LED Strip Flickering? Possible Reason and Solution!

Ever had a problem with LED strip flickering while prototyping an Arduino project? Let's look at one of the most common reason and how to easily fix it.

Mine won’t stop flickering but they aren’t powered on by the remote they are just plugged in they turn of when I turn the plug of but I don’t know why

My LED lights are new and they flicker. They have a place to plug in the home power outlet. Whyyy is this

Hi! I need help with my LED lights and I can’t seem to find any videos about it. I recently got my lights like brand new 5 minute ago opened and I put it up. My dad like nailed some parts but between the lights where you’re supposed to cut on both of the lights. One of them is working but the other side works with some colors but on like green or white it starts dimming and is very dim or not even the color I selected. Help?

I keep unplugging and turning off and then plug back in and they just start flickering the color green for whatever reason and it won’t stop

Is this flickering visible to the naked eye, or are you specifically addressing the flickering that’s seen in video?

My led Flash intermittently when connected to my TV but works fine when connected to a mains. I think it’s because they are overloading? is there anything I can connect to the USB so I can have them on my tv, a reducer if there is such a thing?

My under cabinet system (designed and set up per supplier) has worked fine for 1-1/2 years and is now flashing. Wired parallel to three cabinets. Small kitchen.. The transformer is in my 89 degree basement. Could that be too warm for it?

Thanks bro! you solved a major problem for me. You made me realise the voltage drop in my 2 AMP wires - which were 2.5 metres long. So I switched to 7AMP wires and it worked!!

Thanks!!

we just had an led strip installed in our kitchen and it flickers when i turn it off after leaving it on for a few hours? any help or suggestions to make them fix it easier

Hey brother thanks for the vid... I have practically the same led strips, I have them connected to a 3 prong power switch, have been using them for about a year, have left them on over night and various hours at times. With no issues.... recently they just shut off. All power cuts off, even the light on my 3 prong switch goes out so obviously the switch is cutting off, but I don’t know why, if I wait a couple minutes the light switches on automatically on my switch and I can’t turn my leds back on but after a minute or seconds they power off.
The leds turn on and off soo I don’t think the issue is there... PLEASE HELP!!

p.s. I I’m to sure but I believe one if leds + & - we’re exposed and I think they touched metal witch could have caused this but can’t see. To fix it.
I’ve tried a new switch of the same but same results.
Thank you

every time I turn on the power supply (external) to feed 70 leds on one strip, I noticed that the leds flashed once. I'm not quite sure if that's normal. I then run the arduino to control the leds.

My led lights are smart ones and so i dont have a remote to turn it off but there is a button thing on the side of the strip but even when i click or hold on it it doesnt turn off

[caoimhes]

I cut my led lights and I put them back together with the adapter that came with them but the bit that I cut off won’t turn on. Any ideas why this might happen or how to fix it?

I’ve done 2 led bars straight to the battery with a inline fuse with a 3 pin switch under my car bonnet but now starts to flash how can I stop it ??? Relay? Or resistor?? Also plan on adding more bulbs to make the under side of the bonnet look like stars at night what would be best to add them with a switch

[yuchoy]

Well put. A common problem demonstrated and fixed. Thanks!

Hi, i just have 1 white channel LEDs. When I use the DMX decoder in standalone there is no flicker, i can switch on and off perfectly. When i switch to DMX control they flicker every 3 seconds. I can dim and play with which channel etc. all fine but the flicker. Any ideas? Question as well. I only connect via the decoder, 12v comes out and the LED is connected direct via 30cm of cable. You have RGB which I assume is why you have power in one end and DMX on the other. is this labelled on the LED strip?

I've been looking for a solution for a flicker free LED when filmed in slow motion (60fps 1/125 shutter) do you happen to know if these flicker in slow mo?

Hello new to this, just wanted to know, you have connected data pin and gnd in from of the led strip and giving power supply to leds from behind?

[PIXscotland]

Using the WS2812 series was a bad idea for this video. The worst flicker for these is the low PWM causing issues with video and in general when moving eyes across a scene. I'd recommend you split this video to add more details:

A. Power supply ripple caused flicker and the solutions.
B. PWM caused flicker and the non-solvability.

I know your video is named "Possible Reason and Solution!" but missing these obvious points isn't great.

my led strip flickers sometimes when plugged into a Samsung 5v 2.0AMP power socket, plz help FYI I have my LED strip along the topside of my 17” computer
