  • 50 meter long LED strip

    Hi Im a bit of a newbie at all this but im looking for some advise. My main aim is to run a 50 meter long led strip at the bottom of a swimming pool. I was hoping to use the arduino to control the led strip so that it lights 16 LED’s (8 along the strip (2 side by side))at a time going from one end of the strip to the other in a set amount of time that i specify.

    I was looking at 1 set of 2 leds(side by side) every 4 cm. That a total of 2500 leds in the strip

    The programming of the arduino i reckon i could do. But its the sheer ammount of leds and the controlling of them that im struggling with. As i said at any one time only about 16 leds will be lit at any one time. Does anybody have any ideas how i could control these. I dont think i need to worry about voltage drop as not enough will be lit at the same time to worry about it.

    Any advise will be much appreciated.

  • Hi, I just bought an Arduino (Uno) and I'd like to use it to control a LED strip ! I'm good at programming but electronic is just a new world to me ! I read that I can't just plug my strip in the pin of my Arduino 'cause it's gonna burn it... Furthermore, the strip needs 12V. The strip I ordered is 5meters long (36W 150 x 5050 SMD LED RGB Light Flexible Strip (5M-Length/DC 12V)) I've seen some solutions here and there, some using MOFSET, some using ULN2003, others using amp. I've also seen people complain that their led are never completely off... I was going ...
    I started a new project that involves Arduino and LED strip. I want to control the strip wirelessly. Can I just feed the SPI signal to one xBee and connect the output of the other xBee to LED strip? Or I need Arduinos on both sides? I'd like it to be really fast. I was thinking of programming Arduino on receiving (LED strip) side with different functions I need and then trigger them with Arduino on sending side. But if I can do direct SPI, then I don't need 2 Arduinos. I have 2 60mW xBee Series 1, Arduino Uno, ...
    Ok, so I've been fighting this for a minute myself. The first mistake I made was assuming the wires and connector were on the correct end of the LED strip. What I got was the tail end of the RGB strip with the lead to connect to the next strip. The way I discovered this was that nothing I did made any leds light up except when I accidently ran my finger across the open end (the one without the leads attached) of the strip when powered. My finger toggled some leds in the strip and since latch didn't get ...
    I just bought an addressable LED strip that uses the TM1903 chip. The strip only has 3 cables: Vin, GND and DI. I connected Vin and GND to the 12V power source and the DI and GND to the arduino. I don't know how to send the 24bit signal to the strip in order to control it. Can anybody help? Here's the chip: http://www.szpth.com/p/zl/TM1903.pdf And this is the strip: http://www.kutop.com/led-strip/intelligent-ic-rgb-5050-led-strip/magic-dream-color-intelligent-1903-ic-rgb-5050-led-strip.html
    Can this be done? I thinking that because these strips maybe wired in parallel, I would NOT be able to control each LED, but maybe I could control each strip. The reason I want to use these strips is because they are super cheap!! And...I need a strip of LEDS. 24 on each strip x6 strips exactly. 24x6 Can each strip be controlled by the arduino? If so how? I need a good start or some direction. Never used one of these suckers before, and Im afraid Im in over my head. But I like to run before I can ...
    Hi there, I have the following project in mind: wire an led strip to a bike dynamo - the faster the user pedals, the more LEDs light up. So the led strip would be a direct indicator of how fast the user is going. This is for an ecological project, so I'd like to use manpower only (if possible i'd like to avoid using a circuit to boost the output voltage). If anybody has any feedback on this problem I'd really appreciate it. The led strip would have roughly 50 LEDs. Thanks, N
    Hi! I'm new in the topic of microcontrollers etc.. I only have plenty experience in programming. I want to build this: http://www.instructables.com/id/30-channel-LED-RGB-Ambilight-Clone/?ALLSTEPS Today I've connected a little piece of the RGB LED strip with an external power supply and the Arduino. I did it like in the image at step 2 in the link: +12 V Power Supply --gt +12 V LED Strip GND Power Supply --gt GND Arduino To control the LEDs I've connected the 3 colours from the strip to PINs 9 (red), 10 (green) and 11 (blue). My main problem at the moment is that all LEDs are shimmering even if I set the ...
    I am kind of a noob when it comes to programming, but i know a little. Can some one help to change this code so that i can control 2 separate strips simultaneously running different variations of the colorWipe() function. Thank you Quote #include "LPD8806.h" #include "SPI.h" // Example to control LPD8806-based RGB LED Modules in a strip /*****************************************************************************/ // Choose which 2 pins you will use for output. // Can be any valid output pins. int dataPin = 2; int clockPin = 3; // Set the first variable to the NUMBER of pixels. 32 = 32 pixels in a row // The LED strips ...
    Hello! I am interested in triggering a LED strip with an accelerometer. I have bought a 12V LED strip, and I am wondering how to convert the 5V in the arduino board to 12V. I just read about transistors, and replay switches. Could i possibly have the thresh of the accelerometer trigger the transistor to open up the 12V and turn on the LEDs? The ideal situation is that when a certain amount of force or velocity has been reached, then the LEDs will flash on. Any thoughts here would be lovely. :
    Hi guys, I want to control RGB strip (12V and ~2A) with my arduino. Im beginner in electronic, but I read that IRFZ24N should work well for my project. But Im tinkering many hours around and cannot succesfully connect things together. 1. Arduino works. Im using simple LED blink example - and just want to make my strip blinking like builtin LED in arduino. 2. LED strip works. 3. IRFZ24N works - when I connect gate to 0 or +12V of my power supply, LEDs goes on and off correctly (I know +12V is too much for this transistor, but it is still alive). When I ...
    Hello, I would like to know how to connect LED Strip to the Arduino Duemilanove and how I can control it. LED strip looks like this: http://www.elmo.lt/553-1298-thickbox/5w-1m-led-strip-non-hermetic-cold-white-light-3528-60-m.jpg
    I've browsed the other posts regarding the digital rgb strip... I started working with a strip of 50 LEDs. Added the proper number of LEDs in the basic library code provided. Connecting the GND as in the tutorial using an external 5V 2A power supply (http://www.adafruit.com/index.php?main_ ... cts_id=276) Got mostly white lights. The 2 LEDs closest to the input wiring were off. Messed around w/ different numbers of LEDs, 48, 49, 50, 51, 52, 25, etc... the lights obviously still acted weird, but the first 2 ones still never came on. I figured that the first two ones were busted somehow, ...
    first a bit of the kit. This is for LPD6803 LED pixel strings. Using IDE 1.01, arduino pro mini, 80 pixels, rotary encoder, DS2331 Real Time CLock. What I am doing with this code: I send this chunk a few variables to control which LEDs are on and when. (digits, a,b,c,d) setCircle(); calls a subroutine to advance the position of a lit LED in a circle of 20 leds (the last 20 on the string) what I am trying to do: eliminate the delay(); statement, as it affects the speed of the setCircle routine (which is already has ...
    I just got a 5m strip of l.e.ds in today, my question is Im going to be outlining a triangle 16x16x16 there are three l.e.ds every two inches so would one Arduino be able to control these l.e.ds? If so does anyone have any advice on how I could power it? It seems you plug the strip into the power supply so Im kind of lost there I'll be using two 16x16x16 triangles so if the Arduino can control one side, can it control both? I want to be able to flash, strobe, knight rider etc etc. Also does anyone know ...
    Hello everybody, I want to make an electronic Monopoly, I need to stick a LED in front of each squares to tell if it's free or not. I need at least 36 RDB LEDs or 4x9 RGB LEDs that can be addressable. I've found a 32 RGB LEDs strip on Adafruit, and I've read this: The bad news is that the HL1606 doesn't have PWM which means you can only set the LEDs on or off
    I am working on how to get a strip of 60 leds to generate a pattern or how to get at least a running light with 8 on leds. So I have two questions a) Can they it be done without the help of Arduino or a Microprocessor, if so how? b) If it cannot be done, can some one help me with the microprocessors. Thank you
    Hi all, I'd like to create a touch sensitive LED strip, a bit like this - http://www.lutron.com/Products/StandAloneControls/Dimmers-Switches/ViertiDimmer/Pages/Overview.aspx . Touching the LED strip makes the LEDs light up from the bottom to meet your finger. The LED strip is obviously easy to handle, but I'm not sure of the best way to detect the touch. I can't seem to find any transparent touch strips, an iPhone digitizer is transparent but way too big. Does anyone know if there's something similar to the iPhone digitizer but in a strip? or any other ideas on how ...
    Hi there, I am currently working on a little project where I want to controll this RGB LED strip with my arduino. Since this is contains rgb leds it would be a shame not to use pwm to get out all the nice colours and get it to crossfade in and out. The strip however runs on 12 volts so how would I go about using the arduino with it's analogWrite() function to controll this?. I have done some electronics in the past but latly the only thing have been working on that is remotly similar is computer hardware. From what understand ...
    I've been experimenting with the RGB LED strip and found some problems and need some advice Using 24 LEDs, Arduino Pro 8Mhz, 3.3V. using pins 10L, 13CLK, 11DI, SI not connected using basicPatterns (and lib) for non PWM control I'm connecting the ground pin on my arduino to the ground on the power supply for the LEDs, is this correct? Generally, I get random LEDs lighting up and then they just stay that way. However, if I remove the ground pin (the one near pin 13) all LEDs turn white and stay that way, until I put the ground back in, at which point ...
