I am working on a thermostat type project - It is working fine but I want to add a few safety aspects now. I notice that if I disconnect one of the thermistors then the the arduino sees that its too cold and will keep on heating.
If I disconnect the thermistor and look at the value of the reading, it returns ‘nan’ - this is not a problem but is there a way to say ‘if (reading == nan)… do something’
I will post the code but I do apologize, its a mess!
