Let's start with the basics.
Immersing yourself completely in a virtual world is the core concept of virtual reality. The technology creates simulated environments in which we can become a part and live that experience. We can create high-definition 3D and immersive content that is very close to real life.
Augmented reality is an enhancement of the real world. We mix the real world with virtual objects and that creates beauty (also referred to as mixed reality). It augments the real world with computer-generated virtual objects hence creating augmented reality.

Let's look at an example. When we hover the finger on the green button, the LED turns on.
When we hover the finger on the red button, the LED turns off.
When we hover our finger on either of the virtual buttons, our app sends the signal to the API. The API is further connected to the NodeMCU (I have used ESP32 hence the code will be a little different) which switches the LED on/off.
