Here we are to practice how to interface a function we programed on a board. As the following program shows I made an interface by making use of the processing software. And also wrote a code on arduino. The application is to turn off and on LED by making use if an interface display. See the pictures below showing the procedures I used to make the exercise.

The interface on processing run, the processing code and the rduino code

Applications one can export to from the processing. One also might need to install visual studio in order to run different applications from processing.
