I am using seven segment in my project and i was using common cathode and using npn transistor i was able to switch by making arduino pin HIGH.
But now i want to display the data on seven segment when i make the pin as LOW. I mean i want to select the Segment when i will make it LOW.
i was planning to use PNP transisor but for that i will have to change the seven segment to common Anode.
I want to keep common cathode seven segment and want select when i make it LOW.
