Hello! I am planning on making an led digit in 13 segment character format (see below). As the Arduino Deci has 14-2 (rx & tx) = 12 pins, how is this done? Ideally, I would like to make Pin1 = A, Pin2 = B, etc. but with only 12 pins I'm short one. Thank you for any help.

13 segment character

Or just think of the LEDs as a 3x5 matrix and drive them off 8 I/O lines?
