MAKE Controller Persistence of Vision Effect with LEDs

Hello, this is my first instructable and I hope you like it. It's a simple project, using MAKE Controller (a very useful controller from www.makezine.com), that makes a persistence-of-vision-effect using LEDs. When you move the board quickly you can see two parallel lines drawing 'mountains' or continuous triangles.

The list of materials:

8 LEDs
2 220ohm resistors
MAKE Controller

Step 1 Preparing the circuit

First, you'll have to take 4 LEDs, 1 220ohm resistor and a few cm of wire and make the circuit shown below. When you finish the first circuit, just make a second one.

I've done it as my first project on this NI DAQ. working great! Attached pictures if some one is interested.

Oh, I forget, its programmed on LabVIEW (as you can see on the second picture)

That's nifty. Is it the 8ms sleeps that create the effect or somthing else?

[erfonz]

So it's like a persistence-of-vision thing?

[gerard_mp]

Yes, it is.
