Friends, I have wired up a float switch and am trying to get it to work with particle publish. I’ve learned thus far that you shouldn’t publish from the interrupt directly because it freezes when the interrupt is tripped, but am having trouble on the software side of things. I have the interrupt s…

Let’s say it triggers, and h == 1 now. Seeing as you never change that value, it will stay 1 and trigger on every iteration of the loop. The code is working as it should, just not as you’d like it :wink: If you use that laststate variable, you should be able to make it work. In the IF, check for th…

Thanks Moors7, this is what i was trying to accomplish initially but got a little confused along the way. I tried what you recommended and it worked! here is the new if statement that is in the loop, for other ho may be having the same problem. if(h==1){ if(laststate!=h){ lastst…

You could ‘shorten’ it a bit, since the 'laststate != h` needs to be true for both cases, you could use that to encapsulate the lot. if(laststate!=h){ if(h==1){ Particle.publish("TopFloat","FlowingUP"); } else if(h==0){ Particle.publish("TopFloat","FlowingDOWN"); } …
