No, a shift register chip such as 74HC595.
Then you commit far fewer I/O lines, just 3, from the arduino to run the 14 anodes.
latchpin
datapin
clock pin
using some software like this:
digitalWrite (latchpin, LOW);
shiftout (datapin, clockpin, MSBFIRST, left_data_to_display);
shiftout (datapin, clockpin, MSBFIRST, right_data_to_display);
digitalWrite (latchpin, HIGH);
assuming you had 2 digits, you replace left_data_to_display with your array reference or something, and you put the serail data into the shift register for the right display and let it shift thru into the shift register for the left dislpay.
