Tutorial 0 - Introduction

The first two tutorials are intended to be read in sequence:

1. Breadboard keyboard
2. Single-layer keybrd

Tutorial 1 is about making a breadboard keyboard, which is used in tutorials 2 through 6. Tutorial 2 is needed to understand the remaining tutorials. The remaining tutorials can be read in any order.

You will need a breadboard keyboard with a Teensy 2.0 controller to run tutorial sketches 2 through 6. If you use a different controller, you may have to change pin assignments and port classes. If you already have a keyboard with an Arduino compatible controller, you can use that instead of a breadboard keyboard. All the tutorial sketches use 2 to 8 keys. If your keyboard has more keys, they are simply ignored by the sketch.

The tutorials assume the reader:

• is familiar with C++
• is new to Arduino, firmware, controllers, and the internal workings of keyboards

All the tutorial sketches are tested on teensy 2.0 and PCA9655E-D I/O expander

The tutorial sketches will be changed to Teensy LC and MCP23018 I/O expander

Some of the pictures do not match the sketches, they will be updated after changing to Teensy LC

Schematic diagrams are missing from tutorials 2 and 4, they will be added after changing to Teensy LC
