I will try to post mostly about arduino high power led shield and discuss related topic such as general high power leds, i2c communication on arduino so on.

    How soon can you ship the high power arduino shield? We would need it fairly soon, Detroit area. Also what would the shipping cost be?

    Thanks,
    Nick

    Hello, i’m looking for something similar to this, however not sure if this is exactly what i’m needing. what i want to do, is have 5 strings of leds, each string having a different color led. but i wont to be able to control each strings dimming separately, if i read correctly your led shield can control 3 string? would i be able to do this with 2 of these shields?

    Thanks!

      The shield is designed for High power LED not for LED string. You can use MOSFETs to dim the LED string. It can be easily done with PWM from a microcontroller.

        I’m also interested in powering some LED strings and dimming them with an Arduino. What are the steps needed hardware-wise? Do you have a link to another shield or a instructions for doing the connection?

    hello,
    i received a couple of boards and they work perfectly.
    now i discovered that when using goToHSB command, hue has only about 6 steps from 0 – 255?!
    am i missing something or can anyone reproduce this?
    thank you

      well i guess thisis the way hsb colours are set…
      - choose 1 of 6 basic colours and then mix in saturation and brightness

        Yeah, from the code I can tell that some precision is lost in the integer arithmetic they perform. I used my own HSB-to-RGB conversion code that uses floating point and it worked for me.

      There is some precision lost during conversion. I will take a look whether I can improve it.

    I would like to stack the Arduino, two of the v2.0 LED shields, and another shield, and power everything with one 36V 3A input. Each LED shield will provide 350mA ~30V per channel.

    Is there anything special I need to do to do a proper connection? Do I just stack them in any order and connect power to one of the two LED shields?

    Also, I don’t completely understand how to assign IDs. Can a shield have two different Device IDs? Why does the manual say that there are two I2C chips? How do you specify which device you want to control when using the library?

    Hello, I would like to make a purchase, but my shipping and (mailing?) or do you mean billing? address is different and too long for your form. Please advise.
    Thanks,

    I would like to ask you some questions about high power led circuits. Can you contact me via e-mail.

    Thanks in advance.

    Is it possible to individually address the pins? My thought is to be able to change the value of the outputs separately so that when R & B & G are at 240, I can set G to 210 and then change B to 180 without rewriting R both times – as I would like to set the value of R with random(120)+135 (and also be able to set B & G the same way)…

      I will update the library for individual channel address later.

    I recently purchased a high power LED dimmer from another supplier and the LED flash momentarily to full output power after each change of dimming intensity. This is not acceptable for my application. Is that a problem that could happen with this shield too? If yes, under which conditions, and what can be done to prevent it?

      I don’t know why you are seeing such a problem. I have not seen the problem with the shield with various condition that I tested. I have not heard similar problem from people who purchased the shield.

    Hi, I’m interested in buying the high power arduino shield – ‘pins + shield + temp sensors’, I live in Italy, how much?

    I am interested in your shield for a couple of art projects, what is the current availability? If I need 7 lights going on at different times I would need 7 shields?

    thanks,

    fredi

    I recently ran across your high power RGB LED shield while researching things prior to desigining something very similar for a project of my own. Your shield looks almost ideal for what I need, except I would like to adjust the design to be smaller (not a shield) and more specifically suited to my application.
    I was wondering if you would be willing to discuss, over email, what changes would be necessary to most efficiently drive RGB LEDs with 2.8v/4.0v/4.0v channels, from a 5.0v supply?

    Just wondering if this project is still active. The software was last updated around October 2011

    hello
    i would like to use this shield on a RGB emitter i ordered, but it’s stronger then your specs.

    http://www.aliexpress.com/item/1pc-100W-RGB-High-Power-bright-Led-Red-Green-Blue-Energy-Saving-100Watt-Lamp/667356269.html

    Will your shield work well with my emitter?
    Which power supply will i need for my emitter?
    thanks!

    Do you have HPL (high power leds) dimmer for aquarium ?
    can set cloud of color with timer. (day and nigh)
