Addressable RGB LED Strips from Sparkfun
Hello this is my first post so I hope I’ve come to the right place.
I have purchased 8 Addressable RGB LED Strips from Sparkfunhttp://www.sparkfun.com/products/10312 and they are a blast! I have connected them in a chain from 0-255 and wrapped them around to make a matrix. I only use 2 pins to send the data and every second strip has a 5V 3A supply and a common ground connected to the Arduino.
0, 1, 2, —gt— 29, 30, 31 STRIP #1
63, 62, 61, —lt— 34, 33, 32 STRIP #2
64, 65, 66, —gt— 93, 94, 95 STRIP #3
127,126,125,—lt— 98, 97, 96 STRIP #4
… STRIP #5
… STRIP #6
… STRIP #7
… STRIP #8
……. you get the pointI am able to control them without any issues and the brightness is impressive. The next idea I have is to use this 32×8 “matrix” and make a stock market like text ticker. I can write text now but it is a very tedious process. I turn on each LED individually then post the frame to get the text I want.
Does anyone know a simple way to convert text into a matrix so that I can display it on my strips?
Is there a SMART approach to this problem?
Is there a library that could help me out?
Would using MATLAB help?
Anything that could point me in the right direction?

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 ...I am a complete beginner at arduino and electronics in general, but I'm trying to make an LED strip do a simple chase sequence. The LED strip I got is just labelled with ZJ168, which seems pretty uncommon, so I haven't found any basic instructions anywhere. I connected the strip as described here: http://frabjousdei.net/post/2773451294/ive-finally-got-the-rgb-led-strips-i-bought-from, and tried running the FastSPI_LED library example, but all the LEDs just light up at once and don't change. I'm probably doing something very basic wrong, but I've done many searches and can't seem to find any basic tutorials or anything for this kind of strip. I'd appreciate ...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.htmlLets share our addressable RGB strip routines. Here is the code I use to throw out a led and have it bounce back Code: Select all void bounceSingle(uint8_t color, uint8_t wait) { uint8_t i; // turn everything off for (i=0; ilt strip.numLEDs(); i++) { strip.setLEDcolor(i, BLACK); } for (i=0; i lt strip.numLEDs(); i++) { strip.setLEDcolor(i, color); if (i != 0) { // make the LED right before this one OFF strip.setLEDcolor(i-1, BLACK); ...I purchased a FlexTech addressable RGB LED Strip from Home Depot and would like to hack it using my Arduino. The controller/driver chip on the strip itself is a Power Mos P9816. I cannot seem to find out too much information about it and the datasheets are all in Chinese. It seems pretty standard with just 4 pins: +5v Data Clock Gnd Is anyone familiar with this chip and if any of the existing RGB Strip libraries might work with it? Thank you!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.

I am very stuck on a problem and would greatly appreciate your kind help, please! I thought I was careful and very specific when purchasing this 5m strip of water-resistant, addressable LEDs: I wanted to be able to program these from an Arduino. I should have demanded to see it programmed in store. I was told it's exactly the same as the Adafruit 8806 strips (http://www.adafruit.com/products/306). I find that neither of the Adafruit tutorials matches what I have in front of me and I'm really concerned that I'll hook it up wrong and either fry ...Originally, I sent this in as an order problem and was told to take it to the forums, so: I recently received my second order for 2m of the RGB addressable strip. 1/4 of my 2m strip (0.5m) will not respond to PWM code with the SPI divider set to anything below 64; whereas the other 3/4 of the 2m runs perfectly with the setting at 32 (or even 16, for that matter). The code on your website mentions that some of the strips do not like the SPI divider set below 32. So, while I understand that a strip may ...I recently bought several meters of both the Digital RGB LED waterproof flexi-strip (ID: 306) and RGB LED waterproof flexi-strip - (ID: 285). These come with some nice connectors attached with ribbon wire. Each Strip has a male and a female, so I can cut one end off and attach it to a controller/power supply. However, I'd like to cut up the strips into smaller pieces. That will leave me without connectors for most of them. I can (and in some cases will) directly solder to the strips but I like the Adafruit connectors and would like to get more. ...Hi I've managed to compile samba for arm. Just one tiny Big problem left. How do I strip those big binaries? I can't use arm-elf-strip because it's elf2flt'ed. I can't strip all the object files before linking. (you can't link without symbols.) How do I strip an flt binary file? Or how do I intervene (strip it) before elf gets flt'ed? Thanks export CC=arm-elf-gcc export CFLAGS="-Wall -O2 -fomit-frame-pointer" export LD=arm-elf-gcc export LDFLAGS="-Wl,-elf2flt=\"-s32768\"" ./configure --target=arm-elfHi, 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 ...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.jpgHello, We are a band and have a project for a new light show. We would like to control digital RGB led strip using midi notes coming from ableton Live on a computer. Is it possible to control an arduino board in midi and control the strips? For example one MIDI note = one color at one position so if I program a Midi melody on ableton I'll have a LED sequence on the strip. If yes, how many strips will I be able to control with one arduino? Another way could be to address the strips with DMX and a ...I have two led strips that I want to control using an Arduino Uno. I want each one to be doing something different and not both of them doing the same thing. How can I accomplish this? The only way i see to control the strip is to write to the strip. If I have part of the program controlling one strip, how can I have it sending commands to another pin in a separate section. For example, I want to write to pin 9 and pin 10 at the same time but they would be doing something different. for ...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 I tried recently to get one of these http://www.bliptronics.com/item.aspx?ItemID=128 led strips working with an arduino. Had no joy, having followed the instructions using sample code on that page, and http://www.sparkfun.com/datasheets/Components/LED/LED_Strip_Example.pde. All that happens is the first led in the strip flashes, and only when the ground from the 5v supply is not linked to arduino ground. At the same time I got some of these http://www.bliptronics.com/item.aspx?ItemID=110 which use the LPD6803 and they worked fine with the sample code provided. Since then I got a strip similar to this http://www.adafruit.com/products/322 along with a controller someone had made using an mbed ...I would like to read linear distance measurement from my digital caliper. Caliper itself has a simple connector, that has 4 contacts. Just 4 plain strips on the PCB. I found some photos here that explain more: http://www.steves-workshop.co.uk/tools/milldro/milldro.htm strip 1 is: -V strip 2 is: data strip 3 is: clock (What is the use for clock?) strip 4 is: +V What interface would this be and how is it operated?I've found tons of information on connecting RGB strips but none of them have as many pins as the ones I acquired last year. I ordered 4 of these from China last year...took 4 months to get them. Anyway, here is the exact same strip. http://www.goodluckbuy.com/5m-rgb-led-flexible-strip-light-lamp-w-10-pin-m-f-connector--remote-control-box.html?ampsl=en The 10-pin connector is confusing me. I'm not quite sure what pins do what and how to connect them to a controller. I saw someone had done this on YouTube with this particular strip but he hasn't responded on how he did it. He did mention that is a common HL1606 controller., but those, from what I've ...I'm getting the error 'Color' was not declared in this scope on the code below with c = Color(255,0,0); being highlighted. I'm trying to get the LPD8806 LED strips to run a color pattern from the center and I'm missing something that's preventing the code to compile.
