Beginner's Guide to Using LED Strips with Arduino

In today's tutorial, we'll show how to hook up the two most common types of LED strips to an Arduino, and control them. That's the 5050 single color RGB type, and the WS2812B ("Neopixel") individually addressable LED strips.

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.

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.

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

This is an incredibly useful video, thanks a lot.

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

[jakubnosek]

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

Great video. Is there a mistake in the diagram where the Arduino ground is connected to the 12V+? (black line)

[ChristianCristofori]

Regarding your advise at 1:16, how many could be powered via the Arduino UNO itself? And how many can Arduino manage when connected to and external power supply? Thank you, great video.

[aurorafrestadius]

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

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.

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 )

Ian - I REALLY like your teaching method. Where can I find some of your other content please. J.

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?

[sajidahmedchowdhury]

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

[hamnakashif]

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

[makeitathome]

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.

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

[milano]

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

[UnOrthodox_Christian]

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

[quemeese]

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?
