Mini-Paint v1.3

Development Boards Arduino
1

Worked on the paint program some today, pushed it up a notch.

Now we have 2 added colors to complete the palette, and one more brush thickness to round out

a 5-brush set.

Added BRIGHT_RED to palette (Pink)

Added GREY2 to palette (darker grey)

streamlined the flow a little bit, cleaned house.

Ability for even finer detailed paintings is now possible.

Suggested that a stylus made from toothpick or similar semi-sharp non-scratching object

be used, as blunt objects or fingers are now too clumsy for the smaller buttons and details.

**Next revision FAT storage option for SD shields for harvesting your image.

Enjoy
