You will need a breadboard keyboard with a Teensy 2.0 controller to run the tutorial sketches.
If you use a different controller, you may have to change port classes.
If you already have a keyboard with an Arduino compatible controller, you can use that instead of a breadboard keyboard.

When you finish this tutorial you will have a working keyboard and understand how a key matrix works.
## Why a breadboard keyboard is useful
A breadboard is the easiest way to learn keyboard electronics.
Electronics are fickle, you won't get everything right the first time, there is a learning curve.
Breadboards make the learning electronics faster and fun.
All the tutorial example sketches run on breadboard keyboards that have 2 to 8 keys.
Breadboard keyboards have row-column matrices and diodes just like the big keyboards.
Compared to full size keyboards on PCBs, breadboard keyboards are easier to learn on because:
A breadboard is the easiest way to learn keyboard electronics.
Electronics are fickle, and you won't get everything right the first time.
There is a learning curve.
Compared to PCBs, breadboard keyboards are easier to learn on because:
* Mistakes are easily corrected because no desoldering
* Parts can be reused in many different configurations
* A small keyboard is easier to trouble shoot
* Mistakes are easily corrected because no desoldering
Breadboard keyboards are useful for:
* learning keyboard electronics - diodes, micro controllers, I/O expanders
* learning the firmware development workflow
* prototyping circuits before making a PCB
* testing firmware concepts before building the keyboard hardware
* testing firmware concepts before committing to a keyboard-hardware design
## How a breadboard works
To understand the breadboard keyboard you will need to know the internal parts of a breadboard:
* terminal strip
* power rail
* terminal strip
