What specifically are you looking to learn though?
Do you want to learn about digital hardware - how chips and components are constructed using AND, OR and NOT gates? This will give you a pretty good idea of how hardware works, but the projects will be limited to you, a breadboard and some switches - not terribly exciting stuff.
On the other hand, if you want to learn build simple robots and such, you'll have something neat to do, but at the end you likely still won't have an idea of how a CPU works or GPS chip works.
