- This video shows using Pololu's addressable LED strip with an Arduino Uno. The specific LED strip used in this video has been replaced by newer ones, however, the general instructions for using the LED strips still apply. You can find all our LED strips here: www.pololu.com...
You can find the rest of the products used in the video at the following links:
* LED Strip (now discontinued, see comment above): www.pololu.com...
* Arduino Uno: www.pololu.com/...
* Wall Power Adapter: 5VDC, 3A, 5.5×2.1mm Barrel Jack, Center-Positive: www.pololu.com/...

If I want to drive LEDs why cant I connect bidirectional (dual polarity) LEDs to the servo outputs ?
This question doesn't seem to relate to the content of this video. You might try posting to our forum for general questions about driving LEDs: forum.pololu.com/
@@pololu I cant log in I forgot my password and It wont send me an email to change it. I tried many times.
hello a question Might give me a link where you explain the connection of arduino with mini pololu teacher 24 please not know how to connect and find nothing understandable thanks.
You videos are great. Thanks!
Does this WS2812b strip have to connect to a specific kind of pin? I heard that RGB LEDs require PWM-capable pins, but pin 12 is not a PWM pin as far as I can tell. I'd like to know which pins can and cannot be used on the Pololu A-Star 32U4 Micro.
Please note, the WS2812B LED strips do not use PWM signals; each LED segment on these strips have their own integrated driver that uses a special protocol (detailed on product page and datasheet). We answered a similar question for you on our forum:

thank you for your videos
17 seconds in you mention that you are working on the LED Strip page which is already open - unfortunately WE don't have it open and it is REALLY tough to find. I clicked LEDs and got to a page that had 'LED Strips' as an option, but that page only had items you are trying to sell. No resources.
It sounds like you were just looking at our LED strip category; if you click on any of those products, you will get to the product page, which has all of the relevant resources. Also, note that the URL of each page in the video is visible in the browser address bar.
Is the Arduino also powered from the 5v power adapter? If not how would you accomplish that? Thanks!
+furystylee In the video, the Arduino Uno is powered via USB (5V), but you can power the board in other ways. For details, see the "Power" section on the official Arduino Uno's page on the Arduino website:

Should the signal ground and voltage in ground share continuity on this strip? I understand this strip is very old and I am trying to trouble shoot if my issue is the hardware or example software. When signal ground is connected to the arduino I have no response from the strip after uploading until the ground is removed but the strip will not function properly. I have tried multiple arduino's and each example code with the same result: the first led is the brightest and will not change color and the rest flash randomly and get dimmer down the strip until the are completely out. I have used a digital multimeter to check and found that there is continuity between signal ground and voltage in ground. Any information you can provide will be extremely helpful, and if this system is too old to get data for that is understandable. Thank You.
Those grounds are already connected, and you should have a common ground connection to your controller from the LED strip. We suggest posting pictures of your setup and more details about it on our forum where we can further help you with troubleshooting your system:

Can you *PLEASE* do a Tut on how to program them to music?
Gaming For Research | Raising Money For Cancer Research Thank you for your suggestion. We do not have any immediate plans to make something like that, but many such tutorials already exist if you look around. Here is one example: czcams.com/video/0PgFK85fIHM/video.html
no longer on sale!?
Hey, Why did not you use any MOSFET stuff?
+Sarkrui What MOSFET stuff?
Kind of an amplifier that could let Arduino board to carry up a batch of 12V LEDs.I think that it has been installed inside the strip.
+Pololu Robotics and Electronics
+Sarkrui Each LED in the strip has its own built-in driver, so no additional MOSFETs are necessary to control them.
Gotcha thanks.+Pololu Robotics and Electronics
Does anyone have a link to addressable LED strips with one data line? I have zero interest in dealing with RGB LED strips. Would still love some awesome videos on unique projects utilizing addressable LED strips, specifically covering the code behind them.
Thats what these are. Its a single data line and two supply lines.
how i can connect 12 volt simple rgb led strip with 4 wires
+Random Games Media We don't carry any 12V LED strips, and the connections are probably going to be completely different from what we show here.
Can we use arduino nano Atmega168P in place of Arduino uno
Using the Arduino Nano should be fine in place of the Uno.
Easily, that's a 20 MIP microcontroller so it should work well. I can operate these on a 8 Mip microcontroller.
Excellent!
very nice .......thanks
Dear Emily, good day.
Just one crucial question for me.
Since the circumstances would not let me try changing components of my project and find why it doesn't work.....
This LAST pin you connected, the Dpin.....is there any value of V, A, or Ohms or anything else that I could read on a multimeter so I could know that the Arduino Nano I am using works????
Please help me, thank you for your time in advance!!
The comments section of a CZcams video is not an appropriate place for troubleshooting. Please contact us directly or post to our forum:

We also recommend reading our support page first:

Why is it discontinued?
It sounds like you are asking about the TM1804 LED strip linked to in the description of the video. Those LED strips were replaced with newer ones. We've updated the information and link in the description to reflect that. Please note that the instructions in the video still generally apply to the newer LED strips.
how program clockk
I like the way you are..
I wanna go HIGH one pin if connection of other pin disconnected.. would you like to help me?
+Muhammad Rehan It is not clear what you are trying to accomplish. However, the comments section of a CZcams video is not a great place for answering technical questions. If you would like help, I recommend reading through our support page: www.pololu.com/support
a "random" color that is explicitly set to 255.50.0 :D
super
Hello :)
Can u send me the sketch
A link to the Arduino library with included examples can be found under the "Resources" tab on our product page for the LED strip linked to under "SHOW MORE" above.
Pololu Robotics and Electronics you MUST get the apps open and laid out nicely BEFORE starting the video. i did understand everything but visually, this was disorienting.
Thanks for the feedback. Part of the point is to show how to get to various windows and pages. Can you give some more specific examples (times) of the video being disorienting?
you will notice that windows and graphics popped up all over the place and they were stacked (ie, obscuring each other). there might be some gui options for tiling, snapping to screen edges or corners, snapping to the edge of existing windows. like i said, get it open and laid out beforehand. just friendly advice, that's all.
