    Not much, I will clean it again. I really hope this is the solution.

    Do they stay on when you remove the MOC? If so then you have a short someplace. If not then you are not driving the MOC properly.


    2019 - Just moved into a new home (yet another change of plans). Will be dim but not dark. Too much to do at the new place to leave time for a show.

    That is an excellent debugging tip !

    Before I take the chip out, I connected a mechanical relay to it. Shouldn't that have worked? It seems the outputs just can't trigger anything besides an led. EDIT (NVM The mechanical ones work.)

    They do not stay on. I uploaded a simple on-off sketch and it seems to work fine. So it must be something with code?

    I used this to test it:
    Code:
    void setup() {
      // put your setup code here, to run once:
    pinMode(24, OUTPUT);
    }
    
    void loop() {
      // put your main code here, to run repeatedly:
      digitalWrite(24,HIGH);
      delay(500);
      digitalWrite(24,LOW);
      delay(500);
    }

    ok. That means we are looking at a software issue. You do know that most SSRs are active low. That means the lights come on when you send "LOW" to the output. Check your controller code to make sure "ON" == "LOW"

    Check the voltage of your output pin when it's low. My guess is that it's not really "off." Arduinos can sometimes float down around 1vdc when "low" and that could be enough to keep the MOC's internal LED lit.

    If that's the case, try increasing the value of the MOC's resistor on the SSR. It's probably a 680. Increase it to 1K and see if that helps.

    I GOT IT! I switched zparticles code to be the opposite. I knew I had to do this but I did not know that it would affect everything since I just wanted to test the dimming... I knew the lights would be opposite but somewhere in the code, it prevented that. Lesson learned is don't wait for the end to fix a problem you know how to fix. lol

    It's all good!

    Ok have to ask because I am using arduinos and sainsmart 8 channel ssr,s wich are zero cross I believe and would like to get the dimming function at some point . Iím new to the hobby and still learning some of this language?
