Splitting string into pair of characters in Ruby

I have a string (e.g. "AABBCCDDEEFF") and want to split this into an array with each element containing two characters - ["AA", "BB", "CC", "DD", "EE", "FF"].

From stackoverflow

• Try the String object's scan method:

  >> foo = "AABBCCDDEEFF"
  => "AABBCCDDEEFF"
  >> foo.scan(/../)
  => ["AA", "BB", "CC", "DD", "EE", "FF"]
  

• Depending on your needs, this may work better:

  >  foo = "AAABBCDEEFF"
  => "AAABBCDEEFF"
  > foo.scan(/.{1,2}/)
  => ["AA", "AB", "BC", "DE", "EF", "F"]
  

  Not sure what your input looks like. The above answer will drop any characters that do not have a pair, this one will work on odd length strings.
