Hi, first post here.
I don't yet have an arduino board or parts but was thinking of buying a starter kit alternatively only the parts needed for the project below.
I understand basic programming concepts but not that much about electricity.
However, I like to learn by doing things.
The purpose of this post is primarily to get help choosing a suitable arduino board as well as suitable components for the project below. No need to advice me on the programming part yet, the plan is to learn to use and program when I get the components.
What I have:
-a 3D-printer with a custom built enclosure (to prevent drafts and increase ambient temperature).
-a 12V PWM computer fan to be mounted through the back wall. (NF-F12 industrialPPC-2000 PWM)
What I want to do:
-read the temp inside the enclosure
-increase the fan speed proportional to the temp
-change the target temp by cycling through 3 pre-set settings, (for example 25°/35°/45°) using a simple button. (Note that I do not want to set the target temp via manual input but rather have 3 profiles to quickly change between. This is to match a certain ambient temperature to a certain 3D-printing filament)
-display temp on one line of a LCD and chosen profile on a second line
-use a wall outlet as a power source
What I want help with:
- do you see any problems with my thoughts above?
- what arduino board should I choose?
- what parts do I need to build this? LCD, tempsensor, pushbutton, some way to run the fan at 12V, what else?
