P is for PCB automatic captions, checked for structure and key terms; corrections welcome [00:00:16.360] Okay, okay, good. Now, Mho, you're a resistor, so you go in the middle. [00:00:22.960] Okay, let's do this. Okay. Grab onto me, guys. [00:00:30.780] Oh, it's working! I'm blinking again! [00:00:33.960] Oh, let me see. [00:00:37.300] Wait, I don't see any blinking, Ruby. [00:00:39.820] Well, that's because you disconnected the circuit. [00:00:43.000] Let's give it another go. [00:00:44.820] Please reconnect us, Mho. [00:00:47.100] Okay, let's do it. [00:00:49.860] Grab on. [00:00:50.780] Okay! [00:00:51.080] Oh, oh, ow, okay, okay, I'm working, I'm blinking again. [00:00:56.300] I will take your word for it. [00:00:57.900] No, really, look. [00:00:59.660] [unclear speech] [00:01:00.760] Okay, guys, group meeting. [00:01:03.640] You've got to stay still if we're going to make a circuit together. [00:01:08.800] Sorry, Hans, I just got so excited. [00:01:12.340] I understand, Ruby, but we need to stick together in order for the power to flow [00:01:17.340] between us. [00:01:18.820] Huh. You know, making a circuit is harder than I thought. [00:01:22.580] Yes. Well, there is one thing that would make it much easier. [00:01:28.380] What's that? [00:01:29.440] A PCB. [00:01:31.160] PCBs are awesome. I use them every day. [00:01:34.840] Um, so what's a PCB again? [00:01:37.620] A PCB stands for Printed Circuit Board. [00:01:41.460] A PCB is a stable and sturdy way to connect electronic components like us together. [00:01:47.160] Oh, totally. PCBs are the best. There's a board part, that's the flat [00:01:53.060] and strong support, [00:01:54.160] and then copper circuit traces are printed on top. That keeps LEDs like me [00:01:59.260] connected and centered. [00:02:01.120] Or integrated circuits, like me. What about resistors? [00:02:06.040] Of course. And our best friends Cappy, Connie, Gus, and Billie too. [00:02:10.300] Yes. PCBs can be simple, with just a single layer of [00:02:16.020] copper circuit traces, [00:02:17.660] or really complex, with multiple layers of connections stacked on top of each other. [00:02:25.800] Whoa, how many layers can we make? [00:02:28.440] Most PCBs are two layer, one top and one bottom. [00:02:32.820] But for advanced circuits, like a phone or a computer, there can be up to 16 layers. [00:02:39.000] Hey, guys! This PCB over here would be perfect for us! Check it out! [00:02:44.700] What? You mean we had a PCB over here the whole time? [00:02:49.720] Shh! Shh! Just go with it! [00:02:52.960] Okay! [00:02:59.680] Ah! This is a nice PCB! Very cozy, no? [00:03:04.700] Absolutely! I could blink here forever! [00:03:09.700] This is the life.
