M Mastahh New Member Nov 24, 2010 #1 For a 5x7 Dot Matrix, i want it to display the Pound Sign (£) How would i connect it?? See my attachment for better viewing. Note: This is the character that will ALWAYS be displayed, and the dot matrix will never be turned off unless the whole circuit is turned off.
