Sample code
// show the digit 1 on a Common Anode 7-segment LED display
int segA = 7;
int segB = 6;
int segC = 4;
int segD = 2;
int segE = 1;
int segF = 9;
int segG = 10;
int segDP = 5;

void setup() {
  pinMode(segA, OUTPUT);
  pinMode(segB, OUTPUT);
  pinMode(segC, OUTPUT);
  pinMode(segD, OUTPUT);
  pinMode(segE, OUTPUT);
  pinMode(segF, OUTPUT);
  pinMode(segG, OUTPUT);
  pinMode(segDP, OUTPUT);

}

void loop() {
  // this is for a Common Anode display where a LOW turns on a segment
  // displays the digit 1
  digitalWrite(segA, HIGH);   // turn off LED
  digitalWrite(segB, LOW);    // turn on LED
  digitalWrite(segC, LOW);
  digitalWrite(segD, HIGH);
  digitalWrite(segE, HIGH);
  digitalWrite(segF, HIGH);
  digitalWrite(segG, HIGH);
  digitalWrite(segDP, HIGH);
}

For a Common Anode display, a LOW signal turns on the LED, and a HIGH signal turns off the LED.
