Previously, although the licensing was indicated by informal comments in most of the sketches, a formal license was not provided. This project is not truly a library, but rather just a collection of sketches packaged as a library in order to allow distribution via Library Manager, but without any library source code. So it is those sketches that are the significant content of the project, for which licensing must be defined. As is standard practice for the example sketches created by Arduino, this project's sketches contain the statement: > This example code is in the public domain. The appropriate formal license in this case is Creative Commons Zero v1.0 Universal. A standardized Creative Commons Zero v1.0 Universal license file is hereby added to the project. In addition to providing this important information to the project users, this will also allow automated license type detection (e.g., by the Licensee Gem used by the GitHub website). --- LICENSE.txt | 121 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 121 insertions(+) create mode 100644 LICENSE.txt diff --git a/LICENSE.txt b/LICENSE.txt new file mode 100644 index 0000000..0e259d4 --- /dev/null +++ b/LICENSE.txt @@ -0,0 +1,121 @@ +Creative Commons Legal Code + +CC0 1.0 Universal + + CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE + LEGAL SERVICES.
