The original code sets up the blue LED on pin 13 as an output in the setup() function. In the loop() function, the LED is turned on for 1000 milliseconds (1 second) using digitalWrite(blueLED, HIGH) and then turned off for 1000 milliseconds using digitalWrite(blueLED, LOW). This creates a slow flash. To make the LED flash three times slowly, we use a for loop that runs three times. Inside the loop, the LED is turned on and off with the specified delays. After the slow flashing, we use another
