Arduino For Loop

The for loop is a fundamental programming construct used in Arduino programming to repeat a set of statements for a specified number of times. It provides a compact and efficient way to iterate over a range of values or perform a repeated task.

Syntax

The syntax of the for loop in Arduino programming is as follows:

for (initialization; condition; increment/decrement) {
    // code to be executed repeatedly
}

• Initialization: The initialization statement is executed only once before the loop starts. It is typically used to initialize a loop counter variable.

• Condition: The condition is evaluated before each iteration. If the condition is true, the loop continues; otherwise, it terminates.

• Increment/Decrement: The increment or decrement statement is executed at the end of each iteration. It is used to update the loop counter variable.

Example

Here's an example that demonstrates the usage of the for loop in Arduino programming:

void setup() {
    Serial.begin(9600);
}

void loop() {
    for (int i = 0; i < 5; i++) {
        Serial.print("Iteration: ");
        Serial.println(i);
        delay(1000);
    }
}

In this example, the for loop is used to repeat the block of code five times. It initializes the variable i to 0, executes the code inside the loop, increments i by 1 at the end of each iteration, and terminates when i becomes equal to 5.

The code within the loop prints the current iteration number to the Serial Monitor and adds a delay of 1 second using the delay() function.

Break and Continue Statements

The break and continue statements can be used within a for loop to alter its normal flow:

• The break statement is used to exit the loop prematurely. When encountered, it immediately terminates the loop and resumes execution at the next statement after the loop.

• The continue statement is used to skip the remaining statements within a loop iteration and move to the next iteration.

Conclusion

The for loop is a powerful tool for repetitive operations in Arduino programming. By understanding its syntax and usage, you can efficiently perform tasks that require iteration and control flow in your Arduino projects.
