So how old are you, how much compsci background do you already have, what is the class supposed to include, what is the teacher's background (especially WRT microcontrollers as opposed to desktop programming), and is this supposed to be more of a "thesis" or a "project" ?
"Interfacing Real World Sensors to using Arduino" seems like a pretty catch-all title that might work well and give you a broad space to explore in more or less detail as time and interest dictate...
