I'm green wanted to make this project

[greenjames]

Hello this is the first time I've posted a question on this site.

I wanted to build a project with my 12 y son this summer I'm very new and green to electronics so I thought I would start with a led banner
just like this one off youtube [url]https://www.youtube.com/watch?v=sbdvrfwr6Sg[/URL]
so as normal I jumped in and started ordering parts for the project as I have banner material sitting in the garage (well outside) Black and white PVC.

as normal I ran off and ordered some led strips RGB AND STARTED RUBBING my hands together and patting myself on the back, now here's the kicker I think I've ordered the wrong strips.

I maybe wrong but the strips I ordered from ebay are these one **broken link removed**

I thought I was ordering RGB leds but they are not !! They are just solid RED GREEN AND BLUE LED'S or am i wrong. is it just the controller that can't mix the colour of each individual led, I under stand it's three separated dice that change the colour of the led.

I need help with this what can I do with the LED'S I've bought ???

it looks to me as though the LED strip is a bit of flexible cable with R,G,B leds on it. If you looks at the plug that goes from it to the controller it has 4 pins, Lives for RGB and an earth return.
what the controller does by remote control is to pulse the various coloured LEDs on and off to give the impression of different colours. So extreme example, RGB all on for 1/3 of the time = white. Turning up the red time from .33 to .5, will turn the white "pink".
So what you have to do is to figure out what voltage and current the LEDs are running at, then you can split the flexible ribbon and feed your own voltage in to give a different effect.

The explanation by chuckey is pretty plausible. If the three LED-chips are all inside one component, as one tri-color LED component, the "mixing" should work very well. However, I am afraid, that the differently colored LEDs might be physically separated by some distance, and therefore the result wouldn't be white, but three separate colored "dots".

GreenJames: You should be able to check that, as you have the strips.
