There is a total of 4 matrix rows, each on a breadboard power rail.
|
||||
|
||||
The right matrix is connected to a microcontroller.
|
||||
The left matrix is connected to a I/O expander.
|
||||
The breadboard has four bus strips used as rows.
|
||||
Two rows connected to a microcontroller, and two rows connected to a I/O expander.
|
||||
|
||||
The I/O expander has a small notch on one end, which identifies the end with pin 1.
|
||||
In the picture, pin 1 is on the right end.
