Accessing peripherals problem

- Hello, and welcome to Code Clinic. My name is Kevin Skoglund, Code Clinic is a monthly course where a unique problem is introduced to a collection of lynda.com authors, in response, each author will create a solution using their programming language of choice. You can learn several things from Code Clinic. Different approaches to solving a problem. The pros and cons of different languages. And some tips and trips to incorporate into your own coding practices. This month, the problem is to create a musical instrument controlled by the mouse.

Move the mouse up and down to change the pitch. Move it side to side to change the volume. The instrument will be silent until we click and hold one of the mouse buttons. Letting go of the buttons will turn off the musical tone. It's a simple request, but because it requires access to the mouse, it may be difficult or even impossible in some languages. In all cases, we'll explore some ways to solve the problem and learn why they might not work. Thomas Edison observed, "Negative results are "just what I want, they're just as valuable "to me as positive results, I can never find the thing "that does the job best until I find the ones that don't." You may want to take some time to try to solve this problem for yourself in Ruby.

In the next videos, I'll explain how I answered this challenge.
