is it possible to run 2 seven segment displays to count a two digit number that needs 14 inputs be run from an arduino uno with 13 pins. if so a code sketch would be very helpful
Use a shift register (serial to parallel converter) that takes 3 pins on the Arduino (data, clock and latch) and can drive all the digits you need.
Search in the LED and Multiplexer forum for many, many discussions on this topic. If you really get stuck look for 74HC565 or 74LS565 ic circuits
