Below you will find a circuit diagram for connecting this unit to an Arduino. Please be aware that the LED segments of this display require a current-limiting resistor when powered from a 5 V logic pin. The value of the resistor is typically between 330 and 560 ohms; the higher the value, the more the current that is limited, and the less bright the LED segments.
