Hello friends, I hope you all are fine and having fun with your lives. In today's post we are gonna see Interfacing of EasyVR with Arduino UNO. In the previous post, we have seen Getting Started with EasyVR Commander. It was quite simple and if you follow the steps carefully you wont stuck anywhere but still if you into some trouble i am here.
Now this tutorial is quite a quick and important one as it contains the real code using which we will control our robot. After adding the voice commands, now close the EasyVR Commander and open the Arduino Software. Connect the arduino board with computer and double check that your jumper J12 in on position SW. You should also read Training Error: Recognition Failed in EasyVR, if you got such error while ...
Hi fellows! Hoping everyone is fine and doing great. Today, I am going to give you an Introduction to Induction Motors, the term which is very common and familiar but still many of us do not know it’s working and difference from other motors. Induction Motor is an AC electric motor, having a stator and a rotor just like other motors, but the working principle is a little different which would be discussed further. There are two types of Induction Motors, one is named as Single Phase Induction Motor, while the second one is named as 3 Phase Induction Motor.
An Induction motor is also called asynchronous motor, because the speed of rotation of its rotor is less than stator. In other words, it does not run at its synchronous speed. Before going into ...
Hello friends, I hope you all are having fun. In today's tutorial, we will create our First Web Application in ASP.NET Core. It's our 2nd tutorial in ASP.NET Core series and in our previous tutorial, we have had a detailed Introduction to ASP.NET Core.
We have also installed Microsoft Visual Studio Community Edition 2019 in our previous tutorial and today we will create our first web application in it. After creating this web application, we will also have a look at its files and will understand the contents. So, let's create our First Web Application in ASP.NET Core:
Creating Web Application in ASP.NET Core
First of all, start your Visual Studio which we have installed in previous tutorial.
A pop up window will open up, where you can open yo ...
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 ...
Introduction
We're glad you could join us for another lesson in our series on programming for the Raspberry Pi 4. The previous chapter covered how to interface the USB barcode scanner with raspberry pi 4. We looked at different types of barcodes and what each stripe represents as well as the different types of barcode scanners available today. We also built a python program for the intelligent shopping cart and now our familiarity with barcodes and scanners and how they function has significantly increased. The benefits and drawbacks of its use were also discussed, but what we're interested in for this article is the transmission of radio frequency signals using the nrf24l01 Module in a raspberry pi 4.

Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation. If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons.
First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.).
Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly).
Because of these two reasons, we have to use the driver in between t ...
Several manufacturing processes for plastic manufacturers and metalworkers, like milling or casting, produce burrs. However, to guarantee the safety and quality of a component, one needs to ensure smooth edges that will not cause any problems in further processing or use of the item. Deburring and brushing machines are solutions to this issue. High-quality deburring technology from Germany can be integrated into casting and cutting machines, and to automatically produce flawless components.
Deburring and Brushing Machines from Germany
What are Burs, and How do They Develop? Burrs are unwanted protrusions of a material like metal or resin that can develop during processing. When picturing a component like a gear, it is easy to understand, th ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to use Environment Variables in ASP.NET Core. It's our 5th tutorial in ASP.NET Core series. In our Startup.cs file, you must have seen that we have an IF Condition at the start and this IF Condition has IsDevelopment in it.
This condition is actually checking the environment of our web application. So, here we will first discuss them and then will see why we need them. So, let's get started:
Environment Variables in ASP.NET Core
ASP.NET Core has 3 builtin Environments, which decides the Run-time operating environment of the web application, which are:
Development.
Staging.
Production.
In order to set this Environment Variable, we need to ...
Indoor positioning technology has become widely available in a variety of configurations and quality levels. It's a jungle out there, and no single established solution, unlike outdoor location using GPS satellite technology, has been adequate for all needs.
Since GPS satellite technology became widely available in the late 1990s, positioning systems have played an increasingly important role in people's lives. Almost, everyone now owns a device with positioning capabilities, whether it's a mobile phone, tablet, GPS tracker, or smartwatch with built-in GPS.
Though GPS transformed outdoor positioning, we're now moving on to inside positioning, which will require new technologies. Because the signal is attenuated and scattered by roofs and walls, sa ...
Hello everyone! I hope you all will be fine and having fun. Today, I am going to share my knowledge about How to use MATLAB input Function. In this tutorial I would like to tell you about the importance of getting data from the user in MATLAB. If you want to display the data to users, you need to get data from them as well according their requirements. I hope you have read How to use MATLAB ?
In this way the same source code written in MATLAB will give different result according to the requirements of the each user. So, in other words the source code becomes generic in this way. As we run the program, command window of the MATLAB asks user to enter the desired input. The results on this window are generated according to the Matlab input given by ...
