So if i'm understanding correctly - since I have a single RGB LED strip, the number of channels in boblight.conf should be 3 and it should use channels 1,2 and 3 no?

I tried setting it with 6 channels and using 4,5 and 6 as well as 3 channels using 1,2 and 3 but no luck so far.

if your problem is software related and if you aren´t experienced with electronics I´d suggest to use some ULN2003A, then you do not have to solder that much.

Actually I'm an electrical engineer - so I'm not really worried about the electronics - and in fact I'm already using a ULN2003A - it makes it that much easier to put everything together on a veroboard.

For the time being however I've hooked up a single RGB LED directly to pins 9,10 and 11 of the Arduino to eliminate any possible points of failure until I get everything working.

which software did you take for your arduino?
enabling debug mode in boblight.conf could also help to see what´s going on...

i´m tryin to run boblightd on my fritzbox router now with freetz installed.
if i run it with a config file which works on ubuntu it says that it cannot find any devices, colors and lights... any ideas?
here´s the output. using r 417.
could it have to do with the filesystem (squashfs) the router is using?

Code:

root@fritz:/var/tmp/boblight# boblightd

and here´s some info about the compiled binaries.

25 leds are 75 channels, 50 leds are 150 channels and so on
how many leds do You have on that strip?

no, wrong. three channels for one strip, not for one led.

No, not wrong. RGB -> Red, Green and Blue. 3 channels for one LED. So 50 LED's are 150 channels. Not that difficult.

Believe me. LED strips are several RGB leds arranged in paralle (--> they all send out the same coulours all the time)l, so you only need 3 channels for one strip with several leds.

Sorry, you're right. I thought you were referring to the channels in the boblight.conf. Confused
