Hello World Speedometer
Feb 9th, 2010, 7:15pm  
Hi everybody! I'm a total noob to Processing, and I've published my very first project here:

adam.theoherns.com/2010/02/09/simple-speedometer-v1/

My question is about code structure and cleanliness. As I grow and improve the program, I'd like to take advantage of OOP and/or any other organizational standards that would make the code simple and easy to read. Any suggestions for me with regard to my little program? Any advice you've got would be great!

Thanks a ton for a great open-source project, and a great community!

Adam -

I'm new here, too. That's a great start (I haven't gotten that far, yet). Still trying to figure out what I want to do. I've always been interested in speech recognition, but I have absolutely zero experience. I guess I have to start somewhere!

It would be nice to have that window to scroll to the left, while graph scrolls to the right.

Interesting... though I would think you would be better off calculating speed by just counting the "pips" and working out the distance from that?

Then just get your current speed from a set sample length (say, 0.5 second) - that'll be the frequency your display updates. Would be better if you stick more magnets on the wheel.

This is a really good start indeed. You could embed some parts of your code into classes, to make the whole thing easier to read.

What I like to do is writing the result I expect, then build the OOP skeleton around it (I also like to separate calculation and drawing in the draw() method, but you did that already).

I would expect something like this maybe :
Code:
void draw() {
  
  // measures
  bike.watch();
  timer.tick();
  
  // drawing
  background(255);
  Graph graph = bike.getGraph();
  graph.display();
  Stats stats = bike.getStats();
  stats.display();
  timer.display();
  
}
