You are about to watch 25 minutes of video just on wires and wiring! Yes, 25 minutes on wiring, whereas there was only about 5 minutes on electricity, current, and voltage.

You may think that the challenge in designing circuits that work will be complicated math problems or something equally confounding, but it probably won't be. It will probably be little mistakes you make with wiring circuits on your breadboard. With that in mind, please make sure that you feel good about your wiring skills before you move on from this page.

You should only use 22 AWG (American Wire Gauge) solid hook up wire on your breadboard. You should always have red, black, and at least one other color on hand so you can color code your circuits.
