I’ll get a new cord to connect the PS to an outlet that is actually properly labeled/colored and go from there. Assuming any sort of standard coloring, connect white to N, black to L, and green to ground symbol.
Regarding connecting the LED strip to the AllPixel, I only have two cable connections on the LED string that I can connect to the 4-pin terminal. As far as I can tell, one is ground and one is +5V. Does that sound accurate? I don’t see anything I’d connect to Data.
How do I connect the power supply in this? Male to PS, female to AllPixel?
Again, thank you for all the help. This should be fairly straightforward but I am trying to avoid harming myself or the hardware with my lack of experience with this. Appreciate your patience!

You can use the barrel jack to power the first ~100 LEDs, not to connect the LED strip to directly. Though, yes… your power supply likely doesn’t come with that connector. In that case, just wire directly to the two wires coming off of the LED strand but make sure you ALSO connect the ground to the ground pin on that green connector on the AllPixel.

Sorry, I must be misunderstanding. You said you can use the barrel jack to connect the first ~100 LEDs, but I don’t see how you make that connection. Am I missing a cable I’d need to be able to use the barrel jack?

I’m glad I was on the right track in thinking the lack of marking on that PS power cable wiring was odd. I’ll just skip the risk and find another cable.
The LED strands are 50 LEDs per. When you say the barrel jack, I assume that is the actual name for the green piece on the AllPixel? To clarify, I use the two cables and not the male/female end to connect to that, right?
No… the green piece is a 4-pin screw terminal. That’s what you connect the LEDs to. The barrel jack is the black connector next to the USB port.

Adam,
I’m looking for a bit of clarity as the folks at the hardware store couldn’t help much and I haven’t found many videos online with a similar hardware setup. I have finally collected all the pieces and am trying to just get the hardware pieces connected.
I am simply confused on how the AllPixel, LEDs, and PS connect. (Here is some images for reference).
So my understanding is that the PS connection to the charger is done by linking the three ends pictured to the three rightmost connections, with the grounding connection going to the leftmost non-V+/- one labeled ± and the other two going to the N / L connections. Unscrew those connections, run the cable into the opening, re-screw the connections.
The wires you show for the AC power are not color coded. So I can’t help you there. Your plug wires should be white (N), black (L), and green (Ground symbol).
Not even going to speculate how the wires you have need to be connected because if you get it wrong you could die. Please find someone local who knows what they are doing there if you are not 100% sure.
I am a little confused about the LED piece. I understand the string is one-directional and that the AllPixel has to connect to the female end, but I do not understand where I connect the power to LEDs.
The pictures you show are also not color coded in any way on the wires. So no clue.
How many LEDs total on the strand again? You should be able to just connect to the barrel jack on the AllPixel for up to the first 5A (first ~100 leds). Then would need to connect power to the other end if you need more current.
Look how the connector is attached to the LED strand and see if there’s markings near the LEDs… usually 5V, G (ground), and D (Data). Those would match up to what’s labeled on the AllPixel.
Of course, the AllPixel connects to the Pi via MicroUSB.
So essentially, how do the LEDs connect to the AllPixel and to the PS? If you have any good reference resources that would be great, otherwise I tried to capture everything in the album linked for reference.
Apologies for my confusion as this is probably fairly basic.
Thanks!

Hi all,
I’ve had a Pi laying around for a bit doing some minor stuff, and have been looking for a cool project to try with it for ages. With Christmas season coming up, I thought to try an LED project using the Pi. I have a software background (in web), but no noteworthy hardware experience. I’m not looking to do anything huge, and with my background in mind, the less assembly of the individual components, the better. I don’t really intend to do more than 500 individual LEDs unless it is a series of strips or matrix that does most of that layout work for me.
With that said, I’ve been looking around and have gathered the following information about what is required:
- Raspberry Pi
- Controller (as apparent by the fact I’ve found this page, I’ve stumbled on the AllPixel/PiPixel to fill this role –
- Power Source (depending on the LED strip type, but probably requiring 5V minimum? So something like a 5V/20-60A/100-300W type amp?)
- LEDs – I am aware there is a choice of individual LED strings, LED strips, and matrices. I like the idea of the strings of LEDs for flexibility sake, but the convenience of the strips/matrix pre-made…
- Some sort of power cord to make the controller go
- BiblioPixel or LightShowPi for the software piece
Is this all accurate? Anything missing?Ultimately, I am just looking for recommendations on a decent starter kit that affords some flexibility, and some insight into the differences between some of the various options here (namely AllPixel vs PiPixel, BiblioPixel vs LightShowPi, and people’s experience with LED Strings vs Strips).
Tips and insight all greatly appreciated! Please let me know if I can provide any additional context/information.

definitely send pictures of how it’s connected. And what commands and project file you are running
