I am currently working as an automotive controller tester. When I first joined the company and started working with CAN, I was taught in a haphazard way—just told to "click the lightning bolt" or "connect this"—which made me wonder if I was actually learning it correctly. This course explained everything step-by-step from the basics, making it easy to follow. Above all, I liked that it didn't just cover easy topics despite being called "CAN Communication Basics!"
