Let me guess, you are using a recent emacs-26 pre-release version.  (The
CC Mode version number was updated to 5.33.1 a small number of weeks
ago).

I would recommend you to recompile arduino-mode in the Emacs you're
going to be running it under.  That should solve the version mismatch
error.

As for the main error, somebody (?yourself) is setting
arduino-font-lock-extra-types to t.  Almost certainly (I haven't looked
at arduino-mode's source), arduino-font-lock-extra-types needs to be a
list of, basically, arduino source identifiers[*] which should be
fontified as though they were types.  t here is not OK.  nil, (the empty
list), would be OK.

Again, almost certainly, arduino-font-lock-extra-types will have been
modelled on c-font-lock-extra-types, which can be found in
emacs/lisp/progmodes/cc-vars.c around line 1554.

[*] More precisely, this is a list of regular expressions which match
these pseudo types.
