Engduino Lights Tutorial - Advanced

This tutorial will be a more advanced intro to using the Engduino.

Repeat all of the steps on the first page of "Engduino Lights Tutorial - Basics".

You should end up looking at a blank loop action like this:

Now create a for loop, from 0 to 17. Inside the for loop, set each LED (so LED "i") to white, followed

by a delay, then turn it off. You should end up with code looking like this:

This will create a cool pattern with the lights, where each light turns on and off, one after another.

Run the code on your Engduino to see!

Now use a while loop to do the same thing

backwards. Let's call your iterator (the number

that changes each time in the loop) "n".

You should start with n being 16, for the 16th

LED, and keep decreasing it each time for all

LEDs n > 0.

Now inside the loop, turn each nth LED on,

followed by a delay, then off again, like you did

above.

Don't forget to decrease n by 1! "n := n - 1"

makes sure each time you go round your while

loop, n decreases, until it hits 0.

When your code looks like the image above, try running it. You will now notice that you can do the

same thing with a for loop that you can with a while loop!

Well done! Now you've really got a grasp on how to use the Engduino, using some of the skills

you've previously learnt, such as for loops and while loops.
