So I am stuck on this one. I have some led lights that I am trying to get to work. I have two strips that are connected to a NodeMCU (one on pin 5 and one on pin 6) I want to be able to control them separately. I am trying to control them using MQTT. I used BRUH Automation’s code for the most part and it works if I don’t seperate them out to two pins. I have since added a second set of topics and modified my code to include a second pin. I have tried lots of things and now have gone back to removing most of the code to see if I could find the problem. What I came across is that if I include the following code in my arduino then I can no longer turn the leds on or off for either pin:
client.subscribe(setcolorsub2);
I comment this out it seems to work.
Here is the rest of my code if that helps. I am just stuck and probably missing something simple.
