It describes what is connected to what, and how. It does not describe what the PCB will look like. The important parts are to make sure the schematic layout is simple, and readable.

We need to get some parts in there. It looks a little like a plug with a pointer on it. The right-hand side shows information about the item in the left-hand side. The methodology here puts all capital letters ahead of the lower-case ones. The list goes from A-Z, then from a-z. Choose the SparkFun item, and click on the plus sign to expand it. You can click through the different shield options to see what the device footprint looks like.

Figure out a place to put it down and click your left mouse button. EAGLE will set down the package. You should now have something that looks a little like this:. When you click on it, the schematic package and the device footprint will be shown.

Click okay, and put down 6 of these guys. Lay down the resistors just a little bit away from the Arduino package,. Now you want to lay these out.

You can remember which side is which with a simple mnemonic device: A is for Anode. That is, the end of the LED with the arrow is the Anode.

Another easy thing to remember is that the side with the line, is the Cathode. That line turns sideways and becomes a negative symbol - or ground. Now, for our shield we also want to throw in a way to easily connect some inputs, namely sensors. The easiest way In my opinion to do this non-permanently is to implement a terminal block. Terminal blocks are those things you can screw, clip, or lock wires into place.

The connectors are conductive so pushing the wire in makes it part of the circuit. Most often these come in 3. They make the part stay in place more easily when you flip the board to solder the pins. This will just give us screw access to the 5v line and the Gnd. A 2-point terminal block is a lot like the 3-point one we just added.

Stick it in, and you should have something like this:. You do not. The net button is a little tidier than the wire button, does things right, and makes everything better. The Net tool button looks like this:. Select it. When you click on the wire, it starts another segment. Start at the pin on the Arduino, and click. You should now be dragging a line. Click again to create another segment.

This will stop the line. Do this for all 6 PWN pins and you should have something like this:. Everything should go in order, except for the power block. Because of the way the pins are setup on the device, we want to pull the bottom most ground pin from the Arduino and the 5v line. We just need to complete our circuit to make everything work right. To do this, we need to run a ground line over to the LEDs.

Why the top GND line? Well, the way that the schematic translates to the board later, puts one of the GND pins on the side with the digital pins, while the other two are on the side with the analog pins. So this is for convenience. You never know when something will go wrong and take away all your hard work. You may want to try laying out the whole thing over again, just for the sake of doing it. Now the fun part! I call this the fun part because I enjoy the process of figuring out how to put together the circuit in a way that makes sense.

The button looks like this:. We need to move all of those parts into that white square. This should highlight all the parts. You want to move all of these things inside the white box. It is absolutely crucial in PCB design. To begin, click on the Grid button in the upper left hand corner:. This will bring up a dialog. I like to work in 0. When I get to positioning the components, it can be useful to have. Do whatever works best for you. That is, the top is viewed either as the side with the USB connector, or the side with the digital pins.

For whatever reason, when SparkFun put together their Arduino component in EAGLE, they make the component default to a position with the digital pins on the left-hand side. In order to make it easier to work with, I rotate the whole thing. So now you should have something that looks like this:. Basically, move these components around until they make sense in their layout. The simpler the path is, the easier it will be to understand later.

Try to keep them as straight forward as possible. The particular ones that SparkFun sells actually interlock. Because the footprints are tightly controlled, it can be a little difficult to position them correctly. I'm a noob to PCB designing and electronic stuff. I want to design a pcb shield which is compatible with an Arduino mega I'm using Eagle CAD. I checked the sparkfun library but I couldn't find a way to design Mega Shield.

Can anybody give me a library or any alternative way to do this? Since you're new user, perhaps it's easier to take an existing project and modify it for your need.

For Eagle, examples can be found on Github. It's more fit for sharing an collaborating designs and libraries. You can easily fork an existing board and use their community parts repository.
