Session 16: LED Looping Patterns with Quarky – 2

In the last lesson, we created a pattern using loops.

In this lesson, we will create an inverted pattern.

Let’s Code!

Follow the steps below to complete our script for the LED looping pattern:

Alert: Make sure that your Quarky is connected to PictoBlox using Bluetooth or USB.

1. We will start with the script from the previous lesson.
   
2. Duplicate the blocks from the set (Y) to (1) block and snap it at the bottom.
   
3. Now we have to do the following changes:
   1. Inside the first repeat () block, we will set the X to 7. We will first glow the LED on the right and then come to the left.
   2. We have to repeat the second loop 6 – Y times. For example, the second loop will run 5 times for the first time.
   3. Change the color of the LED to Red.
   4. Lastly to move the LED to left, change X by -1.

That’s it.

Run the script and test the code.
