OK here is the latest program for the fan speed control.  It also has provision for a servo to open or close a vent door, if needed.

It's saved as a TXT file. You'll have to open a new Arduino "sketch", and paste in the file.  You may also have to download the libraries.  Modify as necessary.

Thanks for doing this Willie. I know the parts have been detailed in previous posts but if you can put a final parts list in one post it would be great.

I'll work on that. I only discovered yesterday how to attach a file. Need to update the wiring diagram too.

However I DO NOT recommend trying this unless you are already familiar with the Arduino. If not, get a beginner's kit (I did) and make some simple projects first.

That is about the extent of my experience. Lots of dancing LEDs but nothing practical.

That's how mine started out, too, but it quickly got into motor control, servo control, etc. YOU have to figure out the practical applications, though Google can be a lot of help.

OK the wiring diagram and parts list are added to post #41, I saw no reason to reload them again.  I'm not the best at wiring diagrams but I think you can make sense of it.  I didn't get all the parts from Ebay, but you can.  Might do better at a local electronics or hobby store.  Good luck!

stmbtwle,
Your program and parts list is great! I am working on a full monitoring system for my collector plus a second project to track and measure dawn to dusk light intensities using different materials and their effectiveness at various angles.
I would like to see your completed program. You-tube has a wide variety DIY videos on just about any component you can think of.
