I have recently purchased an Arduino micro and am using it to learn more about electronics and embedded systems. I have a numeric LED display HDSP-H101 with the following circuit diagram, and I am trying to figure out how I can use the digital I/O pins on the Arduino to activate different segments of the display.
If the diodes were oriented the opposite way, it would be a simple matter of connecting the output pins (and a resistive load) to each of the pins and the cathode to ground and then when the pin was set to
HIGH a forward-bias voltage would be applied across the LED and it would light up. However, in this case a reverse-bias voltage would be applied and therefore I am unsure of the best way to selectively light each segment?
