  • specifications

    posted by rickneal

    Im looking for the specifications on these bricks. Im using 13 of them plus motor speed sensors and I need to know how much current im pulling? The specs only show their size? Where do we go to get the information we need on your products? To aid in calculating current drain?Im sure im not the only one who wants to know.Thank youRick
    I like the discount rates.
    The price is good and I like the design, but need specs.
  • Very bright quality RGB LED light

    - Nice and compact.- Nice build quality.- Very bright.- Easy to connect and to work with.- Works nicely with PWM control.
    There are no resistors mounted on the board. They are not needed of you are working with microprocessors like the Arduino. They work directly on the PWM output pins of the Arduino (3,3V). At 3,3V the LEDs are very bright, and get warm, but extremes are not exceeded.
    For testing this module with an Arduino, follow this tutorial here: http://www.arduino.cc/en/Tutorial/ColorCrossfader
  • Beware - it is common ANODE!

    It works. Bright enough, quality is good. Price is right
    I've used four shift registers (one controlling anodes via mosfets, three others directly controlling R,G and B cathodes).
    I should have got four of those to make a large sign/display unit.

    Bright RGB LEDsSimple hookupUser can control two pairs of LEDsFor Arduino use ShiftPWM library
    I was able to make this module work with Arduino using the ShiftPWM library from Elco Jacobs at http://www.elcojacobs.com/using-shiftpwm-to-control-rgb-leds-with-arduino/ . I only had one but I assume that the library will support daisy-chained modules. You will also need a robust 5v power supply, since the Arduino digital outputs don't have the required current to drive the module.
    If you don't mind experimenting a little, I think that this module is good value for the money.
