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

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

## Exercises
1) Add a third column to the breadboard keyboard and sketch.

| Layout | **0** | **1** | **2** |
|:------:|-------|-------|-------|
|  **0** | a     | b     | c     |
|  **1** | 1     | 2     | shift |
