Teach me to robot.

I have an Arduino, and I want to make it do things. I gather that what I really want is a Raspberry Pi in addition to my Arduino. The trouble is, I don't know Python and my C and circuitry skills are severely rusty. So do you know of any online courses or physical books that will teach me all of this as a general subject of "making devices" rather than individual Python, C, and electrical engineering courses of study?

Just a stupid question that's puzzled me for years: Why is it that, on electric fans, the order of the settings on the switch is OFF - HI - MED - LO? I'm sure there's an electrical reason for this, but I don't know what it is, since I know nothing about circuitry. One would think that OFF - LO - MED - HI would make more sense. Can someone explain this to me?
