Installing Examples
Simple Way
· Download Examples files form here.
· Rename the uncompressed directory to D1_mini_Examples
· Move directory to Sketchbook_directory
· The path will look like Sketchbook_directory/D1_mini_Examples
· Restart the Arduin IDE
· All examples are under File→Sketchbook→D1_mini_Examples
Git Way (Recommend)
We recommend using git to install Examples, you can always get the latest version of it.
· Clone repository into Sketchbook_directory directory (or clone it elsewhere and create a symlink).
cd Sketchbook_directory
