00008 To power a LED 7x5 dot matrix.

00010 This project uses the display from RS Components: 247-3141.
00011 
00012 The connections are as follows:
00013     Pin 16 = column 1 Display pin 1 (left-most column)
00014     Pin 17 = column 2 Display pin 3
00015     Pin 18 = column 3 Display pin 10
00016     Pin 19 = column 4 Display pin 7
00017     Pin 20 = column 5 Display pin 8 (right-most column)
00018 
00019     Pin 21 = row 1 Display pin 12 (top-most row)
00020     Pin 22 = row 2 Display pin 11
00021     Pin 23 = row 3 Display pin 2
00022     Pin 24 = row 4 Display pin 9
00023     Pin 25 = row 5 Display pin 4
00024     Pin 26 = row 6 Display pin 5
00025     Pin 27 = row 7 Display pin 6
00026 
00027     The code causes the message to scroll across the display.
