In this step we are going to organize the schematic and connect all of the components. This will bring you back to the library window. After you're done hit "Esc" on the keyboard. Click near the first one to add two more (make sure they are not touching). Since the photo-transistor and IR LED share the same package, we will have three of these packages in each cluster. The library window will close and you will have a schematic logo of an LED attached to your cursor. Click the drop-down menu by LED.Īll of the LEDs we are using (and the photo-transistor) are in 5mm packages, so click the package that says "LED-5MM" in the description. You should now see a list of each of the three devices we have: LED, RES (resistors), ZVN2110A (transistors). Scroll down to the library you downloaded, "prox_sens_LEDs", and click the drop-down arrow next to the library name. This will open a window that contains a list of all the libraries you have access to in EAGLE. To add a component, start by clicking the "Add" tool. Then after we put one together, we can copy and paste the group as a whole to add as many clusters to the future PCB as we want.

On the board I'm designing, there will be 8 separate proximity-sensing clusters.

For example, an LED (the device) comes in a 5mm bulb-like package that we will be using, but it also comes in a tiny surface-mount package (and other packages as well). This is because each device comes in different packages. You'll notice that there's many more than just three items in the library though. It should contain three simple devices: LEDs, resistors, and transistors. Click the drop down arrow here to to make sure everything in the library copied correctly as well. Click the drop-down arrow next to "Libraries" and scroll down searching for "prox_sens_LED.lbr" to make sure it downloaded. If you had EAGLE open already, close it and reopen it to refresh the libraries list. The main concern here is that it is in a library folder such as "lbr". It may be a different location on your computer, but the address should be somewhat similar. On my computer, this location was C:/EAGLE-7.1.0/lbr.

Once you download the library, move it to the appropriate folder so that it is easily accessed in EAGLE. To keep things simple and make sure you have all the parts we will be working with, I put together my own library that you can download here. There are tons of different EAGLE libraries available and many of them should have installed with EAGLE by default.
