Step 12 Click on the Start Simulation button to see the LED blink ON and OFF with the
specified delay.

Step 13 Click on the EDIT MODE dropdown button and select the Text option. The code you
created will be displayed here.

Here’s an explanation of the code you created:

void setup(): This is a built-in function in Arduino programming. The code inside the
setup() function is executed once when the program starts. It is typically used for initialising
things, like setting pin modes.
pinMode(13, OUTPUT): This line sets pin 13 as an output. This means that pin 13 will send
out electrical signals to control something (in this case, an LED).

void loop(): This function runs repeatedly after the setup() function. Everything inside
loop() will execute over and over again, allowing the LED to blink continuously.

digitalWrite(13, HIGH): This sends a high voltage signal to pin 13. In the case of an LED,
this will turn it on.
delay(10000): This pauses the program for 10,000 milliseconds or 10 seconds. The LED
stays on for this duration.

digitalWrite(13, LOW): This sends a LOW signal to pin 13, which turns the LED off.
delay(2000): This pauses the program again for 2,000 milliseconds or 2 seconds. The LED
remains off for this duration before turning on again.

The LED turns ON for 10 seconds and OFF for 2 seconds, repeating this cycle. This confirms that the
Arduino is correctly programmed and the circuit is functioning as expected.
