Hi all. I'm fairly new to the arduino and electronics. I have gone through all the projects that came with the kit and understand it all. However I am now wanting to drive a 7 segment led using a shift register.
One of the projects that came with the kit was driving 8 LEDs with a shift register which I understood as you drove the positive lead of the led high when you want it on. However with the 7 segment led I have, it has the positive as the common to the device (ie all LEDs) and you need connect the LED segments you want to light up to the negative. how can I do this with the shift register? You don't simply drive the pin low do you?
Or can I not use a shift regIster for this?
