Pulse brightness up and down? #39

I see the overall strip brightness is set as one-time variable.

LED_BRIGHTNESS = 255 # Set to 0 for darkest and 255 for brightest

Can I use a function like 'rainbowCycle' and have it run through brightness from 0 to 255 over an interval and reverse and repeat? Possible?

Yep I'm pretty sure you can - in library/rpi_ws281x/rpi_ws281x.py, there is a PixelStrip class method called setBrightness() that will allow you to modify the brightness of the LED strip.
