0:16Okay, okay, good. Now, Mho, you're a resistor, so you go in the middle.

0:22Okay, let's do this. Okay. Grab onto me, guys.

0:30Oh, it's working! I'm blinking again!

0:33Oh, let me see.

0:37Wait, I don't see any blinking, Ruby.

0:39Well, that's because you disconnected the circuit.

0:43Let's give it another go.

0:44Please reconnect us, Mho.

0:47Okay, let's do it.

0:49Grab on.

0:50Okay!

0:51Oh, oh, ow, okay, okay, I'm working, I'm blinking again.

0:56I will take your word for it.

0:57No, really, look.

0:59[unclear speech]

1:00Okay, guys, group meeting.

1:03You've got to stay still if we're going to make a circuit together.

1:08Sorry, Hans, I just got so excited.

1:12I understand, Ruby, but we need to stick together in order for the power to flow

1:17between us.

1:18Huh. You know, making a circuit is harder than I thought.

1:22Yes. Well, there is one thing that would make it much easier.

1:28What's that?

1:29A PCB.

1:31PCBs are awesome. I use them every day.

1:34Um, so what's a PCB again?

1:37A PCB stands for Printed Circuit Board.

1:41A PCB is a stable and sturdy way to connect electronic components like us together.

1:47Oh, totally. PCBs are the best. There's a board part, that's the flat

1:53and strong support,

1:54and then copper circuit traces are printed on top. That keeps LEDs like me

1:59connected and centered.

2:01Or integrated circuits, like me. What about resistors?

2:06Of course. And our best friends Cappy, Connie, Gus, and Billie too.

2:10Yes. PCBs can be simple, with just a single layer of

2:16copper circuit traces,

2:17or really complex, with multiple layers of connections stacked on top of each other.

2:25Whoa, how many layers can we make?

2:28Most PCBs are two layer, one top and one bottom.

2:32But for advanced circuits, like a phone or a computer, there can be up to 16 layers.

2:39Hey, guys! This PCB over here would be perfect for us! Check it out!

2:44What? You mean we had a PCB over here the whole time?

2:49Shh! Shh! Just go with it!

2:52Okay!

2:59Ah! This is a nice PCB! Very cozy, no?

3:04Absolutely! I could blink here forever!

3:09This is the life.
