--- applyTo: "**" --- # Naming conventions for Arduino sketches 1. Required main entry file at /{project-name}/{project-name}.ino file 2. Additional .ino files are loaded in alphabetical order after the entry file. 3. Use naming convention lib-XX-name.ino for library files, where XX is a two-digit number to control the loading order. # Data sharing between files - Sharing is implicit. The compiler simply concatenates all .ino files together in order. - Do NOT use .h files. - Do NOT use "extern" declarations.
