current Law). These rules further defined the working of Georg Ohm, who gave Ohm’s Law and lead the work of James Maxwell who gave Maxwell equation.
Both of these rules also work for a time (t) and frequency (f) measurements. In certain cases when the frequency of a signal is higher these laws work for the alternating current circuitries. In today’s post, we will ha ...
Hey pupils, Welcome to another lecture of this series on signals and systems, and this is the time to learn an interesting topic in which you are going to learn about the convolution of the signals. In the previous sessions, we have learned basic operations on the signals, and this time, you are going to know the convolution of the signals and different criteria that are related to this topic. Have a quick view of the concepts that will be clarified in this lecture: What is convolution? What are some basic types of convolution? How can you define the properties of linear convolution? How can you implement convolution in MATLAB using function and without function? What is the difference between linear and circular convolution? What is the convolution of signals? Convolution is ...
A lot of people took engineering for the love of math and machines. Most are introverts as well, diligently doing their project in workshops, plants, or computers. Unless you are in sales, academia, or managerial positions, you don’t meet a lot of people as much as a doctor or a lawyer.
However, this should not stop you from establishing your network. People networks may not be the most popular engineering tool. Albeit, you might be surprised by how useful and powerful it can be.
The good thing is that there are contact management apps nowadays. You can compartmentalize your contacts- suppliers, specialists, laborers, and so on. With the
right contact management app
, you can reap the following benefits.
