By running 12v through the NeoPixel bar you have killed it as its only rated for 7vDC MAX!... So this is why it's not working for you...

Power the whole thing with 5VDC (4-7V works) and you're ready to rock.

If I had killed the sticks wouldn't it have stopped lighting all together? They still light, but I hadn't tried the 12 volt trick till after I had tried your updated code. On the regulated 5 volts from the usb when I plug them in they flash for a very brief second and off again.

Not necessarily as they won't work right anymore is all in your case. And a single flash, with 5v, is normal for when you power up the bar without a signal going through it; before you applied the 12v through it.

In order for this script to work the NeoPixel Bar/Strip DIN wire has to be connected to the Digital Pin 6 on your board(Arduino).

In which case before I applied the 12 volts it was wired that way. And it still does the flash without the signal wire even after the 12 volts, I may not have killed it but I'm not 100% sure.

Run the strandtest and see if it works with your bar; if not then your bar is damaged. Do you have another bar to try that you didn't put 12v through it?

.

Also I hope your using DC Current to power your Arduino and not AC Current; Because These electronics are only designed to use DC Current, And using AC Current will damage them and or kill them..

I just tried the stand test and it didn't work. But like I said it didn't work when I first got the sticks. I don't have another I can try unfortunately and I'm using a wall adapter like the one sold on adafruit except it has a switch on the face of the plug that switches from 3-12 volts and a range of settings in between. It's like something you'd charge your phone with but you can buy different tips for different devices.

Start a new thread and post pics on how your Bar is wired up to your Arduino and what your Arduino is(etc), and that your bar isn't working. I and others will help you there; as this thread is for help with my script. As you have a hardware issue. :)

really like what you've done and wondering if you would sell a completed setup?
could use it to liven up a black server room visible through a large window

Thanks You EternalCore for this ONE WAY code.

I know Arduino could drive many differents stripes using differents pin out.
Did you know how i can drive 3 differents stripes with differents colors and different wait_t for each stripes/pin out?

I follow this learn article there too if that's could help

https://learn.adafruit.com/multi-tasking-the-arduino-part-3/overview

The final goal is to drive 3 different segments of neopixel with One Way EternalCore code on 3 different pin out on Arduino.

Thanks

Code: Select all | TOGGLE FULL SIZE
-snip-

But now that I've removed the scroll down, the last two pixels at the end never turn off! I wonder what I did wrong...

Here you go I added a new script just for you, for what you are trying to do: https://github.com/EternalCore/NeoPixel ... OneWay.ino :)
To change the timing of between pulses change the number in int 'refresh', to change the speed of it scrolling change the number in int 'wait_T' and 1000 is equal to 1second.
-Enjoy
