Here is a Diptrace library made specially for Pakuranga College robotics courses.
Click on the link above and a screen opens which will allow you to download the file. Copy it from your Downloads folder and paste it into
Documents - Diptrace - My Libraries.
Start up Diptrace
Click on Library Tools and select "Add Library to User Patterns..."
Navigate to Documents - Diptrace - My Libraries and select the Pakbot2 library.
Now you should have access to a library which includes an Arduino UNO and most of the pads needed to make your shield.
