Auto Adjusting 12 V fan

Hi all,

This is my first time working with the Arduino software. I am building a 12 V fan that auto adjusts to the surrounding temperature. There will be a switch that will do the following: turn on low, turn on high, turn on auto, and turn off. There will also be an IR remote that will (hopefully) do the same as the switch. With each of the "on" settings (low, high, auto), there will be an LED that indicates each. There is also an oscillating motor that turns the fan. I have no idea where to start or what codes to use. Any help would be appreciated. Thank you in advance.

I would start with the basics first. Load and example sketch to flash an LED. Then build a circuit to control the fan speed, write the code to adjust the fan speed and so on.

Posting in three different places of the forum is the last thing you want to do.

That will get you banned quickly.
