@davee The "port" part of the IDE > Tools is disabled. Apparently this is a common issue, and because there are hundreds of boards, there are thous...

UPDATE: Looking at it some more it looks like it does compile without an issue. It is at upload time when it not only starts compiling again, but th...

In the sketch I am only trying to trigger "something". It doesn't matter for now if the numbers are realistic. They will get so once I have the schema...

It certainly helps, thanks a lot. I will give it a try. Farzad

So, this circuit in principal works. When calibrated relative humidity as simulated by a simple potentiometer is pushed to a certain percentage, and a...

It turned out it wasn't the resistors but the equation I used for the pulse to the MOSFET's gate. I have adjusted the equation, taken out the extra te...

Here is the full picture. I read the article, thanks. I have tried lowering the resistance of those resistors and it still doesn't work. I think som...

@will Is this what you mean: After including the resistors the light cannot come on anymore. But that is fine because I need to calibrate the pote...

@robotbuilder I will keep practicing. Thank you for the feedback. Farzad

Of course the relationship between analogValue and analogWrite to the mosfet is not linear and has to be determined more thoughtfully, for example wit...

@will good idea. I can take a few TMP36 sensors and spread them around the front element retainer of my scope, hook them up in parallel, take the aver...

@will Once the dew point [temperature] (DPT) is calculated using the reported temperature (T) and relative humidity, then the delta between the DPT an...
