- Tutorial 2 - single-layer keyboard
- =======================================
- The easiest way to learn the keyboard library is to read some simple sketches.
- [keybrd_2_single-layer.ino](keybrd_2_single-layer/keybrd_2_single-layer.ino) is a simple sketch with annotations that explain how a keybrd sketch works.
- The sketch will run on the basic breadboard keyboard described in [tutorial_1_breadboard_keyboard.md](tutorial_1_breadboard_keyboard.md)
-
- After reading the sketch you will be able to modify it to suite your own single-layer keyboard design.

-
- Exercises
- ---------
- 1) Read the four class definitions #included in the sketch.
- Classes are defined in the [keybrd library](../src/).
-
- 2) Add a fifth key to the breadboard keyboard and sketch.
- Not all rows have to have the same number of keys.
- The scanner should have enough readPins to cover all the keys of the longest row.
