 Welcome to the show. We are here for JP's product pick of the week. That's me, JP, and this is the show where you can watch the show inside of a product page and get a humongous discount on that product. So let's, first of all, tell you where you can go to watch it if you wanna see it inside the product page and get a little bit of a hint as to what the actual product is. That right there is the URL. So if you head to Adafruit.com slash product slash 5200 or you can use that QR code right there if you wanna use a mobile device, you will be able to watch this video broadcast from inside the product page. And if you head there, not only will you see the video playing, but you will see that this week's product pick is a 50% off, half off during the show only. So that means you don't need a coupon code or anything like that. All you have to do is put the product in your cart and buy it before the end of the show or a few minutes grace period after the show and it will be automatically discounted. So it couldn't be easier. And before I go any further, what I'm gonna do is have Lady Aida tell us in her own words with her own video and hands and demos and pictures what this product is all about from the initial product launch. So take it away, Lady Aida. Why don't you? There's more cowbell. Yay. I could have used a little more cowbell. Okay, so the first cowbell, I mean, I always start with a prototyping board because that's how I actually prototype the other cowbells. So especially for the Pico W, if you wanna do IOT projects and you wanna use our Stemma QT sensors or if you wanna just easily reset your board, this is a little prototyping board. It's very inexpensive. It's designed to just be like a little throwaway. You can solder headers onto it, plug in your Pico, and it gives you a prototyping area. And then it also gives you a Stemma QT and a reset button. So it's kind of like a handy beginner getting your project started, but you don't need a lot of complicated extras. So the Pico, actually a lot of times people either have it with headers attached or they solder on headers. So that when you get the protocowbell, it does not come with headers. And the reason it doesn't come with headers is because you can configure it in so many different ways. You can plug in these skinny sockets. If you want to be super slim, you can put in these stacking headers, which I recommend, or you could put in these socket headers. And like we don't wanna assume which one you want. Personally, I like the stacking the most because it means you can then plug it into a breadboard like so. And then you plug in the Pico on top and you have a little bit of space over here. What does Christopher Walken say? I need more cabels. All right, well, he will keep going. So there's plenty of space you can solder in components, you know, capacitors, connectors, whatever you need to. There's an edge mount reset button. So reset button is not built into the Raspberry Pi Pico, but it's very handy. So if you want to go into bootloader mode by holding down the boot select and resetting, more of you just want to reset your board. So there's a little edge launch reset. So you don't have to unplug and re-plug your Pico to load circuit Python. And then on the other end, we've got a STEMI QT connector. So it's got a three volt power ground clock and data. And the clock and data are connected to pins IO four and five. So all the grounds are the square white rectangular because there's a lot of ground pins. And then this is the ground pad. Every pin has a duplicate. So, you know, every though, like this is, you know, IO 13 and there's, you know, this is what connects to the Pico. And then the pad next to it is you can jump or it. So every pin has like a little twin sister next to it. So you can jump her to it. And then the three volt line is the only one that has it's extended out. And this is all three volt because you'll probably need a lot of three volt power. And the rest of the pins are kind of like a little breadboard four row connects. And I think there's like 13 rows of four. You always cut the, you know, pads if you want to have them separated, but chances are you want to make multiple connections to each row. It's not a huge prototyping area, but it's designed to be, you know, skinny and fit underneath your Pico or Pico W for quick prototyping. And it's like only a couple of bucks. Oh, and one, one last thing. So the I squared C also has a breakout here. These four pins are the I squared C JST breakout. So clock data, three volt and ground. And that's for in case you don't want to use IO four and five, you can connect to the I squared C power and data and connect them to other pins. You shouldn't even have to use it for I squared C. You can use it for just GPIO. Like there's no pullups. So even though it's designed for I squared C usage, you don't have to do that. So this is our first cowbell. Yeah, that is it right there. That is the product pick of the week. You can see it nice and close up there. And let me go ahead and switch over to this camera. That right there is product pick of the week. It is the Pico. No, it is the Pie Cowbell Proto for Pico. That's a lot of P's. If you didn't know, the reason it's called this is that the Pico W, when the second Pico, the Pico W, which is the Pico with wifi on it came out, a lot of people started calling it the Pie Cow online that became popular. So Cowbell was the name that won for accessories that fit on top of or underneath the Pico, at least in the Adafruit world. And this one is dead simple, but it's super, super handy. In fact, let me bring up these two images so you can see them here. I can point to stuff there. You can see it's got the nice silk screen on the bottom there using penguin for the typography, nice high res type. You can see both the top and the bottom sides show you the GPIO numbers, which are usually what you're gonna call inside of Arduino or MicroPython or CircuitPython. Also lets you know which ones are ground. You have a few analog pins. Those are called out by analog names. You have tied prototyping area in the middle, little sets of four. You also have the three volt rail that's extended down from the three volt, which you can use on a few different components if you're prototyping a little circuit in there. And you've got the handy dandy reset button on one end. You have the STEMI QT connector for I squared C or quick as well on the other side there to plug in sensors and devices. And you can put headers into it socket style and put a pin header Pico on top or you can reverse that, which is actually what I did. So I wanna show you, this is my kind of favorite way to use it here. Let me switch over to a down cam and I will pull this camera out a little bit and I'll refocus so you can see that focus nice. That's pretty good there. So you can see here, this is a way that I like to use it which is a lot like a feather wing style or a shield style if you hearken back to Arduino add ons. And that is the unplug couple of things here. So there's a Pico with the thin socket headers on top and I've put the tiny little pin headers on the underside of my cowbell there. So now I can press that on and you can see I've made a whole little world of connections and circuits and things on the top here. And let me go ahead and plug this in and show you what it does. So I've got first of all a connector for a servo that I've put there and that's using some power ground and a PWM line. I've got I squared C stem of QT running out to a little OLED display here. I've added a, let me see, I've added a potentiometer here using one of the analog inputs, ground and power. I've added a button and I've added a little switch here and I've also added an LED. So when I plug this into USB power now, so it's just plugging into the Pico as normal, you can see here I've got my little plug-in OLED display. I've got a little potentiometer to servo action there. You can see my nice servo there. I've also got the angle showing up on my display, whatever angle I've turned that potentiometer to. And then I also have some little status things like when I press button, button shows up in text and I can flip between switch side one and switch side zero there on this little switch. So this is a really nice, neat, easy way to add on a bunch of additional circuitry and connectors to your Pico project. Like Lady Aida said, it also gives you a handy dandy reset. So if you have to reset for some reason, now you don't have to fish around and get a wire out and ground to the reset. You can just hit that button there and restart your project. And if you consider what I was doing before I had that, I had to go to a breadboard and make things big and lumpy and wiry with stuff all over the place. So it's a really nice way to neaten up your project. And also at this price, it's usually, I think, what $2 and we've got it on sale today for a dollar or 98 cents, it's a great price, it's a great way to add a little extra juge to your Pico projects there. So let's take a look at, here we've got the page, whoops, now I've done it. Right there it says, I'm gonna reload, make sure we still have these in stock, I think we stashed a bunch of them. Oh yeah, so we have a bunch of these in stock, you can get 10 of them max per customer, so that'll cost you $9.80 plus shipping if you wanna get a whole bunch of these that you have at the ready. Also, these are the kinds of boards that I like for other circuit prototyping. So having something with some doubled up pins, which is what these little end ones are, those allow you to just take every pin and if you socket that down into the Pico, you now get one exact copy of all of those pins, which is nice. And then you have nearby tied rows, which is perfect. It's sort of like a breadboard, sort of like a perma-proto. So I'll use things like this, even if it's not on top of the Pico, even though it's designed to fit on top of the Pico, I love little proto boards like this, they're really handy. If you take a look at the learn guides, I don't think we have a learn guide for this particular on its own, but we do have at least one example of this in a project already, which is this PicoW HTTP server by Liz Clark, and there you can see, we do have a fritzing object for that. So here's a little fritzing diagram of the stuff, the extra stuff she wanted, a little transistor here, some resistors, LED, and then having an OLED plugged into it, really handy. So if you take a look through this guide, you can head over to the wiring section, this will show you how she connected things up to have some sort of remote wired LEDs and so forth. So this is kind of a pain in the neck to do on just a breadboard or there's really nowhere to do it right on the Pico itself. So really nice way to add just that little bit of extra to your project. Let's see, what else? Code for this, there's not much actually to show because I'm just utilizing features that are on, so I won't show any code for that, but let me know if you have any questions before we go and I'll see if I hit everything I wanted to mention about this. Let me show my cool demo again down here, copy of my head up there. So let's see. Yeah, so we say Pico W, pi cow, pi cow bell. It's good for either Pico or Pico W. There is the Pico H, which has headers soldered underneath it, pin headers underneath it already. So you'd wanna add sockets to your cow bell in that case, but if you get the plain version of the Pico with no headers soldered into it, then you can choose top or bottom for the pi cow bell. Let's see, what else? Yeah, so it doubles all of the Pico's pins. It also gives you 13 rows of four-hole connected strips, those little breadboard-y style sections, and then you have that 3V3 rail. There's actually also a ground rail, so if I turn this off, I'll plug that. I can show you on this one and also on a blank one. Right here, this line of white here, this is all ground, and this line here, where you see the little sort of white dashes between them, that's the 3V3 line. I actually ended up on this, I realized I was gonna draw too much current on the three-volt line, and I wanted to use the battery or the voltage, actually the five volt from USB. So I ended up cutting a trace there. So you can modify the heck out of this, you can cut traces to make it do what you want, depending on how you wanna use it. So I actually did not need the long line of 3V3, but that could be optional or just use a subsection of that if you want to. And here you can see it a little better, probably on that one there. You've got the 3V3 line, which is these white dots right here, and there's your ground line. All of the ones that have a large section of white around them, the square, those are also ground. And as Ladea mentioned, you have your StemQT connector and you can also send that to other pins if you want. But by default, that goes to pins five and four for clock and data. I got those backwards by the way, those are not four and five for clock and data. They're the other way around. So in your code, you'll flip that around. Actually, you know what, that's one excuse to show, let me see, do I have, yeah, there's the code I have for this. Let me pull up that window there. I had this wrong at first and I was confused as to why and that is because I squared C equals bus IO dot I squared C, board GP five and board GP four. Not the other way around, which is what I tried at first. So we've got to be careful about that one. And let's see, anything else? I think that's it. Let me know if anyone in the Discord has questions about it. RetiredWizards says, how are the quick pins changed from four and five? That's an excellent question. I'd love to know if anyone has the answer to that because I'm assuming we need to cut a trace of four and five and run a wire pair of wires from the board over. So if you, let me show this again. There, and let me pick something to point with. So these are, I don't think these just magically take precedence. So I think we need to cut a trace somewhere. If anyone has done this, I'm sorry, I meant to find out the answer to this before the show. Lady Aida is busy right now, so can't answer this one. But if anyone has, also you can look at the schematic for this and see up on our GitHub. But I'm assuming we've got some traces to cut before we can do that. I could be totally wrong though. Yeah, cut traces was Todd's suggestion in there. All right. Mouse noticed that I called the button group butt group. Because I'm 12, sorry. All right. The headers I'm using for the demo, yeah, that's a good question too. If I can go, let me go find those. There are actually a few good choices for headers for these I think we probably have a link to them right on the page. So let me see if I have the page up. There we go. When you go to get when you can click on this, add stacking headers or add short socket headers or add regular socket headers. So I'm using this middle option, the short socket headers. If you click on that link, I think there'll be a, yeah, so these are two by 20. So 20 pins long, which is what you need. If you scroll down, I think you'll find the pin headers there. So this short plug headers for Pi Pico two by 20. So those are the two that I'm using, the socket and the pin versions of those. I really like those. I use the, we have an equivalent for the feather, short stacking headers for feather. I use those all the time for putting feather wings on just because there's usually not a reason to have that large expanse of space in there. So you can see, again, if I take these ones right here, one warning, you can plug these in backwards. You know, unlike Arduino or feather, there's not a sort of obvious polarity to this. So you want to make sure that you remember the STEMI QT connector is on the same side as the USB connector, but you can accidentally plug those backwards. Don't do that, you'll probably ruin something. So you can see there with these little short stacking headers, you still have some space in there for sure, but it is not as gigantic as with a regular header or the stacking headers are super, super huge. So I like these, depends on your project, though depends on what you're trying to fit. All right, DJ Devin three says, are the downloads on the page? I think since we don't have a learn guide page for this, you can get it from the product page. And let me see. Yeah, if you click on this technical details, Github repository, that'll take you to the PCB. And I'm assuming this is, I don't know what file we have here. I'm assuming, yeah, Eagle CAD file there. All right, I think that is gonna do it though. So let me go ahead and add a little connector. Oh, you know what? I've got one in the bag, that'll make it a lot easier. That's my product pick of the week this week. It is the Pi Cowbell for Pico. It is the Pi Cowbell Proto for Pico. That's the name of it. And I can set that right there. That one has a nice neat hang tag. All right, so don't forget head on over to that page, grab some right now for half off and you don't need a coupon code, just get them before the show is over, which is moments from now and you'll get the half off price. Maybe pick up a Pico if you don't have one. I think we might still have a limit on how many you can buy of those per customer, per lifetime, but I'm not certain on that. So check the, there's an FAQ I think on Raspberry Pi products. All right, thanks everyone so much for watching for Adafruit Industries, I'm John Park and this has been JP's product pick of the week. Bye-bye. Ba-da-da-da-da-da-da-da.
