To get started from hobby perspective, you can start with online electronics courses at Instructables[1].

If you are looking for something more academic to start with, check Computer organization/architecture and Embedded systems courses at [2] and [3]. UT Austin's Embedded Systems course at Edx.org [4] is also good place to start.
