Fastled matrix patterns

Pages: [1] 2. Multiple patterns running on one led strip - FastLed.

fastled matrix patterns

I'm trying to build lighting into my electric skateboard. I've got an Arduino nano and a APA strip underneath the board with 40 leds facing the ground lengthways down the board. The next step is to extend the strip to the front of the board so that I can also have leds pointing forward. I want these leds on the front to show different patterns to the ones under the board. I don't want to run separate cables from other pins on the board, as it means I'll have to run cables from the back of the board to the front.

If I simply extend the strip I can simply solder the connections that are already at the front of the board. I also want to be able to use one button to change the patterns underneath the board and another to change the patterns on the front of the board.

When I upload it, I don't get any lights showing at all. The code is below. Code: [Select]. Re: Multiple patterns running on one led strip - FastLed.

That code is written with the clock signal on pin 13 and the data on pin Have you wired your strip to these pins, if not change the line in the setup function to match how you have wired the strip.

Thanks Mike. You'll see in the code above that I have indeed changed the pins to match what my setup is: clock on 12 and data on OK, the problem is with the cylon pattern. It requires at least 64 LEDs in a strip. Just set the number of LEDs to 64 even though you do not have that many and it should run. By setting the number of LEDs to 64 you give the array that holds the number enough room to set what ever it has to do.

That worked. Now I need to figure out how to get 2 different buttons each changing the patterns or brightness on the different sections of the strip.

I need the first 10 leds to be the headlight and shine pure white, but to change the brightness between 3 different levels when I press button 1. I need the other leds to change patterns when I press button 2. Any guidance on this would also be appreciated. Well that code is showing 5 independent patterns, or it will when all the entries in the patternEnabled array are true. So you have already got a state machine. The first thing you should do in the loop function is to look at the buttons and get then to change variables.

Rather than make the patterns I gave as an example make your own, base them on my examples if you like.

You should see how they work. If you want a button press to increment brightness then look at the state change detection example in the IDE and have a variable that you increment and wrap round and use it to index an array giving the brightness number of each RGB element in the strip or section of the strip you are dealing with.

I've made some progress getting the button to move through the different patterns, but now I'm struggling to figure out why I can't get the code to loop back to the beginning and start the first pattern again. I've tried quite a few different options, but nothing seems to work. I keep getting stuck when the code reaches the last pattern.

I've tried another way and it's working better the first time I loop, but then it goes wonky.Using Arduino to simplify programming is nothing new. There are Arduino libraries for almost everything, and with one or more of these in hand you can make awesome gadgets, even as a clueless beginner.

One answer to this is LEDs that you can individually control with a low amount of wires independent of the number of LEDs. Along the strip there are either three or four electrical conductors, depending on the type.

Three of these conductors are supply voltageground and data signal. On some types of LED strips you also have a clock signal as a fourth conductor. These synchronous LED strips with dedicated clock signal are considered to be more robust than the asynchronous ones with only three conductors. There are many types of LED strips. The latter is some places rebranded as SuperLED. One very convenient property of these types of LED strips is that you can just cut the strip to any length you desire.

Just order a large reel of LED strip and cut off what you need for your gadget. All LEDs are individually controllable and the strip can be cut to desired length. With these three channels you are able to recreate any color.

These channels are often represented by 8 bits valuesbut not necessarily. HSV is another way of representing the same colors, but this is on the other hand an acronym for Hue Saturation Value. This can be a preferred method to work with since it sometimes parametrizes the color more clearly: hue decides if the color is red, blue etc. If the value channel is zero, the LED is turned off, no matter what the two other channels are.

You should always check your LED strip and see how much power it may draw, which is often specified as watts per meter or just watts for the whole length of the strip.

This number is for white color at full strength. You should also know how many LEDs per meter the strip has. We divide the power 18 by the LED density 60 and get 0. Then, we divide this number by the LED density 30 and get 0.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Arduino Stack Exchange is a question and answer site for developers of open-source hardware and software that is compatible with Arduino. It only takes a minute to sign up. Is there any central place that we can get drawing pattern functions for the addressable LED strips like the once based on the WSB component? These are sold on the Adafruit site under the NeoPixel name. For example I know of a few pattern examples like the Larson Scanner Cylona candle light flicker or a rainbow pattern.

However I could not find a single pattern repository.

I am working on a project for kids learning to program the Arduino and it would be nice to have all the patterns in a single place and to be able to switch between the program examples with a mode switch.

I have never found a single pattern repository, however FunkBoxing has a fantastic sketch with 30 or so patterns well documented. Thake a look at this library. In this video you can see some of the many animations available. Sign up to join this community.

I haven't tested it yet, so it might all fail miserably. I couldn't find much info about the flashes that fireflies make for this animation. It basically says that the color, duration, number of flashes, and interval all vary.

The example installation is close enough to call it complete. The Controls and power supply are in place in a little box I made out of plywood. The lights are installed under the top bunk and the light diffuser is installed. That was a simple rectangle frame I made out of plywood with a sheet stretched over it and stapled upholstery style.

In addition to writing to the leds, this library also includes a number of functions for high-performing 8bit math for manipulating your RGB values, as well as low level classes for abstracting out access to pins and SPI hardware, while still keeping things as fast as possible.

Tested with Arduino up to 1. Github likes putting -branchname into the name of the folder, which unfortunately, makes Arduino cranky! Here's a list of all the LED chipsets are supported. HL, and ""-style shift registers are no longer supported by the library. Right now the library is supported on a variety of arduino compatable platforms. Note that we have a long list of upcoming platforms to support, so if you don't see what you're looking for here, ask, it may be on the roadmap or may already be supported.

Support for upgraded compilers, as well as using AVR studio and skipping the arduino entirely, should be coming in a near future release. What types of platforms are we thinking about supporting in the future? Here's a short list: ChipKit32, Maple, Beagleboard.

However, since then, the library has expanded to support a number of LED chipsets that don't use SPI, as well as a number of math and utility functions for LED processing across the board. We use optional third-party analytics cookies to understand how you use GitHub.

You can use neopixel led strip or you can buy cheap led strip from market and what you need to do that remove the first led section of the led strip which having master controller. From next series of LEDs you can use as the neopixel strip.

But in chinese led strip one ic controls three led in series that means each pixel is equal to the 3 led pixel. If you write data on the first ic the three leds connected with that ic will lit up. So I'm using this type of cheap led strip which having 7 ic in series which controll 21 led as a bunch of 3 leds. By RishabhL www. More by the author:. Lets Begin. Arduino Uno 2.
