The Arduino site has many get started projects, Youtube the same, most done in
breadboards (BB's). There are designs where layout is critical, like 16 - 20 bit A/D type
designs where absolute accuracy is of concern. Or high speed COM where buss
timing is critical. Those designs would challenge a solderless BB for sure.
But designs that time events like lights, dim lights, alarms....as you see from the
Arduino site and Youtube solderless BB's fine.
Just google "Arduino projects"
If you want to see some crazy but high performance linear design look at Bob Pease's
work, I had the good fortune of talking with him occasionally back in the 70's. Sat
close to him at work.
There are even RF work done with breadboards, many techniques for that construction.
Manhattan another technique.

At some point as a student or engineer you will probably need to breadboard a circuit either to verify its performance or for use in a project. Fortunately you can use modern solderless techniques to build breadboards that are robust enough to use with most student projects.
