These
are the types of questions you should be able to answer INSTANTLY, if
you want to design and build microcontroller projects. If you get less than
45, now's the
time to do the Basic Electronics course . Try the test again after the course, I'm sure you will
"fly" through the answers and be amazed at how much you have
learnt.
