Step 1: Download the Library You Want to Use

After a quick Google Search I found a nice library for the ATttiny85 on Eagle CAD's website linked here:

Eagle CAD Libraries

Step 2: Create a Folder to Place the Library in

Create a folder wherever you want the library to be kept.

I kept my library in my DropBox under the folder called eagleLibrary

Step 3: Drag the Library to Your Folder

If the library downloaded as a zip file make sure you extracted it first before placing it in your folder

Otherwise just drag and drop the library to the folder we created in the previous step

Step 4: Tell Eagle CAD Where to Look for the Library

Open Eagle under Options->Directories

Step 5: Under the Directory Type the Library Location

The modify the path location to tell Eagle exactly the folder location and name where it will find the library. Note capitalization counts!

Mine looks something like this:


This just means something like this


Step 6: Check In

If done correctly you should now see the folder with the library show up


Right click your library the select Use All so Eagle CAD knows to use the components in this library
