Hello everyone and welcome to this article which will be a great introduction to high-speed PCB design. For sure it is going to be a very interesting class. Let me start by posing a question; Is this something that you have ever come across in your world of PCB design? Where you spent too much time doing the schematics, selecting the right components, doing the footprint addition, generating the netlists, doing the proper layout and routing and sending the end product of your design to the manufacturer? At this level you might probably be designing standard types of PCB boards and if someone was to introduce a project that talks about signal integrity, reflections or even crosstalk, very much believe you will feel like a lost person. It might be something new to you. The reason is that suc ...
Selling an app to a buyer requires a careful approach to extract the most value from the digital asset. The marketplace for apps extends well beyond the iOS and Android market to ones for e-commerce platforms, Amazon’s Alexa, Salesforce, and many other places. If you’re thinking ahead about the long-term prospect of selling your app that’s now in development or wanting to exit in the next year, these 5 tips for selling an app are for you. Can You Sell The App? You might believe it is time to cash out your app, but there could be a few problems in your immediate future. Apps developed for the Apple ecosystem can’t always be transferred from one developer to another. It is a good idea to check the latest criteria on app transfers before you look at selling your app. While developers can tran ...
Hello friends and welcome to this article. Today we are going to have a look at the introduction to the ceramic printed circuit boards. we have previously introduced what a printed circuit board is and we noticed that it is a very important part that makes electronic circuits complete and well organized. Having that in mind, we had also discussed several materials that build up these PCBs and today our focus is on the ceramic types of PCBs. Introduction to Ceramic Printed Circuit Board This printed circuit board is referred to as ceramic PCB because of the substrate used in the construction of this board is made up of ceramic and it finds applications in special areas. The process of making this board is that copper is pasted on the surface that is made up of alumina ceramic which is the s ...
Hello friends. In this lecture, we are going to have a look at the different kinds of MATLAB data types. As we have already seen in previous lectures, MATLAB stands for MATrix LABoratory and allows us to store numbers in the form of matrices. Elements of a matrix are entered row-wise, and consecutive row elements can be separated by a space or a comma, while the rows themselves are separated by semicolons. The entire matrix is supposed to be inside square brackets. Note: round brackets are used for input of an argument to a function. A = [1,2,3; 4,5,6; 7,8,9]; An individual element of a matrix can also be called using ‘indexing’ or ‘subscripting’. For example, A(1,2) refers to the element in the first row and second column. A larger matrix can also be cropped into a smaller matrix, as we c ...
Hello geeks, welcome to our new project. We are going to make an important project which will be very useful for us in our daily life which is a variable DC power supply. As engineers who work with electronics need different voltage ranges of DC power supply for different electronic projects and components. It becomes very clumsy and hard to manage different power supplies because of wires which are connected to it and each power supply consumes an extra power socket as well. So in this project, we will overcome this issue and learn to make an adjustable DC power supply, in which we will get a wide range of voltages. Software to install We will make this project in the simulation, as it is a good practice to make any project in the simulation first so that if we do any mistakes or errors i ...
Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer . We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tutori ...
Hello Geeks, I hope you all are doing great and enjoying your festive seasons. This time, we have come up with a new project which will make your festival a bit brighter so here comes a Christmas tree. It is said that Christmas is the center of all the celebrations. Did you guys know the scientist who discovered the light bulb, Thomas Edison and his friends were the first to put up the light bulbs on the Christmas tree, and here we are going to keep that tradition forward? Well, it’s time to gear up for the next season of Christmas being tech-savvy. Hence we have decided to brighten up a Christmas tree with the usage of Arduino Uno and LEDs in real life. Software to Install: To make our festival a little safer, we will first make our Christmas tree in the simulation and for that, we will u ...
Hello readers, we hope you all are doing great. In this tutorial, we are going to demonstrate how to interface and control a servo motor using an ESP32 board. After that, we will demonstrate how to create a webserver to control the servo motor’s shaft position with the ESP32 board. Servo Motors are among the most important actuators in robotics, with applications ranging from RC planes to automated door locks. Hardware components required A servo motor ESP32 development board Connecting wires Breadboard Servo Motor There are several specific types of electric motor applications in which the motor must rotate only at a specific angle. For such applications, we need a special type of motor with such a special arrangement that causes the motor to rotate at a specific angle for a given electri ...
Hello geeks, welcome to our new project. In this project, we are going to make a very useful and interesting electronics tool that we as engineers or tinkers need in everyday life. We use the capacitor in most of our projects for various purposes such as filters or power supplies. Most of the time, we do not have a provision to measure the capacitor value in our digital multimeter. So, this time we came up with the solution. Hence, we will make our own capacitance measurement tool using Arduino. Rather than investing in new electronic equipment, we will use an Arduino board and some basic components to measure the capacitance. To make this project, we should have some working knowledge about the capacitor. Here, we will not discuss the in-depth working of capacitors, but we will talk brief ...
We are familiar with multiple features of the ESP32 module. Like Wi-Fi capabilities, classic Bluetooth, Bluetooth low energy (BLE), inbuilt sensors etc. Hello readers, I hope you all are doing great. We have already mentioned in our previous tutorials that, ESP32 is also featured with a Dual-Core Processor. Which provides better performance and efficiency. In this tutorial, we will learn how to use ESP32’s dual cores. ESP32 has two (32-bit each) Tensilica Xtensa LX6 microprocessors namely, core0 and core1 which makes it a powerful dual-core microcontroller and hence stands apart from its predecessors. When we compile and upload a code using Arduino IDE, we do not have to worry about which core executes the code. It just runs. Fig. 1 ESP32 dual-core processor Features of Dual-Core processor ...
