RESEARCH QUESTION[40 points]

18.Locate a graphical program that interacts with the user, using a mouse, touchpad, keyboard, screen, or any combination; that will start, stop, change speed, change direction, change color, or any combination. The program should be browser-based in any programming language or combination of programming languages.

– Explain the activity of the program

– Explain the interaction(s) [What is changing with an intervention.]

– List the programming languages used

– List the program source code

– State the function and section of the code that traps the interacting device. [The code will be tested.]
