=======================================

[keybrd_2_single-layer_annotated.ino](keybrd_2_single-layer_annotated/keybrd_2_single-layer_annotated.ino) explains how a keybrd sketch works.

You can view the class definitions in the [keybrd library](../src/).

After reading the sketch you will be able to modify it to suite your own single-layer keyboard design.
