Noobie looking for help.

I am a art student who is trying to create a project using the basic adruino kit. I don't know much of the logic behind the coding because this is something that is completely foreign to me, so if possible, some one please help me.

I'm trying to make 10 LED lights to brighten and dim about 1~2 seconds apart, and having some relapse time in between them. and repeat.

Kind of like: 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5, and repeat

How would I do that?

Thanks!!

try to look at this tutorial

http://arduino.cc/en/Tutorial/Fading

I'm sure that you can figure that out.

Thanks for the link!

However, the Code part of the page is missing. I think the link on the site was somehow corrupted so it doesn’t show.

Is there another site I can go to?

I was able to retrieve it for you…heres the code from the above link:

/*
Fading

This example shows how to fade an LED using the analogWrite() function.

The circuit:

  • LED attached from digital pin 9 to ground.

This example code is in the public domain.

*/

int ledPin = 9; // LED connected to digital pin 9

void setup() {
// nothing happens in setup
}

void loop() {
// fade in from min to max in increments of 5 points:
for(int fadeValue = 0 ; fadeValue <= 255; fadeValue +=5) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);
}

// fade out from max to min in increments of 5 points:
for(int fadeValue = 255 ; fadeValue >= 0; fadeValue -=5) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
}

Thanks Arduino4HS!

The other day none of the code (on the site) was working, but it all seems good now :)
