Tutorial 2 - single-layer keyboard
|
|
=======================================
|
|
The easiest way to learn the keyboard library is to read some simple sketches.
|
|
[keybrd_2_single-layer_annotated.ino](keybrd_2_single-layer_annotated/keybrd_2_single-layer_annotated.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.
