zero values

[spfmoby]

I'm a beginner with arduino stuff, but when I try your "part1" script, One thing I noticed is that you can't turn off the light if you set a zero ('0') value. It is possible to replace ">0" by ">=0" in the main loop(), it works, but then it is impossible to set the light back on. What Am I missing ?

Thanks in advance

What type of relay are you using? I see issues with active low 5v relays.

-Thanks

I use the Robotdyn 2 channels dimmer https://robotdyn.com/ac-light-dimmer-module-2-channel-3-3v-5v-logic-ac-50-60hz-220v-110v.html everything is working properly (values between 1 and 255).

No other relay

I had to do the following in the main loop :

      if (val>=0){
        tarBrightness =val;
        Serial.println(tarBrightness);
      }
      if (val>0 && state == 0){
        state = 1;
      }

Had the same issue. I was using a similar dimmer circuit of my on with the esp8266-12e. The light cant be turn back if we set targBrightness to 0 at some point. As @spfmoby suggested, the trick worked for me. But I'm not using it in the main loop. Using like this void setBrightness1(int val) { tarBrightness = val; if (val>0 && state == 0) { state = 1; } }
