Beginner's Guide to Using LED Strips with Arduino

I connected the Drain of IRFZ44N to the LED strip (Red color ) and the Source to Ground (of the 12v DC power supply) and even before I connected the MOSFET Gate - the Red LED light lit up !

Double checked it - so it looks like the Drain and source is OPEN ! and the Gate has no effect.

The 12v DC adapter is connected as follows: The Positive is connected to the Power Line of the LED strip, and the GND is connected to the Gate. ( It's a Barrel connector on a hobby pc board )

dang i wanted to do the stuff with neo pixels but i dont

Could anyone get the 5v working? I did everything right and nothing

but how to interface R G B 12v type LED strip with arduino how to connect them?

Thank you so much, this was very informative and to-the-point. instant sub

Thanks for this video, exactly what I needed to get started.

Hey! Maybe a stupid question but, will i burn something up if i skip the mosfets? i have a 5v strip, and i just want it to turn on a color, no need for controlling brightness and such.

thank you .. it was really helpful.. Is it possible to get 3000k warm light in WS2812B instead of rgb

This is an incredibly useful video, thanks a lot.

Can you do this in Matlab

very nice video ... Can I also control two separate RGB LED stripes? In my case 2 times 1 meter. I want to build it into my Virtual Pinball.

would this work with an IRFz44N Mosfet?

Do you think i could light up a certain length of the strip based on a distance reading from a sensor? Like the carnival hammer game, an object flies up and the LEDs light up as it goes up.

I have a 12v strip with only 3 connections. Does this need a MOSFET onthe data line? Can't find any data on this strip bought from eBay some time ago! It comes on white when no data is sent to it!

Percent Just what I need. Everything I need to know Thank u sooooo much! 😀😃😄😁😆

How many control led by Arduino can 900 led control by Arduino

Thank you so much, I've watched countless videos on this an this made it so much easier to understand.

Where can you get the WS2812B for ~$4/m? Best I've seen is ~$10/m for 30 LEDs/m

If i have 5v led strip is it necessary to put mosfet and external power supply or i can directly power it via my arduino ?

Hi! This is a great video to make me understand easily. I have a question if they have included the servo motor??

Does the Arduino need to stay connected to the LED strip in order for the programming to work, or does the strip have memory built in?

What did you use for your power supply? Is it just a 12v power supply plug that you cut and fit in? And would I need to make any other adjustments for LEDs that need 24v besides the power supply?

What would change with WS2811 12V strip? Capacitor should be 12V? How to choose the right resistor?

Chips model ?

I actually watch this video with my own WS2812B set-up running. As an electronics and gaming pc enthusiast, I had ARGB, arduino (elegoo uno r3), resistors / cap at home, just waiting for me to put it all together thanks to your guidance. Like always, my favorite part is soldering the JST SM 3 pin connectors to the RGB strip.

What is this big capacitor used together with the WS2812B LED strip for? Is it really necessary?

do you know if this could work with 24v led strips?

I cannot figure out how to program my Kaimana mini. i wish there was a software of a GUI webkit available. Jensen Khameleon webkit site is down. I’m looking for an alternative

Expected primary-expression before '=' token how do I get it to work

Where can I find the LED strips? I couldn't find a site that sells only the strips for a reasonable price

I set this up with a Nano, using Digital ws2811 WS2812B Addressable smd5050 5v led bar light and using a 360.00 ohm resistor with a 100uf cap and i am getting flickering and signal loss quickly. it can only run the first 5 of my 64 leds with a 2A power supply, and it really is only effectively working 3 of them. Any ideas what i am doing wrong?

Thanks a bunch! Works excellent!

Thank you!!! Very informative and clear video, just the one I needed :)

Does it work with nedis rgb strips?

Is it possible to program a led list so I can change the color on the ledlist at a specific place? I want to have a ledlist around my table top tv case and be able to change the color at a players position to indicate its that players turn to act.

Hi, I'm new to Arduino. This tutorial is great for a project I'm considering. I am making a dice tower where I'd like to run an IR sensor, small speaker, and a small amount of LEDs from an Arduino. My goal is so that when you put your dice in the top of the tower for a roll, the IR sensor gets tripped and a few sounds play and the LEDs flash in. some pattern. I'm pretty sure this is doable but I'm wondering how I would fit the Arduino, a ring of led lights, and a breadboard in the base of the tower. Should I get the breadboard printed so its smaller? I only need 5 or so if that's the case. Suggestions for saving space?

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.

Is it possible to use a Arduino board to detect when a variable of 1 - 12v is present to turn on/dim a Led Light? For example I own a limousine and I'm wanting to redo the lighting but still be able to use some of the controls inside the Limo. There are knobs in the back seat for bar Lights, Interior Lights, Mood Lights and Halo Lights. I want to upgrade from fiber optic to Led strips but I am having a rough time Finding something that will work for my application, I want these lights to be able to sync up with Each other. I plan on getting a diffuser for the led lights Aswell to give them that neon look, but right now I am just trying to get a idea of how I could go about this and get everything setup.

Do you need those mosfets or can you use other transistors like s8050?

is there a way to set up a LED strip that each light would singly light up one by one in sequence until all are lit, then stay on until power is disconnected? preferably in all white?

I can’t get the code to compile. It’s mad at delay(delay(fade speed); it said invalid use of void expression

I would love a tutorial showing how to synchronize an Arduino controlled LED with MIDI controlled DMX signals. The idea would be to take a DAW like Ableton, which can control DMX lights, synchronize the DMX signals to react to MIDI notes so the notes control the lights, and then feed those DMX packets into an Arduino script for adaptive, dynamic light shows synced to a MIDI interface/track. Doing this would allow musicians to build cheap LED light shows and even, perhaps, LED Matrix walls, which can either have preset displays or real-time MIDI display.

Great work, thanks.

Im planning to make a leviathan axe from god of war, and I'd like to have the runes actually light up, and ideally pulse/move about

Thank you. Very helpful for starting.

why do we need MOSFETs to interface the LED strip with the Arduino?

Tried this same circut with a 24v strip and it didn't work with the 10k resistor, removing the resistor makes it work. Do I need a different value for 24v? Is it okay to run without the resistors?
