  • 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.
  • 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.
  • Bright RGB LED

    posted by GeeJiiZet

    It's bright and all three LEDs in it can be controlled separately. For example when using Arduino, it can be directly powered from the PWM pins with no extra components. The diodes also start emitting at quite low voltages, so there is good range for adjusting the brightness of each channel.
    The module has pins labeled wrong. The ground pin (-) is correct, but the color channels are not in RGB order, but BRG. Easy enough to find out by testing. Also since the LEDs are separated from each other, you might want some diffusing element to mix the lights together.
    Want fancy color lights in your DIY project? Here you have it.
