ESP8266 Community Forum

- Mon Jul 11, 2016 3:36 am #50560 I have been trying for days to dim a light bulb using a ticker timer available for ESP8266 but no luck yet. I have even edited my timer library to support microseconds but bulb doesn't dim properly as it FLICKERS!
ESP8266 also resets, this may be due to timer mismatch or any similar cause.
Also, while dimming the light at 60% and above the light dims, after some time it starts to flicker and eventually the esp resets.
If anyone has tried the same project and suffered or solved the same problem ,please suggest me how to fix it!
I am uploading my code where I have used Ticker library to dim a light bulb so you can understand my problem.

I'm presuming you're doing incandescent bulb dimming? What does your schematic look like?

you would have found:
viewtopic.php?f=28&t=8745&hilit=zero+crossing or
viewtopic.php?f=45&t=9907&p=47139&hilit=zero+crossing or
viewtopic.php?f=19&t=5847&p=30784&hilit=zero+crossing

and maybe a solution:
