The author has you burn up a couple of things to see what happens. This includes putting too much power through a LED that stops working with a satisfying little pop. I also burnt up two more accidentally while I was messing around a bit with some of my own circuits.
Learning through destruction! My kind of lesson.
The picture is of Experiment 3 in the book. Various resistors and an LED are hooked to a battery to see what happens. Directions are also given on how to check a resister with your multimeter to determine it's resistance rating. This is something that frustrated me tremendously in high school. I was always reading the stripes incorrectly. For those of you not in the know, a series of colored stripes tell you the rating of your component. This is all fine and dandy unless you are color blind, a disability I didn't even know I had until my physical for college.
My instructor and I in high school both assumed I was a lost cause when it came to electronics. I felt a great deal of satisfaction tonight as some thirty years later as I figured out the ratings on each resistor without having to figure out the colors. This is going to be fun.
Went as far as I could today with the components on hand. I skipped ahead a bit and messed around with the breadboard. Set up the same circuit from Experiment 3. Later tonight, I'll be going online to buy what I need for the next few lessons. While I'm waiting, I am going to practice soldering.
