Nowadays, many industries are using a level controller which means a level transducer for simply control the level in the storage tank, process control, and so on. In Industry what exactly happens is ( Basic Controller ) the person have to give a set point to the machine (eg. 70 ). Which can be set into a variable called setpoint for the machine. By using a simple PID controller we can easily able to control the physical parameters with the help of mathematical modelling.

Before explaining design, have to know about PID: What is PID?

Brief History of Control Systems:

PID is nothing but, which…

Here acquire a list of kali Linux hacking and penetration testing tools to access the security of the web, SQL mapper

Take a time to look Kali Linux, then you may know why kali Linux is one of the best Linux distributions for penetration testing and hacking. It comes with the bunch of tools to make it easier to test, hack and anything to do. Even forensics departments also uses this. Even a small company has official penetration test for securing their privacy data’s from the illegal hackers

Even the web-developer can able to use many number of tools for…

In the electronics industry, development boards play a major role for electronics enthusiasts and professionals. In recent days, many development boards are available out of which only some get to the top-notch positions.

On 22nd Jan 2020, Raspberry pi officially launched a new development board called RP2040. Raspberry pi Pico has a lot of new features and compactable when compared to other boards available in the market. Pi pico can be used by beginners and experts for various purposes from controlling applications to modern applications. Pico pins control the environment for our applications. Pico is compatible with C as well…

In our daily life mathematics plays an important role, which deserves much things to server, which is also know as mother of inventions. We all know the one great proved that is “Necessity is the mother of inventions” that’s why I said mathematics is necessity for creations. Mathematics which plays in all jobs and creations. Recently I studied a structure behind the mathematics, that concepts describe many things. We all know that the basic revert formula in mathematics that is which is my favourite formula also. But we didn’t know why the formula contains . One Basic thing was in…


A continuously variable transmission (CVT), also known as a shiftless transmission, step less transmission, pulley transmission, or, in case of motorcycles, a “twist-and-go”, is an automatic transmission that can change seamlessly through a continuous range of effective gear ratios. This contrasts with other mechanical transmissions that offer a fixed number of gear ratios. The flexibility of a CVT with suitable control may allow the input shaft to maintain a constant angular velocity even as the output speed varies.

A belt-driven design offers approximately 88% efficiency, which, while lower than that of a manual transmission, can be offset by lower…
