The value of k corresponds to the index number of elements inside the array (LED pins). As above in void setup, as we use for loop to declare all LEDS pins as OUTPUT, the same we will do in the void loop to turn LED ON and turn LED OFF using the digitalWrite() function. In the void loop, we continuously turn all LEDs ON in a sequential manner and turn OFF LEDs in opposite direction. So using while loop we have declared each LED pin of Arduino as OUTPUT In the while loop, we initialize the value of k as 0 first and later increment till the value of k reaches the total length of LED which we have declared as 10 (i = 0 to i =10). We will use a while loop to declare LED pins.

Here we have 10 LEDs so instead of declaring each 10 LED pin as output. We have to declare the LED pin as output. In the void setup, we have configured the baud rate to 115200. We configure pins as INPUT or OUTPUT. We will take a small example of a while loop by glowing an led

if the condition is not satisfied then the code will jump out of the while loop and the remaining code will be executed. this process is repeated until the condition is not satisfied.

now again it will check in if condition whether value if i is less than 5 if condition satisfies then we will print the value of i and increment it.

In the while loop first, we initialize the value of i and assign a value to it (i=0), inside the while loop we check the condition if the value of i is less than 5, if the condition satisfies then we will print the value of i and we will increment it, previously the value of i was 0 after incrementing it will change to 1. Int timer = 100 // The higher the number, the slower the timing.While-loop is the same as the for-loop, the result and the operationĪre similar to the for-loop but the difference is the length of the lines. This example code is in the public domain. Lights multiple LEDs in sequence, then in reverse.

Watch in awe as your LEDs turn on and off in sequence.

The button will turn orange and then blue when finished. The button will turn orange and then blue once finished.

Using a jumper wire, connect the common power strip to a GND pin on the Arduino.

Add LEDs and resistors in this fashion through pin 7.

Connect an LED in the same manner – make sure the short leg goes in the SAME power strip column as the previous LED.

Now connect a resistor to pin 3, and put the other leg in a row on the breadboard (a different one than your first LED).Connect the short leg of the LED to one of the power strip columns on your breadboard.Connect the long leg of the LED to the row in the breadboard where you attached the resistor.Connect one side of a resistor into pin 2, connect the other side into a row on the breadboard.

In this example, we are setting out to make a row of LEDs light up somewhat similar to Kit in Knight Rider. A for loop repeats an action for a specified number of iterations, reducing the lines of code that need to be written thus making the programmer’s life easier. There are few functions so useful that you find them everywhere. Arduino Course for Absolute Beginners For Loop Iteration
