/* keybrd_5b_LED_on_IOE.ino

This sketch:
    is a simple 1-layer keyboard with CapsLck indicator LED on I/O expander
    runs on two matrices of a breadboard keyboard
    modified keybrd_4c_split_keyboard_with_IOE.ino by adding LED_CapsLck

This layout table shows left and right matrices:

| Left  | **0** | **1** | | Right | **0** | **1** |
|:-----:|-------|-------|-|:-----:|-------|-------|
| **1** |   1   |   2   | | **1** |   3   |CapsLck|
| **0** |   a   |   b   | | **0** |   c   |   d   |
