Hello everybody...

I am going to start saying that i never touched the arduino, but I'am very interested.
I am on the 3rd quarter cursing electric engineer, learning about resistors, capacitors, current etc

Well, i want to start a project, maybe all you guys are tired of people asking about Knight Rider lights, but I'm a big fan :slight_smile:

I have the Mitsubishi eclipse 97, my target is the spoiler lights, having the total of 40 red leds, that lights up whatever the brakes are pressed.

Question: 1 arduiono would be able to control 40 leds and make the "Knight Rider" effect with trail, believable ?

If yes, how I start ? Like arduino model, componets necessary etc

Any help will be very appreciated !

Thanks

Go to google.com enter:

site:arduino.cc knight rider

Or follow this link to the Knight Rider tutorial: http://www.arduino.cc/en/Tutorial/KnightRider

This is one way to get multiple outs where pins used < usable outs

Thanks for the reply, but the tutorial uses 6 leds, like i said, i don't know anything about arduinos, any suggestions of model, i went in the site to buy, but have different models, anyone is ok ??? and then, i need for 40 leds, can i do that with just one arduino ?

Thanks

The answer is in the second link. Use as many Shift Registers as you need to reach 40 (like (5) 74hc595's in series).
