Control RGB LEDs with Arduino || Arduino Essentials #1

[@thecaptain8773]

This is one of the best technical vids I have watched in a long time. Well scripted, to the point, complete detail to make something simple happen which then opens the door for the user to do something more complex. Complete theory of operation at the functional level leaving out unnecessary / trivial detail that does not directly support achieving a specific result. BRAVO.

Did you like the idea of this series? I know there's a ton of Arduino videos on KZbin already, and I'm not sure if the topic is already too saturated. In the case that you liked it, have any ideas for what you would like to see in the future?

I have an idea. how about an led strip behind the dashboard of a car or inside of it that lights up and does a forward and back motion and then stays on when you switch on the ignition of the car. i have been looking for a video on this and cant find it anywhere. thats actually how i found this video. keep up the great work.

I gave 4 pin RGB led strip. How to wire it

[@snotvlek4721]

Good video! VERY IMPORTANT POINT, make sure your power supply can supply more amps than the LED strip pulls, you can check this by looking at how many leds the strip has, and since RGB LEDs take around 60mA, multiply the LED count by 60mA and you have the Amperage your PSU needs to supply!

I've had this video bookmarked for a while. Of course it's Xmas season, I'm staring at a couple of strips, and never realized how no nonsense this tutorial is. Thank you!

[@Sheepsville]

Thank you from the bottom of my heart for this tutorial. I have been working with my Arduino controlling actual LED components individually wired up to separate pins on the Arduino, which limits the amount I can plug into it. I bought myself one of these LED strips with 300 LEDs on it but I haven't had the time to sit down and actually go through how I control every LED individually on the Strip. You have saved me such a lot of work...thank you, thank you, thank you. I am now happy to sit and start programming my strip of LEDs to dance a merry dance 😊😘

Plug in the Arduino Nano into your PC!!!!. Thanks for the video dude, for everyone that was going through my pain on start-up you have to plug the Arduino into the usb port first (well that’s what I found worked for me!). Going to google search but hopefully I can get it working without the usb cable as I want to make a lightsaber with the Arduino nano in the hilt so plugging the usb cable in every time to the board is not ideal. Once the board is powered via usb i can take the usb cable out and the leds stay lit over a single 3.7v Li-ion battery I’m also running a 330om resistor in-between the data line as this takes less voltage so it's best practice to protect it. Took me so ling to figure this out because i didn't want to push too much current to the leds from both the nano and the 3.7v battery. anyway hope this helps some people :)

[@KalabawCNC]

love this!! I'd like to see a tutorial like this for controlling a max number of individually addressable RBG LEDs....like what is the max number of RGB LEDs that can be controlled? Is it possible to individually address 1024 RGB LEDs? or how about 2048? or 4096? what kinds of technologies would it take? what are the technologies involved in such a large setup? multiplexing? wires? drivers? Keep up the good videos! :-D

[@hejtmy]

There is no limit to LED theoretically. I think the major issue with so many leds will become power consumption, as most of them run on 10/5V only. I have a strip of 120 LEDs and it draws approximately 36W on 5 V, so you get 7A current. On 1000 that would be 70A. Very high draw from home sockets is I believe somewhere between 15-20A.

[@KalabawCNC]

I was mainly concerned about address-ability. Being able to individually address each LED, and what signal wire protocol. i.e. if using 2-wire serial communication how fast is the refresh rate to loop through each LED and set it's light value. If using a hybrid parallel/serial signal wire protocol with something like ethernet wire then what kind of refresh rate could be expected. If using a fully parallel wire obviously addressing loop time would be very fast.

[@KalabawCNC]

My other main concern is how would the setup/configuration be done for very large numbers of LED's before it becomes impractical for individual addressing. i.e. How do you do this kind of multiplexing? I've seen a lot of videos that say you just do it, but gloss over the implementation details. I like that you have all the details in this video and would like to see something that goes into greater detail on large scale multiplexing.

[@hejtmy]

If you do it through arduino, you don't care about the serial connection. You upload the script and it just runs on its cpu - aroudn 800MHz. through serial/tcp, you can only upload some simple commands that affect the loop, where you don't care about speed. the limiting factor in this case would be both the arduino and the led itself. I really have no idea. I recommend github.com/FastLED/FastLED/wiki/Overview to browse through their library. It's amazing and I used it for all my projects so far.

[@KalabawCNC]

Ahhh ok I just looked up the specs for the Atmega chip at 250,000 bps, and 16 bit serial address gives about 65,000 individual light addresses as the limit. But lets say a liberal estimate of 10,000 individually addressable lights on a serial signal wire. So that means to drive that chain we would have to send 160,000 bits which would take approximately 0.64 seconds, which is about 1.5625 hz refresh for the entire light chain as the theoretical limit. So my real interest is in how you could get this refresh rate up by using more than just 1 serial wire, and what would work best and how the implementation would work. Obviously if you use a 2-wire telephone wire you could probably get this to double since the data pipe would double. 250,000 bps down 2-wires rather than just 1. 4-wire security cable would double it again to update the chain in 0.08 seconds 12.5 hz. Ethernet wire would double it again and give you about 25 hz. I suppose that is acceptable refresh rate for most applications. And most applications will have less then 10,000 individual lights. ;-) Next interesting challenge is as you said, power, and of course programming. I'll have some fun when I finish building my Maker Lab space. Thank you for all of this! Good stuff!!

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.

Let's say I want to control 12 leds with arduino nano. So I connect them and create a colorful grading base animation that looks great. But in addition, is it possible to use a switch for each led that when pressed the corresponding led will change to white? All this without interfering with the base animation. Is this possible? I've been looking online but haven't been lucky enough to find information on a project like that. In other words, having an animation loop around the whole strip and when pressing (in example) switch number 3, the led number 3 goes fully white, while the animation still keeps going for the rest of the LEDs.

Yes..!! All microcontrollers have this function inbuilt..!! So, if you program/flash the code once ... Your Arduino board will always have the same code stored in its internal Read Only Memory. Just give the power to your Arduino Nano...and it will do the same job.... whenever you power it up. Hope I answered your question..??😊

Hi! Thansk for the video. Is there the way to divide the strip for two part: 3 of the leds light blue and other 3 light green for example

[@Kostanj42]

so i can also do led[1] = crgb(255,0,0); led[2] = crgb(0,255,0); led[3] = crgb(0,0,255); FastLED.show(); and first led will be red, second green and third blue?

[@ghans2305]

not quite, if i read the code correctly, the individual LEDs are stored in an array, which starts at 0. That's why in the function where he made them all turn blue for the first time, the loop counter "i" started at 0. so you would have to do led[0] = crgb(255, 0, 0); led[1] = crgb(0, 255, 0); led[2] = crgb(0, 0, 255); fastLED.show();

[@Kostanj42]

yeah i figured it out after many failed attempts..

[@gregorydavis8144]

is there something i can use to test my program before i gather my LEDs?? possibly using another linux program or so for a display with 5 or 10 "on-screen lights"?? my projects build isn't until later this year so I'm hoping to get the programming portion sorted, then change the number of LED's and associated "lights" coding once I have it ready to go...

I'm assuming from my (albeit quite limited) knowledge that the green wire is the ground. What would the second red and white wire be for? How would one wire up that LED strip?

Thanks for the video! I'm new to arduino and IDE but I'm looking forward to digging in. How much more work is it to actually address them individually in your code?

[@Nerdforge]

Thanks for the feedback. We actually address them individually, even though the effect is not so visible. When looping through the led array, each element led[i] can be given a different CRGB value, resulting in each led having different colors. Deciding how we want to give the leds different colours is more of a design issue when creating a project :)

[@FreshApplePie]

if you look at how for loops work, do you see when you set led[i] to a color? you're actually setting the led of index "i" to that color try it again and type in a number without writing the for loop, and you'll just change that led

Brilliant video :D Really helped a lot, but is it possible to program the Led's not to use the blue light colour?

Sure, when you set the color value using CRGB(0, 0 255), the positions of the numbers represent the color. First is red, second green, third blue. 255 is full, 0 is nothing, so this will output full blue.

[@paulglenny1714]

so after you do all the code can you run the strip without the arduino? or does the arduino need to be connected in order for the leds to receive the code?

[@Nerdforge]

The Arduino runs the code and controls which signals are sent to the LEDs, so it has to be attached. Else the LEDs will only hold a static color.

it has to be connected or on a different case you can leave the ATMEGA with out the arduino shield
