Haha, good point. I believe the ESP8266 default PWM frequency (via the Arduino library) is 1KHz, which is well above the ranges cited in the Wikipedia article for flicker fusion threshold across animal species. In my very limited testing, my fish didn't flee under plants as readily when the lights turned on more gently. https://en.wikipedia.org/wiki/Flicker_fusion_threshold |
