Hi there, welcome to the eagle PCB designing course. In our last session, we have installed the Adafruit and smartphone libraries for using and creating our different projects. Now let's finish these ok diagram that we were about to create for the power supply. So this is the eagle's homescreen. And this is my project and this is the circuit diagram that we were about to create. Now as shown the last time also, what we need to do is we can either go to select this add part symbol, or I can just type it on here, attach and then we can add the components to our schematic.
Now there is one thing about Eagle that many times whatever components you search for may not be directly searched for you. Let's say for example, I want 1000 micro farad capacitor. So if I enter thousand micro added and enter, I won't get any results. So to search better in Eagle, what we need to do is make use of some wildcards. And the simplest and most common wildcards are putting an asterisk symbol on the beginning and at the end of the name of the component that you want to use. So it will search for every component that has anything and everything after and before the Select symbol, but it should just have 10,000 and I'll just press enter Now.
Now in this function library, I got 1000 micro farad radial capacitor exactly the same which we use for through all PCB as it was last also, the green symbol shows that it's up to all components. So right now we're going to use it to one components only. Let's add this capacitor. Right click to rotate Next image. Now let's add all the components that we were about to take diode one and 10414004. It's okay for me and let's arrange them in a rectifier fashion.
So this is how I arranged them. Then m 02. We've got the connector of looping. I'll put it here and one here. Then what I need is a 7805. Again, if I directly substitute 7804 I may not get some results, but by putting the asterisk symbol before and after, I'll get all the seven extra instances there.
Let's look into the Adafruit library. Remember, while selecting the component drones Select the components directly by looking at the name. Also look for the description which is the package of the PCB or the components PCB footprint. This is true or true 50 only assembly to 39 as a select package through hole, you want it to translate package and to 220 which is the most common and most popularly used package of 7805. I want this package so I'll select this ice by double clicking, just place it here you can just click on this symbol and start dragging your components if you want to drag it. So my basic components are here which are needed for me.
Now I need to connect them and moreover I lead resistor and led This will power on integration. So let's search for register actually delivers on its library. This is actually common register. That means I want just wildin. And then just list search for led five mm or three mm, whichever you're using. So an Adafruit library Bill Gates, led by them.
This is they're not connected. Now all my component placement has been done. All this component names are written over here. For the reference, this will be also added in your notes. One more thing that we need, and it's good to have. It's something called as wireframe.
It's not present here. Next added wireframe gives a nice eyes look to your symmetric name and sparkfun Library three military that's the name of file remedies for emulator looks good like this added frame lit. Now what we need to do next is we need to interconnect all those components and to interconnect them, we need to use a tool called neck. This one is the tool. So either you can go to the tool and select it here or just type it on where you're designing match and enter. It will give us a knit and whenever I come close to a component, it shows me a symbol like that.
So just click it once there. Then take your niche and click it again. Click it once. Click it again. Click it once, click it again for connecting it somewhere. So likewise, I will just complete this rectifier.
This is a transformer connector. So I'll connect the Transformers AC output at this point. Here I get a repulsive or pulsating DC and connect it to the capacitor for filtration. Then this is the input that was to search server. This is the ground connection. This is the output of center Jennifer giving our regulated five volts was the resistor register.
And this one was to led the LED booths down here. Then this is my output collector. So one pin goes to five volts and the other pin goes to ground. If you're not getting the layer, just click The middle button or the scroll button and drag the schematic and repeat it again. So, this is how you can drag it to places. So here we complete our schematic for the power supply.
These are the components that we have used and can also be used. So instead of the rectifier if you want to use the power jack, which is the DC jack, then we can also add this power underscore jack Rutledge. With this you can either connect the transformer or you can connect the power chip. This is what the project looks like through which we can connect and adapters drag it a little bit Choose net which just connected stupids to this two lines. Here you will by default see the name of your project whatever is the design done by whenever you save this I'm not saving it and all the details will present to you. So that's it for the schematic and next session.
Let's see how we can create a simple layout out of this power supplies image that's watching this video.
