    Firework Control Module

    ha ok I see what you mean :) I changed the resistor to 1k and one leg is in the hole the other on the sensing wire (not in hole)... works good! I also ordered some of your optocouplers, since i blew up some of mine haha :)I also understand what you meant by series and parallel.. the rail was still full power since the sensing wire was using it instead of the resistor. if it wasnt a rail I would of been fine :)Thanks for all your help. much appreciated

    Firework Control Module

    Thanks Jon for helping me out with this. I got further. What I didnt have was the dummy led part of the circuit. I guess that completed the circuit. If I connect the wire to the Negative side of the speaker terminal, the LED lights up (also the LED in the terminal. I inserted a led with resistor in the terminal to create continuity for testing). I have noticed that the led will light up (dummy) as well if I connect to the positive terminal (its direct to battery so I guess that makes sense :) and in this case the led in the terminal doesnt light up so definitely need to use the negative terminal for continuity testing).With all that being said, my optocoupler still report HIGH. I am using the TIL193. Maybe its not a good one for this job? I am a total beginner with arduino and electr...

I am using the TIL193. Maybe its not a good one for this job? I am a total beginner with arduino and electronics in general and datasheet for me are still just... stuff :)I have attached the datasheet and couple images to show you my circuit (some closeups)I think my only issue is with optocoupler now. I added the white dot to show you where the dot is on the chip (very hard to see). My first guess was maybe i didnt connect it on right side...flipping the switch didnt change anything... Maybe you know lots more about this than me :)

    Nice thanks for your answer. It would explain alot. I just compared both datasheet and on mine the anode/cathode are always same side.. on your it alternates. regardless, maybe ill end up getting the same ones as you :).I am not sure what you mean by series or parallel. I seem to have connected it exactly the same way you did. resistor at chip pin and to sensing wire. direct connection

    thank for answering after all this tine :). Well looking at your original diagram, i seem to have it correct. I am using a 10k going to the 5v side and using a 1k going to the node (wasnt sure if that was correct but i follow the colored rings from your design). the speaker terminal has ground connected to 12v side and positive side to the relay for when it activates. so on the firing node side:Optocoupler 1st pin - - > 1k - - > positive side of the speaker terminalOptocoupler 2nd pin - - > Ground of 12v side {or should i connect it to terminal negative side instead? dont think that would change anything} on arduino side:Optocoupler 1st pin - - > ground to 5v from arduinoOptocoupler 2nd pin - - > pin to D5 - - > 10k - - > 5v from arduinofor some reason, having th...
