00:00:16.360 --> 00:00:22.260
Okay, okay, good. Now, Mho, you're a resistor, so you go in the middle.

2
00:00:22.960 --> 00:00:26.240
Okay, let's do this. Okay. Grab onto me, guys.

3
00:00:30.780 --> 00:00:33.220
Oh, it's working! I'm blinking again!

4
00:00:33.960 --> 00:00:35.120
Oh, let me see.

5
00:00:37.300 --> 00:00:39.360
Wait, I don't see any blinking, Ruby.

6
00:00:39.820 --> 00:00:42.600
Well, that's because you disconnected the circuit.

7
00:00:43.000 --> 00:00:44.400
Let's give it another go.

8
00:00:44.820 --> 00:00:46.540
Please reconnect us, Mho.

9
00:00:47.100 --> 00:00:49.040
Okay, let's do it.

10
00:00:49.860 --> 00:00:50.520
Grab on.

11
00:00:50.780 --> 00:00:51.080
Okay!

12
00:00:51.080 --> 00:00:56.100
Oh, oh, ow, okay, okay, I'm working, I'm blinking again.

13
00:00:56.300 --> 00:00:57.800
I will take your word for it.

14
00:00:57.900 --> 00:00:59.000
No, really, look.

15
00:00:59.660 --> 00:01:00.120
[unclear speech]

16
00:01:00.760 --> 00:01:02.860
Okay, guys, group meeting.

17
00:01:03.640 --> 00:01:08.100
You've got to stay still if we're going to make a circuit together.

18
00:01:08.800 --> 00:01:11.800
Sorry, Hans, I just got so excited.

19
00:01:12.340 --> 00:01:17.340
I understand, Ruby, but we need to stick together in order for the power to flow

20
00:01:17.340 --> 00:01:18.220
between us.

21
00:01:18.820 --> 00:01:22.280
Huh. You know, making a circuit is harder than I thought.

22
00:01:22.580 --> 00:01:27.740
Yes. Well, there is one thing that would make it much easier.

23
00:01:28.380 --> 00:01:29.320
What's that?

24
00:01:29.440 --> 00:01:30.060
A PCB.

25
00:01:31.160 --> 00:01:33.800
PCBs are awesome. I use them every day.

26
00:01:34.840 --> 00:01:37.180
Um, so what's a PCB again?

27
00:01:37.620 --> 00:01:41.220
A PCB stands for Printed Circuit Board.

28
00:01:41.460 --> 00:01:47.160
A PCB is a stable and sturdy way to connect electronic components like us together.

29
00:01:47.160 --> 00:01:53.060
Oh, totally. PCBs are the best. There's a board part, that's the flat

30
00:01:53.060 --> 00:01:53.960
and strong support,

31
00:01:54.160 --> 00:01:59.260
and then copper circuit traces are printed on top. That keeps LEDs like me

32
00:01:59.260 --> 00:02:00.540
connected and centered.

33
00:02:01.120 --> 00:02:05.740
Or integrated circuits, like me. What about resistors?

34
00:02:06.040 --> 00:02:10.300
Of course. And our best friends Cappy, Connie, Gus, and Billie too.

35
00:02:10.300 --> 00:02:16.020
Yes. PCBs can be simple, with just a single layer of

36
00:02:16.020 --> 00:02:17.320
copper circuit traces,

37
00:02:17.660 --> 00:02:23.080
or really complex, with multiple layers of connections stacked on top of each other.

38
00:02:25.800 --> 00:02:28.260
Whoa, how many layers can we make?

39
00:02:28.440 --> 00:02:32.580
Most PCBs are two layer, one top and one bottom.

40
00:02:32.820 --> 00:02:39.000
But for advanced circuits, like a phone or a computer, there can be up to 16 layers.

41
00:02:39.000 --> 00:02:44.040
Hey, guys! This PCB over here would be perfect for us! Check it out!

42
00:02:44.700 --> 00:02:49.260
What? You mean we had a PCB over here the whole time?

43
00:02:49.720 --> 00:02:52.360
Shh! Shh! Just go with it!

44
00:02:52.960 --> 00:02:53.460
Okay!

45
00:02:59.680 --> 00:03:04.700
Ah! This is a nice PCB! Very cozy, no?

46
00:03:04.700 --> 00:03:09.000
Absolutely! I could blink here forever!

47
00:03:09.700 --> 00:03:11.820
This is the life.
