Hi all,
I have a dehydrator that only has a heating element at the bottom. It is vented so there is airflow via convection but not enough for my liking. I currently have an ATMega328 board not doing anything and I have never actually done an arduino project before. I would like to add some fans to the top cover and place a temp/humidity sensor up there with them. I was hoping to connect a POT to the arduino to control the fan speed and possibly connect an LCD to display the temp and humidity stats. I did find the DHT11 sensor for the temp/humidity but I am not sure it would work. I have extremely minimal programming experience *don't feel I can count powershell scripting
Any advise on this project or even a project similar to this that I may have overlooked would be greatly appreciated!
Excellent thank you! I will keep that for later reference. For now I want to get my fan hooked up to my arduino. I have a 4-wire PC fan I'd like to use. This would be a 12v DC fan with the green Tach wire and blue PWM. I'm pretty sure I understand the wiring, for now I do not have an LCD to use so I'd like to simply get down and understand controlling the fan speed with a POT and the arduino. This is where I get a bit confused, if possible I'd like the arduino to pass through the grnd to the fan only when the arduino is powered on so that its power essentially controls whether or not the fan is powered. I'll start going through the tutorials but any help would be greatly appreciated, thanks guys!
