Join Dan Gookin for an in-depth discussion in this video Accessing peripherals, part of Code Clinic: C.
- Hello and welcome to Code Clinic. My name is Dan Gookin. Code clinic is a course where a unique problem is introduced to a collection of lynda.com authors. In response, each author creates a solution by 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 tricks to incorporate into your own coding practices. This chapter's problem is to create a musical instrument controlled by using 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 a mouse button is held. 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 may 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 solve this problem yourself. In the next few movies, I'll explain how I answered this challenge.
Dan introduces challenges and then provides an overview of his solutions in C. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
