The name WS2812B Strip usually refers to a long length of flexible PCB with many specific RGB LED Nodes evenly spaced and dotted along the top side of the PCB. Furthermore, WS2812B strips are fully addressable. This means each RGB LED node can display a different colour and intensity than its neighbours. WS2812B strips will do everything that non-addressable RGB strips do. In almost all regards WS2812B Strips are better as they allow for more creative LED light shows. Fancier animation/striping/chasing effects become possible when you can decide exactly what each LED Node will do. WS2812B can be referred to as NeoPixels or GlowBit LEDs. For the above reasons, WS2812B Strips are the best LEDs to choose in this form factor.
WS2812B stands for | World Semi | which is the name of the OEM (Original Equipment Manufacturer), followed by the name of the IC chip | 2812 |, followed by | B | indicating it is the 2nd big revision of this design. The IC Chips are built into each LED Node. Whether your WS2812B LED Nodes are connected on a rigid PCB or a flexible long strip the control system built in this guide can accommodate both. If you have never used a Raspberry Pi before, we have got you covered with our free, online Raspberry Pi for Beginners Workshop.

@ados380 8 ай бұрын
1:39 "General Rule of Thumb: A 5V 4A power supply can comfortably handle 150 LED nodes, at full brightness" 150 white LEDs at full brightness would take 9 amps. I haven't done any projects with LEDs yet, but I don't understand how this (5v 4a) would be the recommended power supply. Is it likely that someone is going to go full bright white with their LEDs? Nope. But if they did, bad things would happen, wouldn't it?
@devkigodara8778 12 күн бұрын
No . If your supply limits current then the strip will use only 4 amps but if its not then it depends on the metal in the strips . It might heat up or melt ! 😅
@nitzkit 11 ай бұрын
Pro-Tip: if powering the LED strip through a power brick, use a step down buck converter or a resistor to bring the 5 volts down to 3.6 volts. 3.6 volts is the actual voltage usage from the data sheet for these LEDs.
@nickcocca2210 9 ай бұрын
While it's always good to match the voltage, what is the actual benefit of doing this? Considering it's more material and setup, I don't see much point unless I'm getting a real benefit out of it. Would it use less power long term? Would it help the LED's last longer? Thanks in advance by the way =)

@chazaddum 7 ай бұрын
It's really cool approach connecting through the raspberry. I have a question: Is it possible to connect 10meters of ws2812 LED via external power supply of 3A but to reduce the LED count. I have 10meters (5 meters * 2) of 60 LED/m LED stripe. So due to the power consumption I want to reduce the LED count from total of 600 to 50. So 50 LED per 10meters. so instead of 60 LED in 1m I want to use only 5. Or to reduce power consumption in half. Because I don't have a 36A power supply

@Core-Electronics Ай бұрын
You can actually do this all on the same Pi! There is a little setup required though. The data terminals of all 6 strips can be connected together to form one long "chain" of LEDs. The issue is powering them as you can't power too many LEDs in a row. You will need to do something called "power injecting", which is basically where you just power the strips individually, but have the data lines connected. Then your Pi will see all of these strips as one long led strip it can control. I hope this helps, if you need any additional guidance, feel free to chuck us a post on your forums: forum.core-electronics.com.au/

Totally 😊 but note here - The longer a wire is, the more resistance it has. The more resistance, the more voltage drops along its length. Lower Voltage = Dimmer LED Nodes. So if you notice the Nodes at the end of your Huge LED strip are dim know that you can always provide power at both ends or at multiple parts along it to fix it. WS2812B do not mind what end/direction they receive power from. The data line moves in only one direction, but powering electricity can go either way.

I believe it’s due to how the strip accepts its data signal - as it’s a high speed, fixed rate, continuous stream of bits - and how the Pi can achieve that while also doing all the other things it needs to do (such as run the operating system). The libraries cleverly use the PWM of the GPIO along with DMA to be able to stream all of the data without getting interrupted. I’m only just starting on my journey of understanding these ARGB strips and how they communicate, but I think that’s the reason.

Does this work for WS2811 strings?
@Core-Electronics Жыл бұрын
Voltages are higher for those WS2811 Strings, which isn't a big problem you just need to be careful not to accidentally fry your Raspberry Pi as 12V will burn it out. Hit up our forum if you need a wiring guide 😊 forum.core-electronics.com.au/

If you are running bookworm os, they now require you to use a virtual environment. Here is a guide on how to do that: core-electronics.com.au/guides/raspberry-pi/using-virtual-environments-in-thonny-on-a-raspberry-pi/

Where did you find a LED strip with a Male 3-pin connector as the data input wire? I am in the US and I can't find a single one.
@RobertLipe Жыл бұрын
They're the same physical size as the two pin, power-only configurations. The third pin is used as the clock/data pin in the individually addressable versions. The non-addressible strips use R, G, B, Ground for 4 pins.
@theonlygamer5423 Жыл бұрын
@@RobertLipe It's not about the pins. It's the fact that in the US nobody sells a Male 3-pin connector as the data input wire. Instead I can only find Female 3-pin connectors.

i have a 5V and 3 Amp power supply for the LED strip. Is that enough?

Depends on how many LED nodes your powering + the type. But if your powering ~150 WS2812B LEDs then your absolutely going to be able to power them all 😊

Each RGB LED draws approximately 50mA when it is set to full brightness and powered at 5V. So your not going to get full brightness but truthfully they will be very bright anyhows. Come check this guide on powering heaps of LEDs from Adafruit - learn.adafruit.com/1500-neopixel-led-curtain-with-raspberry-pi-fadecandy/power-topology

@will300c Жыл бұрын
mmm are you sure about the power needed. Taking 144 in a 1 meter led strip will take 8.6 amps to run those leds at full brightness "white"
@Core-Electronics Жыл бұрын
Cheers for bringing this up. The provided code for the long strip drive the system at a quarter brightness. So we have 50mA Per Node * 144 Nodes * 1/4 = 1.8 Amps. That keeps us in a safe range for the power supply even if they get driven full white all done the line (a rare situation best suited to high power LEDs like these - kzfaq.info/get/bejne/qKqbg5xokqisiH0.html)

Alas doesn't seem to work with my led strip. also, kind of vague... since this is the only 'tutorial' i see on the internet. everyone seems to be using the same exact code. When I plug my roll of leds into it, none of the code seems to work right. oddly enough also having a hard time deciphering the docs for the adafruit code. =\

hi, was curious to ask, can i make a led scanner want to start at red, then white, then blue and start the process over again red,wht blue etc. i have 12v RGB led light strips. do you think this can be done with the raspberry pi 3? Ill be honest i didnt watch the video before asking lol. doin so now but any advice would be appreciated
