+||

+|| @description

+|| |    This is a demonstration of keypadEvents. It's used to switch between keymaps

+|| |    while using only one keypad.  The main concepts being demonstrated are:

+|| |

+|| |        Using the keypad events, PRESSED, HOLD and RELEASED to simplify coding.

+|| |        How to use setHoldTime() and why.

+|| |        Making more than one thing happen with the same key.

+|| |        Assigning and changing keymaps on the fly.

+|| |

+|| |    Another useful feature is also included with this demonstration although

+|| |    it's not really one of the concepts that I wanted to show you.  If you look

+|| |    at the code in the PRESSED event you will see that the first section of that

+|| |    code is used to scroll through three different letters on each key.  For 

+|| |    example, pressing the '2' key will step through the letters 'd', 'e' and 'f'.

+|| |

+|| |

+|| |  Using the keypad events, PRESSED, HOLD and RELEASED to simplify coding

+|| |    Very simply, the PRESSED event occurs imediately upon detecting a pressed

+|| |    key and will not happen again until after a RELEASED event.  When the HOLD

+|| |    event fires it always falls between PRESSED and RELEASED.  However, it will

+|| |    only occur if a key has been pressed for longer than the setHoldTime() interval.

+|| |

+|| |  How to use setHoldTime() and why

+|| |    Take a look at keypad.setHoldTime(500) in the code.  It is used to set the

+|| |    time delay between a PRESSED event and the start of a HOLD event.  The value

+|| |    500 is in milliseconds (mS) and is equivalent to half a second.  After pressing

+|| |    a key for 500mS the HOLD event will fire and any code contained therein will be

+|| |    executed.  This event will stay active for as long as you hold the key except

+|| |    in the case of bug #1 listed above.

+|| |

+|| |  Making more than one thing happen with the same key.

+|| |    If you look under the PRESSED event (case PRESSED:) you will see that the '#'

+|| |    is used to print a new line, Serial.println().  But take a look at the first

+|| |    half of the HOLD event and you will see the same key being used to switch back

+|| |    and forth between the letter and number keymaps that were created with alphaKeys[4][5]

+|| |    and numberKeys[4][5] respectively.

+|| |

+|| |  Assigning and changing keymaps on the fly

+|| |    You will see that the '#' key has been designated to perform two different functions

+|| |    depending on how long you hold it down.  If you press the '#' key for less than the

+|| |    setHoldTime() then it will print a new line.  However, if you hold if for longer

+|| |    than that it will switch back and forth between numbers and letters.  You can see the

+|| |    keymap changes in the HOLD event.

+|| |

+|| |  

+|| |  In addition...

+|| |      You might notice a couple of things that you won't find in the Arduino language

+|| |    reference.  The first would be #include <ctype.h>.  This is a standard library from

+|| |    the C programming language and though I don't normally demonstrate these types of 

+|| |    things from outside the Arduino language reference I felt that its use here was 

+|| |    justified by the simplicity that it brings to this sketch.  

+|| |      That simplicity is provided by the two calls to isalpha(key) and isdigit(key).  

+|| |    The first one is used to decide if the key that was pressed is any letter from a-z

+|| |    or A-Z and the second one decides if the key is any number from 0-9.  The return 

+|| |    value from these two functions is either a zero or some positive number greater 

+|| |    than zero.  This makes it very simple to test a key and see if it is a number or 

+|| |    a letter.  So when you see the following:

+|| |

+|| |    if (isalpha(key))    // this tests to see if your key was a letter

+|| |

+|| |    And the following may be more familiar to some but it is equivalent:

+|| |

+|| |    if (isalpha(key) != 0)   // this tests to see if your key was a letter

+|| |

+|| |  And Finally...

+|| |    To better understand how the event handler affects your code you will need to remember

+|| |    that it gets called only when you press, hold or release a key.  However, once a key

+|| |    is pressed or held then the event handler gets called at the full speed of the loop().

+|| |

+|| @description

+|| | This library provides a simple interface for using matrix

+|| | keypads. It supports the use of multiple keypads with the

+|| | same or different sets of keys.  It also supports user

+|| | selectable pins and definable keymaps.
