arduino for loop

The for loop in C is used to execute a block of code repeatedly for a specified number of times. It has three parts: initialization, condition, and increment/decrement. Here is an explanation of each step:

  1. Initialization: This part is executed only once before the loop starts. It is used to initialize a variable that controls the loop. For example, you can declare and initialize a variable like "int i = 0;".

  2. Condition: This part is evaluated before each iteration of the loop. If the condition is true, the loop continues; otherwise, it terminates. It is typically written as "i < n" or "i <= n", where 'i' is the loop control variable and 'n' is the number of times the loop should run.

  3. Increment/Decrement: This part is executed after each iteration of the loop. It is used to update the loop control variable. For example, you can increment the variable using "i++" or decrement it using "i--".

Inside the for loop, you can write the code that needs to be executed repeatedly. This code block is enclosed within curly braces {}.

Here is an example of a for loop that prints the numbers from 1 to 5:

for (int i = 1; i <= 5; i++) {
    printf("%d\n", i);
}

In this example: - The initialization part is int i = 1;, where we initialize the loop control variable 'i' to 1. - The condition part is i <= 5;, which checks if 'i' is less than or equal to 5. - The increment part is i++, which increments 'i' by 1 after each iteration. - The code block inside the loop prints the value of 'i' using printf("%d\n", i);.

The output of this code will be:

1
2
3
4
5

I hope this explanation helps! Let me know if you have any further questions.
