All key-related events are served in the event handler for the on_kp() event. The
key_code argument carries the code of the key. Keycodes of each key are indicated
in parentheses on the drawing above. For example, key <5> has the code of 12Hex.
Each scan line of the keypad also controls one LED. To turn the LED on, set the
corresponding scan line LOW. This will not affect the operation of the keypad.
