 free software. So if you go to this website Fritzing, it's I believe it's a German company. It kind of was born due to the maker movement itself, whether it's Arduino or Raspberry Pi. And how many of you are involved in teaching electronics? Do either kids, I know Gabby is there, either electronics. I've also done a couple of workshops at General Assembly even for adults. So I found Fritzing very, very useful in the sense that you can do some breadboard pictures with it as well. So go to Fritzing and you can download it. And I'll be talking about a couple of things, how to kind of do the breadboard diagram for beginners, as well as how to edit a part in Fritzing using SVG, which is also an open source standard. Okay, I cannot use, I need three hands for this. All right, so what I'll do is I will start up Fritzing. Oh, no, no, no, it's fine. You can hear me, right? If not, if not come, let's be closing. Come closer and be closing. All right, so I'll start up Fritzing here. And it's really, I feel the easiest of all the four. And that's why I'm introducing this. So you can come here right over here. Maybe I should start the mouse locator. Okay, you can see this. So over here, you will see the search button. And then you can simply start with, say, a breadboard. And what I find good about this, you know, especially when you teach a beginner, they cannot relate the physical device with the symbol. Like, you know, the resistor is like this, right? But it physically looks very different. So I find Fritzing very useful for that purpose. So for example, here you can draw the breadboard here, which is the first thing they start. And then it can be, you know, like a resistor, something like this. And the cool thing is when you kind of like drag and drop it, notice here how these green things will get highlighted to say that these are all energizes well. So go ahead and find more parts. So the good thing is, people are continuously adding to the parts library here. And I think you will also hear from Ego or Kaiket about these kind of community. So Fritzing has like parkfront, eat a food and lots of stuff. There is also the schematic version of it. So if you want a schematic, they will automatically also create one. And there is, of course, a PCB one. But I have never used the schematic and the PCB one. The mostly that I use is the breadboard version. And then I have a picture. For example, today, what I did, I went to Johnny five and then I did a example on tilt. Maybe I should show you one. So I had to do, so you can see that this example here, it's all done with Fritzing, all these breadboard diagrams. So I find them really, really easy. So whenever you need to show physical how it looks like, you can use Fritzing. The next thing I want to show you in Fritzing is how to edit a part. And this is something I found very useful. So in Fritzing, what you can do is let's find something. Let's find tilt. It's a tilt switch. So in Fritzing, you can actually go here and then you can export the part. Let's export it. So when you export it, it will give you this weird file extension FZPZ. So let's export that. And over here, this is how it will look like. The cool thing about this is if you change this to a dot zip, you can actually unzip it. And once you unzip it, it will become a folder and inside the folder, guess what there are like about like five files. One is with the breadboard. This is how the SVG looks like. The other one is the icon, which is also the same as the breadboard. The one, this one is the PCB. And the last one is the schematic, as you can see. So what we are going to do now is we're going to try to edit this. And in order to edit this, I know if you ask Leon, he'll probably use Adobe Illustrator. But once again, I'm going to use another free software and it's called Inkscape. So what I'm going to do, I'm going to open this with Inkscape. Let me show you the website of Inkscape. You can also once again go ahead and download it. It's free. So let's try to edit this. Okay, so this is the tilt switch and I'm going to try to edit this. So let's go here. Let's blow it up, blow, blow, blow. And let's say, just for the sake of example, I'm going to try to delete this part. Delete it and delete it. Now it is infringing. If you want to create a new part, it's always, always good to edit an existing one. So if you are trying to create a resistor, find another resistor and try to edit it. Because SVG, which is made up of a lot of XML tags, if you come here and look at the XML editor, you see that the editor has IDs like connector and the pins. And this is how later on freezing will identify these names and use this connection to connect up in the breadboard. So the names are very important. The first time I tried, I tried to do it with a bare SVG. It does not work. So try to edit an existing one. So yep, I'm just going to remove this. And let me just save it. Save as I'll save it on the desktop and say example dot SVG. Please choose an SVG format plain SVG that will do save. Right. And then you can quit. Now what you do, you come back to here and let's this time you will click edit part. So let's click it. And there you go. You can edit now. So you can have a few looks of it. This is the schematic. This is PCB. This is icon. And this is the metadata. And these are the connectors, the pin names. So what I'm going to do now I'm going to load the image. And this time I'm going to go and choose the example that I created this one. The one without the inner part of it, you know, just for example. And similarly, I'm going to do the same thing for the icon. I'm also going to choose the example here. All right. And then I'm going to save it. Sayani switch. I don't know how this works, but yeah, this is my switch. All right. And that's it. Now I have a part called this one, a new one that it can be used here. And the first time I created, like I said, when I made completely new, these lines did not work. You see these energized lines, but now it works. And similarly, you can also go and export it and save the part here. You can edit it and so on and so forth. Okay. So freezing is really easy. If you want to create some electronics, especially the breadboard part of it, you can use frinsing. Do you have any questions? So I find personally, if you go to GitHub, if you go to GitHub and then you kind of search for frinsing, you will basically find AdaFood spark fun libraries inside there. And you can send a pool request as well. So you see here, this is like by AdaFood, right? This is the one by frinsing. Go and have a look at their ones. So they have all the SVGs inside there. So I'm frinsing itself, by the way. So if you create a new part, remember to send the pool request there. My talk is really short. It's just an introduction to what a software is. Maybe I'll just take one question. Any question? All right. If not, yes. Yes. Yes. There are wires inside. Yes. So that's a good question. So yes, that's right. So you can actually just drag and drop like what it knows said. And so let's say I drag drag from here and you can actually edit it as well. So you can let's say, you know, you're you're putting this to like a live wire. So it can be read. You can also use command and then kind of bend it. Yes, you can. You can. You definitely can. So I'm going to stretch one from here to here. Yeah. Like I said, I find the breadboard one most easy for beginners, you know, like, like a picture. Like if you go to, I don't know if you deal with Johnny five, like, like these, this example, like let me give you something like a switch, let's say, okay, a servo or something like that. You know, this is much more related, relatable to a beginner than somebody who has already done electronics. Then that person can do with schematics, but this is so needed for beginners. So I highly recommend fritzing when you are using it. For teaching. I think Gabby would know even better. Yes. Yes. Yes. Yeah, I think I can you annotate it. I do not know. I have personally used another software called sketch. I've actually used sketch for this. Yeah, because I remember there was a note bolts going on and Chinme another guy was doing the circuit and so I helped him prepare the dots and I had to put in annotations for that because over there the people coming in had JavaScript background, but not electronics. So I use sketch because it had like bright pink annotation. So I find sketch and fritzing goes very well. So thanks for the question. So sketch and fritzing and in-scape. All right, I think I will take the questions. Let's have more questions after it. So can make with Eagle. Eagle is the boss.
