I am quite new in this field, i have been practicing electronics
system design for about 2 years. From my experience in
microcontrollers, both hardware and software had caused problems.
Assuming that the electronic design is correct, it turns out that bad
hardware assembly causes problems the most (e.g. bad PCB, bad
soldering joints, etc). Second, bad components. Third, bad firmware code.

I just want to know, if you assemble the electronic hardware yourself,
and you use cheap components like here in Indonesia, so that the
quality isn't so good, what would you check FIRST in case of an
unexpected error of your microcontroller system?? Your hardware or
your software? Because i often waste time checking on one of them
while the problem actually is on the other one :(

Thank you.
