hi, my led connection only has a red and black wire, how would i be able to connect the arduino to it?

a great help ty!

Very nice project thanks 👍❤👌💯

Can i use a different power source to power the LEDs? If i used a long strip, will it work properly with your setup?

How can i do that without library

Very easy to follow thank you!

The URL in the description have expired. Can you update with direct links?

Are there other addressable devices other than LEDs. I am looking for something to address switches for piano keys.

3:25 / 7:36 AT THIS MOVMENT ONLY 3 LEDS ARE GLOWING,SO CAN YOU TELL ME HOW TO GLOW MORE LEDS? IS IT BY ADDING MORE FOR (int i=0; i<NUM_LEDS; I++) { leads[I] = CRGB(0, 255 - 20*i, 20i ); FastLED.setbrightness(6*i); FastLED.show(); delay(50); OR EDITING #define NUM_LEDS 60 TO #define NUM_LEDS AND NUMBER OF LEDS WE WANT TO GLOW

Ok so can i run 2 led strips of say 12 leds off one board by entering line 4 and 5 as 4- #define LED_PIN 3 AND 5- #define NUM_LEDS 12? Im trying to build a controller for light strips that are making diy wheel lights on my car :)

Very Helpful! Nice quick to-the-point video.

Thank you for this amazing explanation!

Any idea on how close those numbers can be, I.E. how many selections there could be while remaining reliable?

Could you please upload a tutorial with the code I have to do a project for school and I would like to do that but I don’t know how to do the code

thank you so much

thanks mate, I´ve had this arduino in its box since the pandemicum and now it will be turned into a VU meter for the studio

i learnt some programming today, also where is the addressing done how does next led light up from the previous one or any from the strip.

Great video. My question is how I would make a final/completed device? I want to make a gift for someone, and I want it to be where they plug the usb for power and it does its thing. But the device won’t have a breadboard. Like how do I minimize into a smaller package? I hope I’m asking the right question(s).

Can I use esp2022 instead of Arduino?

Amazing project and video, thanks. Can i connect led strip directly to the ESP? How WLED program works that it can power leds with no additional power source? No breadboard and no transistors in scheme?

BTW -never mind. I got this far (see below). Thanks again, this was a great video! #include <FastLED.h> #define LED_PIN 2 #define NUM_LEDS 60 int iR = 7; int iG = 155; int iB = 9; int iDelay = 50; boolean lDelta = true; CRGB leds[NUM_LEDS]; void setup() { // put your setup code here, to run once: FastLED.addLeds<WS2812, LED_PIN, GRB>(leds, NUM_LEDS); FastLED.setMaxPowerInVoltsAndMilliamps(5,350); FastLED.clear(); FastLED.show(); Serial.begin(9600); //open serial port } void loop() { // put your main code here, to run repeatedly: for (int i=0; i<NUM_LEDS; i++){ leds[i] = CRGB(iR,iG,iB); FastLED.setBrightness(15); FastLED.show(); delay(iDelay); } if (lDelta == true) { iR = 7; iG = 155; iB = 9; lDelta = false; Serial.println("lDelta was true, now it is "); Serial.print(lDelta); } else {iR = 155; iG = 7; iB = 9; lDelta = true; Serial.println("lDelta was false, now it is "); Serial.print(lDelta); } }

Greetings! I do have a question: In my case (and it looks to be this way in the video) at the start of the Void Loop, the lights blink off before continuing. Is there a way to have them never go out? Thanks!

Aside from the array numbering (yet, 0 to 59), this is a great video! Thank you for posting!

What about a .cpp file? I thought you needed one if you create a custom .h file

Could you run 5 lights from one arduino? I have a work project that requires something like this.

How did you come with the resistance and capacitance values

will this work with cooler master sickleflow 120?

Using the global attribute inside the function would make it work just fine, increasing n variable and so on. Why would you put global in global scope? Never seen that

can i use 12v strip in this manner

Also needed would be automatic update when selection in list box is made.

Thanks alot that file.close() solved my race condition issue while writing and reading in other .py file

I would move de FastLED.show() outside of the for loops.

Do we need a capacitor and a resistor ?? Is it must-need parts?

Saved me a lot of $. Turns out rotary selectors that are small cost like $15-40 each. But using a minature trimpot and this will work just as well. Thanks for uploading

May I ask if is it ok if I don't use a external power supply? my led strip is a 1m 60 led 5v (each led takes up about 0.3 watts). And I'm also using a Arduino pro micro

Hello! I am looking to learn how to connect an LED light strip to an arcade button so that when the arcade button is pressed, the LED light strip turns on or flashes a specific colour. I have looked online and it appears that an ardunio is helpful in doing this, but I am not sure how to make the connection, or what kind of hardware is needed. This is my first lighting project so any help is appreciated!

what is the function of "pass" in the class window?

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.

Perfect video. Thanks. 👍👍👍👍

This was soooo helpful! Thank you very much 💜

how do you this with out pack and use grid fro the labels and entries

I am trying to figure out to write the for loop so that there is a group of 4-5 LEDs moving down the strip, there is a delay, and then another group of 5 LEDs that start down the line. Any idea where I can find an example of how to write this to achieve the desired effect?

Tq for sharing. Suggestion: Extend the idea to animating the plot with a time base.

Sir how to add data's in treeview ,listbox,textbox using xlrd and xlwt and openpyxl.please teach me sir

can you hook up 2 led strips by just wiring the second one the same way as the first one using the same pin on the arduino? I am making a lightsaber with them, and I want 2 strips so I can stick them back to back and make a more evenly lit blade

This is exactly what I needed! Button tutorials seemed all over the place and they didn't get to the base of why and what. This is amazing. The only thing I missed is understanding what the digital in pin does to determine if the signal is high or low. Is it if the signal is between a certain range

How to operate this with a switch

how do you do it with r+?
