I’ve been spending a little time writing a Larson Scanner for my 15 pixel light strips (cheesy I know, but it’s not your average KITT, it has color scrolling and also a nice fadeout to simulate incadescent lights).
Tonight I’ve moved it to a 60 LED WS2812B strip, one line of code changed and it’s up and running. Now I’m playing with memmove to replicate patterns along the strip, and I’ve written a reflect routine to do some mirror copying too.
Next I’m going to start to play with some additional hardware to control speed and colors, the fun just goes on!
I’d just like to repeat my thanks to Daniel and Mark for an awesome library, and to all in this community for the inspiration, hints and tips and help.
Amen! Their hard work makes amazing stuff strikingly simple!
Don’t forget to post videos of your progress!
Will do - I’ve been having a bit of trouble with video though, seems that whatever settings I try, the video ends up with the colors washed out, and the video of the LEDs never looks quite as good as they do in real life. Any tips for camera settings/lighting to get the best results would be gratefully received 
The only way I can a “decent” looking vid of my LEDs in to set the master brightness to around 64 or 128
I tend to shoot at full brightness so I don’t lose some of the lower values, but I adjust the camera, closing the aperture, adjusting exposure, etc., etc. …
I will have to have a play with my SLR, I’ve been trying with my camcorder but it just doesn’t give me enough control. Might try using my smartphone too, it copes with difficult lighting well.
