nope the ground to the shiftbrites is connected directly to the battery - terminal .

so i went out and got a bigger voltage regulator to 7 volts and it is just doing the same thing only brighter !!! ????  smiley-eek-blue

Yes it is the battery + terminal all the positive leads are red and all the negative leads are black all the black leads are tied together through out the car and the - lead is attached to the - on the battery. Sorry for the confusion. Any thing else let me know sorry for the confusion.

grumpy_mike that is  good information i will look in to that. macegr, here is the schematic of the system any questions let me know.

not sure how to post pics on this i will attach the image.

I will get right on that tomorrow I live in england currently and it is 11 here need to get to bed I will create it and post it for you asap!! I also am running 18 shift brites with a single 5v 2amp converter thought it maybe not enough power ?

Hello,

I am currently in the middle of a project and really could use any ones help here!!!!

I am running the Arduino Duemilanove with ATmega168  connected to that is a 4-Channel 5V Relay Module for Arduino. The Arduino is running at 12v and the relays run on connected 5v out from the Arduino allong with the I/O pins which switch it on and off.

I have created tail lights from shiftbrite leds and they work great I have combine them with the 5v I/O relay system which switches the front blinker lights. The blinkers are LEDs that run just a strait 12v on so I use the relays to blink them.
 The problem comes when I connect the 12v power to the relay for the front blinkers ... all of the sudden the shiftbrites go crazy with a ton of noise in them all over?!?! When the front blinkers are not lighting (IE disconnected) the rear shiftbrites work fine?

I have connected the lights all the ways I can switching the +v and switching the -v for the blinkers shielding the shiftbrite signal wires, moving the relay board away form the Arduino grounding the lights in different ways.. hours have flown by with no idea left I need someone smarter than I to get fresh eyes on this situation.

Any Idea is a good one please help...

Thanks in advance

7  Using Arduino / Programming Questions / ShiftBrite Project on: June 01, 2011, 10:02:47 pm
Hello this is my first post on my first forum so hopefully I can figure this out!  smiley-grin

I am using shiftbrites in my car and I am having luck with them so far using the delay command. As I have come to find out delay runs in to problems quick when you’re trying to multitask. My question would be how would one use the millis() function to make them blink, in order to speed things up and smooth the look. I currently set up several different functions which switch depending on what button is pushed, but with the delay function it is slowing down the entire program when I am waiting for the delay function to execute and from what I have read the millis() function works better.

Any information would be greatly appreciated.
My programming experience is about 3 weeks old now so please dumb it down for me!!
Thanks  smiley-grin
