solution for getting LED rhythmic fluctuations

[davidm]

for my DIY LEDs I found this function generator from Amazon. With a 18V DC power supply I had lying around, this function generator alternates at 1 Hz(once per second) a sine (or triangle) wave from ~7 V to ~10V DC to give some oscillations / fluctuations to my LED bank. I'm only using it for every 1 out of 3 LEDs, and it gives some nice rhythmic oscillations in LED output. Sorta like fast moving cloud cover. just thought I'd share.
