Not sure if this is the appropriate place for this question but, here goes.
I'm controlling 12V LEDs with an esp8266 using PWM and MOSFETs. It works as intended except when the lights are dim I get flicker. I tried adding an electrolytic capacitor which helped a little but still flickers, maybe a larger one?
How can I prevent the flickering?
If you are using PWM, adding a capacitor will negate the PWM.
is could be a symptom of the LED's blinking and the ambient light resonating.
Try it in direct sunlight and not artificial light and see if they still flicker.
(or use a DC light bulb to illuminate the scene)
