using a potentiometer and building an inteface for it...
In a nutshell this week's ride:
Source a good tutorial
Build the board
Program it
Programing the interface in Processing
Final result
In more detail
If you are looking for an excellent tutorial on how to learn Processing, this is "the guy": see here I went through some of the chapters of this course. In approximately one or two hours one can have sufficient knowledge to build a basic interface.
This another great reference of one of those people out there that want to explain something very well, he does a very good job at explaining how to use Processing software with the Arduino IDE: see here. As you can notice in the image below with my code on Processing and Arduino both interfaces look very similar. This is because Arduino is mainly based off of Processing.
I built a new board using a breadboard. This helped me to review some basic concepts I was not really grasping by jumping straight to milling the board, and above all, it allow me to troubleshoot easily any issues with the board and focus on learning this week's subject.
As said, Processing has a great resemblance to IDE. See my code in more detail. I set the brightness of an image to change as a twist the potentiometer
