I worked on this week’s P Comp assignment with Emily, and we learned that electricity can be dangerous if you aren’t careful with it. Apparently I messed up the placement of my power regulator on my breadboard, and as a consequence, soon after I connected the 12 V power supply to the board, I smelled something burning. I disconnected the power supply and then instinctively grabbed the power regulator, since it was still melting my breadboard. YeeeeOOOOOOOUCH! The tip of my right index finger was scorched like a piece of overcooked bacon.
Here we are measuring the voltage on a LED:
Here we are measuring the voltage with the LED connected to a potentiometer:
Here we are testing voltage in a series:
I guess I learned the lesson that Frankenstein’s Monster left for us all: “FIRE BAD! FIRE BURNS!”
