I need a code works like the below video on unity:

* Full screen

* Receive an input from Arduino (I will add it later on), so the trigger for action in the code will be just an input from Arduino, for testing purposes keep the Arduino input as a comment in the code. and keep the floating object on all the time

* I assume the black screen is white and the floating objects are just a black figures

* adjustable duration to generate the floating objects

* adjustable speed for to generate the floating objects

* adjustable moving speed of the generated floating objects

* utilizes the random function in generating the floating objects

* utilizes the random function generating the floating objects
