I have a NO sensor hooked up to my garage door. For some reason the particle.publish won’t send the message of the door being open. I am sure I did something stupid, so if anyone can pick it out I would appreciate it. Here is the code. I have the power hooked up to the 3v output. int doordetec…

Normally if you’re reading a switch, you would use digitalRead, not analogRead, although that could work if you have things wired up correctly (a wiring diagram would be helpful). You should put in a Serial.print() statement after the first line in loop() to see what value you’re getting from your a…

@jzalar , the issue is most likely due to the floating analog input which can read any random value depending on the electrical charge on the pin when you read it. I would follow @Ric ’s advice and treat the pin as a digital input and add an external pull-up or pull-down resistor depending on how you…

I will order some resisters today. I will let you guys know how it works after.

Good News and Bad news. First the good. The resister did the trick and keep the analog reading down close to zero. This also helped with my problem on the home alarm system. I keep getting multiple notifications from IFTTT. Related Post here Particle.Function () losing its value Now the bad ne…

There’s nothing wrong with your bool, the code works fine for me. If you can, you should put in some print statements (as I said in my last post) to check what values you’re analog read is giving you. Also, check your console to see if you’re getting a publish event happening every second to rule ou…

Yes, there is an problem in the code - although maybe not the only one :wink: [image] jzalar: if (analogRead(doordetector) >=3900 && dooropened != true) { dooropened = true; ... } else if (analogRead(doordetector) <=3900) { dooropened = false; } if the…

Thanks for the feedback. I am using a simple magnetic door sensor mounted on the garage door and wall. I agree that the multiple analogRead need to be removed. I will also try rewriting this with a digitalRead too. I am traveling this week, so it will have to wait until this weekend. Here is wh…

Well. It seems to be working. I might be updating my home alarm code with digitalRead this weekend. int doordetector = A2; int button = D4; int doorvalue; int hour; int out = A5; bool dooropened = false; bool after9 = false; void setup() { Time.zone(-4); pinMode(out, OUTPUT); pinMode (doordetec…

@jzalar, depending on the length of your sensor wires, I would use 2.2K, 4.7K or 10K ohm resistors.
