Can you help me build an RGB LED strip strobe light for use with my levitating water effect project? The color combination of RGB strobe LED's must be selectable.

@jimweeks9359 4 года назад

is there any way to program the LED number so that once you clip off an section for a project you can start the left over strip at 1? Sorry. total noob with this light strip and Arduino. I have 2 strips of 72. they don't act like a strip of 144 when connected

@mertcapkin7263 6 лет назад

Hello everyone, newbie here :) I want to build something using the WS2812B LED's. Which wire gauge should be used if you want to cut the LED's from a strip and connect them together again? Will 22 AWG suffice? I would like to use 300 LED's in total, so total power consumption is 60mAx300=18W at 5V, so I would at least need a 4A power supply. Thanks! :)

@jordanfes 6 лет назад

60mA x 300led = 18A x 5V = 90W

@mertcapkin7263 6 лет назад

I know, I made some typos haha :)

@PowerMat81 5 лет назад

Itot=Iled*N°LED 0.06A x 300 LED = 18A !!! P=V*I 18A*5V=90W

@johnrobinson1140 2 года назад

a 60 led strip on full brightness wont exceed 1 amp so you'll need about 5 amp of power if all are on. 22 ga wire is fine

Hi Dejan , your LED projects are fascinating. It would be great if you could do an in-depth tutorial specifically on the hardware and then the coding needed for first an LED cube 8 x 8 x 8 and then the holy grail of all electronic hobbyist- The RGB LED CUBE , I think that tens of thousands of electronic enthusiast like myself would benefit from such an educational video- actually the subject matter is so complex in my opinion you would need several videos- maybe :-) Thank You So Much Jim

@KyleXY1975 8 месяцев назад

Thank you for the description you made about the ARGB principle. Before any work, is there a way to easily control if the LEDs are OK or not ? In my personal case, I bought an aRGB led strip to be connected to my motherboard (3 pins header with 5V). However it does not work. I checked with a multimeter the header, I have 5V on it. The MB seems OK. Is there a way to check individuallly a LED, while I don't have a lot of material on the table, a multimeter, few 1.5V cells. Thanks for your support !

@christopherpond3770 8 месяцев назад

Just FYI, the first thing you should do if your project doesn't work is switch the pin. My pin 7 wasn't working, but I switched it to 3 and the strip lit instantly. I'm using the Linux Arduino IDE, so maybe that's the problem, or maybe I burned out the pin, I dunno. Hopefully, it saves someone else some trouble.

Hello, i have a question. After connecting the Arduino to the LEDs, is it possible to remove the Arduino and make the LEDs work still? I am trying to make a product with a remote to change the lights when clicked, but having an arduino in every product would be really expensive.

@aaron4820 5 лет назад

Thanks for this! Got myself a pack of LED diodes which I thought was just a simple 4 pin RGB LED, which turned out to be a WS2811 8mm diode, was extremely confusing why it wasn't working when I followed other simple RGB led tutorials, and got to this which makes so much more sense! (and so much easier given I can control multiple of those diodes just by plugging them into a breadboard..!

@CBlargh 9 месяцев назад

How important is the resistor? I'm trying to light a single LED without it and failing. I know I'm talking to the board because I can flash the onboard LED and I know the strip is powered because I'm getting 5V at the end of it. What am I missing?

@BillyGates1721 Год назад

you should NOT connect Plus of the external power to the arduino +5V pin. If it happends that the external power-supply has a lower voltage than the arduino +5V-pin this situation acts as a shortcut which will overload the onboard-voltage-regulator of the arduino. Did you do test this situation thouroghly? As a "how to mechatronics channel you should do so.

@theputnamto3468 2 года назад

copied your sketch exactly, accept only including the first led, everything worked perfectly....the first time, after changing the code and reuploading the led stayed the same, after unplugging and plugging back in i got nothing. why doesnt anything in life ever fucking work for me? seriously, all this universe allows me to do is fucking work and sleep, im better off eating a fucking bullet.

@FrancescoCositore 6 лет назад

Great tutorial! Very useful!😉😉 just a note, in the project you should add some shift register in order to minimise the number of Arduino analog input so you will be able to use Arduino UNO board instead Arduino MEGA in the project.

@johnrobinson1140 2 года назад

or even a Nano, one 8 bit shift register would work

Could you run parallel led strips from the same signal line from the arduino if you have all powered by power supply. Will that require a different resistor for noise reduction?

@makeitathome1327 Год назад

Nice video! I'm actually trying to build an arduino project that can control an individually addreseble led strip that has 24 leds using an ir remote. I've got the code and components ready, but I'm worried about the current being an issue. Do you know how much power would approximately be needed, and if so, what gauge/ AWG wire would I need to handle that much current. Also, do you know how to connect a separate power supply to the circuit because I don't think the arduino can handle plugging a power supply into the Power Jack connector.

@NikhileshBhure 4 года назад

I have 2 strip of ws2812b 5meter. Total 10meter 60/m 5volt. Can you tell me which adapter will be better 5v 20amp? Or 5v 10amp? I m using arduino to program. Thanks

@KiwiMaker 4 года назад

wow i always wondered how they made individual leds turn on. I see my RGB strip lights dont have the tiny chips in them :(

@JNDlego57 4 года назад

Yes, the individually addressable LED’s each have the WS2812B chip, which makes the cost of these strips infinitely more expensive than the basic RGB ones you have. But they’re extremely useful, just be prepared to spend at least 2x as much for the same number of LED’s you could buy for the basic RGB strips. If part of your project involves just stationary uniform colors, I’d use the standard RGB strips for that

@Centauriel Год назад

Isn't the Data-In resistor supposed to be 33ohm (from the WS2811 datasheet) and not 330ohm (from the video) ? Does it make a big difference?

@juanbolivar35 4 года назад

Wonderful project. Thanks for sharing! Is there any type of proximity sensor that you can recommend? Since you uploaded this video a lot of new sensors have hit the market, including cheap microwave based movement sensors, to name just 1 category. Any experience with these sensors? Any advantages over the IR based sensors?

@viktr0643 2 года назад

Old video but I hope I get an answer: To what extent is this strip bendable? I need the LEDs to be closer to each other so I was thinking if the parts between each LEDs can be "wrinkled up" so that the LEDs would be closer. Or is there a specific cuttable programmable strip where the LEDs are closer to each other? Because I couldn't find one.

@tospori9652 3 года назад

Helloo, I am using the same led strip(20 leds total on the strip) with a 5V 1,5A Power Supply. I see that you used a 330 Ohm resistor but I only have 220 Ohm resistor, will I end up destroy my led strip with the 220Ohms or is it still ok?

@jakemiller8323 2 года назад

How does the strip specifically work? How is each diode individual addressable? Aka, what is the wizard behind the curtain of the “Fast Led”library?

@jasons5152 3 года назад

[Solved] My lights do not appear to be functioning the same with your code. The red and blue is disrupted by flashes of other colors. I verified correct connection; however, I did not use a capacitor. Is that why?

Actually, I had the 5v PSU connected, but I didn't include the 5v/ground pins on the Uno. It fixed it. Leaving this here in case someone else has the same problem.

If anyone is having issues like I was where you just keep getting "exit error 1" or something similar, you might need to update the board library, it took me too long to realise that you can still update the version 1.8.2 library without actually updating to a later one (which will also cause issues apparently...)
