  7segment
 
 Counts from 0 to 9 on a 7 segent display, leaving each number lit for a second.
 
 The circuit:
 Connect display as follows, assuming that your display uses the same a-g lettering scheme. 
 Note that I missed out output 3, you are free to repeat this mistake if you like, otherwise adjust accordingly:
 
 a - 1
 b - 2
 c - 4
 d - 5
 e - 6
 f - 7
 g - 8
 common anode - +5V
