" " and ' '

when do you use " " and when do you use ' '?

use " " for strings and ' ' for single characters. Ie: 'A', '1', "Hello". Obs: '1' != 1 (the character 1 is NOT the number 1.

In some cases, you can actually use the ' ' (single quotes) to also define a string constant in a long... for example:


unsigned long identTag;


identTag = 'BLUE';
