How is LED interfaced with 8051 on its board

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.

  • The reason this question is asked is because the answer is VERY simple. If an interviewer asks this question to an interviewee who doesn't know the answer, the interviewer knows the interviewee is probably pretending to know something he doesn't.

    My suggestion is to do a little research and try to figure it out on your own.
