Implement button functions
- [Instructor] As you prototype, you'll begin to realize that you're using some of the same code patterns over and over. For example, the debounce code that we created earlier might be useful in any prototype we build that uses buttons. We can easily Copy and Paste this code from one sketch to another, but then we'd have to edit the code to reflect the pin number being debounced and the interval being used in the new sketch. Another way to reuse the debounce code from sketch to sketch is to create a debounce function. The function can be copied to different sketches, just like sharing the original code. But we'll see in the finished version that the function won't require any editing to reflect different pin numbers or debounce times. A simple version of the debounce function just uses the exact same code as the sketch, but the code is included in the function definition. A function definition begins with the function…
