Loop For Arduino

Introduction to the For loop

The loop FOR is the type of loop more simple, say that is a loop that since is starts know few turns will give (to difference of while that will stop when receive an event). It is declared in the following way:

LOOP FOR ARDUINO
for (initialization, condition, increment)
{
 judgments of the loop
}

Usually used to increase one by one and has this form:

for (int i = 0, i < 10, i ++)

Starts with i using 0, whenever just the loop is sum one and is running provided i be less that 10.

Basic code of a for loop for Arduino

Will use a loop for to create an effect of lights turning and turning LEDs from the pin 2 to the 13. The effect will be similar to the of the «Knight Rider» so dedicated to all those who live and grew up in the 1980s.

void setup()
{
  for (int i = 2, i < 14, i ++)
  {
    using the loop to configure the outputs
    pinMode(i, OUTPUT);
  }
}
void loop()
{
  We start in ascending order
  for (int i = 2, i < 14, i ++)
  {
    digitalWrite(i, HIGH);
    delay (500);
  }
  We put out in descending order
  for (int i = 13, i > 2, i-)
  {
    digitalWrite(i, LOW);
    delay (500);
  }
}
