I use a resistor (220 ohm )for each connection between the board pin and digital tube pins.(No need for resistor on the wires connected to the GROUND pin.)
------------------------------------------
Here is the code:

void setup() {
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
digitalWrite(9, 0); // start with "dot" off
}

void loop() {
