- Hello and welcome to Code Clinic. My name is David Powers. Code Clinic is a monthly course where a unique problem is introduced to a collection of lynda.com authors. In response, each author creates a solution using their programming language of choice, mine is PHP. 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 tricks 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 is silent until we click and hold one of the mouse buttons. Letting go of the button turns off the musical tone. It’s a simple request, but because it requires access to the mouse it may be difficult or 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 the problem yourself. Is there a viable PHP solution? In the next videos I’ll explain how I answered this challenge.
David introduces challenges and provides an overview of his solutions in PHP. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
Visit other courses in the series to see how to solve the exact same challenges in languages like C#, C++, Java, Python, and Ruby.
