I’ve always felt that Computer Science is somewhat of a liberal arts major compared to the hardy breed that is electrical engineers. So I’m taking an introductory ECE course to satisfy my own curiosity.
Today we had a simple lab demonstrating digital logic. I prepared part of the circuit on our breadboard and my lab partner finished the rest.
Unfortunately, nothing worked. I spent about fifteen minutes rewiring and pulling apart the circuit until nothing was left but the breadboard and a single logic gate. Even then I still wasn’t getting the output I expected.
I said, perplexed, “Well, I have no idea what’s wrong.” My lab partner stared at the board for a few seconds and then remarked, “Does it matter that you have the power source plugged into the GND line instead of the power line?”
I had pulled apart our entire circuit because I had forgot to plug in the power, once again reminding me that I should keep a safe distance from anything resembling hardware.
