I'm a first-year electrical engineering student, and I'm really enjoying what I'm doing, but I'd like to find ways to get into electronics in my spare time as sort of a supplementary learning method. I suppose micro controllers would be a good place to start, though I don't know much about them. Are there any good hobby electronics products that I can get (preferably cheaply) that would be good for a college student studying electrical engineering? Something that would be easy to buy would be a plus. I've already looked into the Arduino starter kit, but I'm wondering if there are any other options.
