The LED Strip Driver with 4-pin Grove interface provides easy connectivity to your standard Arduino device or Seeed Stalker. It can help you control the luminance of a single-color LED strip, as well as the color and the luminance of an RGB LED strip thro
I have loaded the SingleLEDstrip.ino sketch but I cant figure out how to make the colors fade smoothly. The example just shows quick color change. Is there a way to make the colors fade into the next?
yes, it is possible. Led color is controlled by function Driver.SetColor(char R,char G,char B) with gray level 0-255, you could modify the gray level to make color fade smoothly, for example,Driver.SetColor(255, 0, 0) set Led color red brightest, Drive
I have 9 Led of 20W 32v each one (http://dx.com/p/20w-2800-3250k.... Can I use this grove to manage it?, can you suggest to me ano
Hi Adrián Rivelli.This driver may not manage it.And we have no driver could provide 32v to your LED.
I need to chain the LED more then 96 LED stripis it possible to chain more 96 drives? Can these drivers control by one arduino?
Hi,you can chain many LED strips together.And you can control them simultaneously by one Arduino.
I'm just curious. Why there are no mounting holes on this module? Is it possible to mount it somehow to the Starter Bundle Harness?
Thanks. I understand the connection to the board and programming but I'm not sure if it is possible to attach this module to the Starter Bundle Harness with screws.
I have the led driver and wasn't aware that I needed the base shield for use. Am I able to connect this driver to my arduino without the use of the base shield?
Hi,you can connect this driver to your Arduino directly.CLK--_digital 2.DIO--_digital 3.
I'm confused by the specification table at http://www.seeedstudio.com/wik...
My case is that we're going to connect three different color LED strip
it means if this module connects 5A@12V power supply, the driver current can be upto 3000 mA when the lED Strip is 5m, 3000mA presents the total three channel. for your application, you will connect the three different color LED strips onto 3 LED s
I am interested in driving 5-7 meters of RGB LEDs (fortunately not all will be on at once). I want to be able to control the ramp on and off times of the LEDs, to be able to turn on individual leds in a random order (eg random controlling a range of 9
Hi.You can refer to this link(http://www.seeedstudio.com/for... and just have a try.
it is possible to wried to raspberry pi gpiowhich pinand and sample code?
Hi James Kong.If you use gpio with LED strip Driver directly,you need make a library for it youself.But if you plug a Alamode on Raspberry pi,you can use the same pin and code.
If you rotated the "out" grove 4-pin harness 180 degrees, the cable to the next one in line wouldn't have a hard-to-manage twist in it...
Never mind, I found it. Can I send you my Gerbers so you can verify them before placing my order? Thanks.
If I wish to connect 4 different LED stripes (each LED strip is composed from 3 different colors LEDs connect together, each color LED is 10cm long). Therefore, is it possible and do I need 4 LED Strip Driver? Will I have some power proble
Yes , you need 4 led strip drivers. The numbers of driver you can use are depended on the total load of your circuit. And if you wanna run the same blink code to work with all the stripes in parallel, you can modify the code from wiki: Driver.begin();
Can you please describe all the components used to build, "In case of two LED strips, upload the DualLEDStrip demo code instead" section in this URL:http://
Two led strip drivers , 9~12v power supply for both two led strip drivers , two led strips , two grove cables , one Seeeduino , one Base shield.
can you tell me the dimensions and holes please.Or even better would be a sketch where I can see it.
many thanks and excuse my english
The diameter of those four holes is 2.2mm.And more information you can refer to the PCB eagle of this product.
Hi there, Yes, Of course you can use 2 drivers. Please keep in mind that It can drive an LED strip 1 to 2 meters long with 9 V, while 1 to 5 meters long with 12 V. thanks.
