Step 10Eight LEDs a glow-ing!
How do we get the other half of the LED X to light?
To answer this question, we must again appeal to SCIENCE!
Here's a schematic showing eight green LEDs, with a line between each pair of four, as we discussed earlier. Note there's a plus and a minus on each pair. All we have to do is hook up both of the plusses and minuses to complete the circuit and make all eight LEDs glow.
Do this with some alligator clip test leads "et voila"!
