Guys please help me with this question coz all the interviewers ask this to amature programmers. I have done my Embedded Systems course recently but wasnt able sort to this question. Thanks and reply soon.
"i was never taught that thing [driving a LED] and i was asked in an interview" As Jon suggested, that interviewer will also be thinking, "What sort of Embedded Systems course lets you get all the way through it without knowing how to drive a LED?!"
