I began working on the week 3 lab for Pcomp today. Pretty straight forward stuff, it would seem. The problems began when I bought a longer breadboard from a 2nd year student, thanks Stream, (no sarcasm intended the fault was all mine.)
I spent about 3 hours trying different combinations of wiring examples and set ups, from the labs to the arduino examples. I could not get power to a LED!
So I began trouble shooting from the end that I knew had power, the board. I worked from component to component to find the problem. It just did not make sense. Until Druv said, “Hey does that break in the breadboard mean that power stops there?”
Sure enough. I put a jumper cable over the break in the middle of the board and shazam there was power to the entire board.
It took about half an hour to finish the lab after that.
Use your multi-meters boys and girls.
