How do I drive a common-anode display from an Arduino?
Segments light when their pin is pulled LOW, so connect each segment pin through a current-limiting resistor or a driver IC. When multiplexing, switch each digit's common anode HIGH with a transistor, one digit at a time.
What resistor value should I use for each segment?
The value depends on your supply voltage and the LED current you want. Calculate it from the supply voltage, the LED forward voltage and the desired current, and check the display's datasheet for the exact limits.
