Hello guys!

In this lesson, we will play with Edison’s LED lights.

Can we program Edison to turn on and off the lights FOREVER?

To do this we will use a loop.

But what is a loop? A loop is a special Edblocks’ block. We can put a loop around other blocks.

Let’s look a little bit more carefully at what this program does:

The program tells Edison to turn on the LED lights..to wait for 1 second... then to turn off the LED lights...and finally to wait for one second.

The program would normally end there, but the loop tells Edison to go back to the start and start over again...and again…and again

Great! So let’s download our program to Edison and see it in practice.

Now that we have seen how the loop block is used, we can write a loop program that makes Edison move.
