Hello, so I'm trying to control the speed of a DC motor with arduino. I'm using 3 buttons "mas", "menos" and "aceptar". As you can see in the code, the program is supposed to add 17 to the "velocidad" variable each time I press the "mas" button and substract 17 to the "velocidad" variable each time I press the "menos" button. The problem is that the Serial monitor only displays 17 orno matter how many timmes I press each button.

It seems I can't what is the definition of variable in computer terms any number to the variable. What am I doing wrong? Thank you. Thanks for the answer.

In Septillion's code, velocidad is visible at every point in that source code file from its point what is the definition of variable in computer terms definition to the end of the file.

However, if I remove the definition of velocidad from the point where Septillion defines it to inside loopas shown here:. This process, called encapsulation, makes it easier to debug the program if something strange starts happening to velocidad. The global definition of the variable means anything within the entire source file could affect it. Defining it within loop means anything affecting it must also be within loop. Encapsulation helps to isolate program definitino. Also, using the static storage specifier means co,puter variable is defined only once when the program first starts.

If you define a variable in a function with the static storage specifier, that variable will what are the limitations of e marketing its value between calls to the function.
