We do this by first clicking on the rename tool. Next we click on our first set of connectors and rename them to D1.
Do this for the other connectors D2, A1 and A2 Respectively. Now we want to add some grounds to the cathodes of our LED's. We first have to get them from the ADD menu. We need to flip the pins around on our D1 and D2 Connectors. We do this by clicking on the mirror command.
Next we want to click the Group command. Then we drag a box over all of the connectors in D1 and D2. Be careful with the placement. If it gets place in an area that was unintentional you can just click Move. Right-Click on the schematic, and click Move: Group.
Then move the connectors to where you want them to go. Now it is time to draw some connections, more specifically we want to connect our LED's to the resistors and grounds along with wiring them into some pins on the connectors.
We do this by selecting the Wire button. Once the wire tool is selected we then click on one of the ends of a connector In this case D1. Then draw a line to our first Resistor. Please note that to start a wire you click on the start point, any joints you want to make in the wire just simply requires you to click and change direction. Once you connect your intended parts together hit ESC to cancel making more lines connecting from the start point. Repeat this process for each connector to each resistor, then go from resistor to each LED anode, and finally finishing up with each LED cathode connected to ground.
Now that we have all of our LED's ready to go we then can focus on the switches. We need to add more grounds and resistors to them before we can do anything else. You can add them to the schematic under the switches similar to what is shown.
Don't forget to give each resistor a ohm value. Next using the wire tool from before connect the grounds to the resistors then the resistors to leg 3 on each of the switches. Now we need to add some junctions to each of the Pin 3's of our switches. We just have to click the junction tool. And now we just click each Pin 3 on our switches. Once you get the junctions on the schematic, then you go ahead and click on our wire tool. Now we need to connect each junction to some connectors.
Now that we have our switches grounded we need to get some power to them. We then place a source above the Pin 1 of each switch. Now we can also put a source while we are at it by A2 and connect it to pin A You can rotate the placement of parts before inserting them by Right-Clicking before placement.
Place it near A Now our schematic is complete! You will notice most of the Analog pins and half of the Digital pins aren't connected to anything at all. This is intentional by design, we don't need to connect every pin, just enough to drive the parts we need and feed it the 5v of electricity. You will notice a lot of errors even though we did the schematic correctly. All of these errors can be disregarded because as it was mentioned before not all pins need to be connected.

You can adjust the grid size of the PCB Layout editor, if you want. Now, using the group option from the side tool bar, select all the components and using move option move all the components and populate the board area.
Using the move option, place the components on the board as per the position you want the component to be on the board. You can see thin yellow wires running between the components. These wires are called air wires and are representation of connections between components.
When we route the path between components, these air wires will disappear as an indication of successful connection. Now, it is time to make the connections or traces for the Printed Circuit Board. For this, we are going to use the Route tool from the side tool bar. Also set the width of the trace to be routed as your requirement. Then, select the signal layer i. Start routing the traces from pin to pin. As you progress with routing, the air wires will start disappearing.
Complete all the connections and make sure that one trace do not interact with other as this is considered as a short circuit. Adjust the size of the board as per the required dimensions and save the file. The board file will be save with. Select the polygon option from the side tool bar and start drawing the polygon along the edges of the board. Make sure that the signal layer is bottom.
The starting and ending points of the polygon must meet. Now you need to open your component libraries. By default, all the libraries are open in Eagle CAD, making it challenging to choose parts from the library. For convenience purposes, download the design project library.
In the Edit button, click Add , and then Select component. Remember, every open library in the ADD panel comes with a components list. Some parts contain more than one package. All components have descriptions you can check to know their functions. The ADD panel will disappear. Also, a schematic outline will trail the mouse when you place it above the primary schematic sheet panel. Left-click to position your components. You can add any number of parts in any order. Besides, you can also place and even rotate pieces as you include them in the schematic.
Nevertheless, you can still move legs after introducing them using the Edit and Move commands. You need to add a frame to your schematic to make it appear neater. Go to the Draw button, select Frame , and click the corner frames to add a frame. Later on, you may change the location of your Frame in case of huge schematics. The good thing with Eagle software is that you can delete and redraw frames anytime. Navigate to the Draw button and select Net to link components. Left-click the source pin end to change direction.
The software will create a connection and label it green, and it will also create right-angle bends automatically. If you want to undo your nets, go to the Edit button and press Undo. If you want to link far-away subnets, you must select appropriate alphanumeric names. Go to the Edit section, choose Name , and click on every Net you wish to connect. It would help if you assigned them a similar name to link them. To make your connections visible, go to the Draw section and click Label to include a label.
Now, to obtain signals on and off the board, you require either connector parts or linking wires. The best method of joining wires to a prototype board is through terminal pads containing soldered circuit pins. Introduce test points to your internal nets. The test points will show up on your schematic as small pads that resemble terminal pads. After adding components, frames, and nets to your schematic, you should conduct an ERC test to count it done. The test will help you to identify adjacent pins and traps that are not linked.
