These days, it’s pretty much straight forward to simulate physical systems in a computer. Running those governing equations in any high-level languages such as Python, Visual Basic, Java, etc., make our life easier. Visualization of complex concepts of mainstream subjects is easier than ever before. Thanks to the growing community of coders!

But it is far more interesting when these computer codes interact with real physical systems which we can be touched and smelled! This opens up unlimited opportunities to probe and understand the complexities of a physical system easily. Successful communication between computers and physical systems is usually ensured by some external interfacing device which bridges the data processing between a computer and a physical system. This interface is capable of controlling and interpreting the signals to and from the computer. Though it was hard to implement such devices before, recent advanced technologies combined with novel inventions enable us to do successful interfacing effortlessly. Let’s begin!
