If you are writing a post or sharing an Arduino project a great way to show your schematic is using scheme-it and it is even easier with the if you have a starting point. One of our Techs here at Digi-Key created a custom Arduino Uno design Starter.
This starter has pins representing each header location on the Arduino. This makes it easy to connect any other components and easy show and explain your next arduino project… Click here to open this starter and start your own schematic.
With this starter you can add your own parts, labels and wires to show how your project is assembled. For more information on using Scheme-it see our Scheme-it section.
