I was going through multiple tutorials on how to create an Arduino clock with 7 segment displays. I planned to build one and purchased 4 large (4 inches) 7 segment 1 digit displays. The displays run on 12v. And moreover, I got Common Anone displays.
Could you please guide how I can power up 12v Common Anode 7 segment displays by multiplexing? I can write the code part of it and the clock logic. I need help to design the circuit part to drive the 12v Common Anode LEDs with Arduino.
Any help is highly appreciated. Thanks.
Edit: I precisely needed a circuit. A circuit which would be able to power up 4 pieces of 4 inch 7 segment LED display, and with the help of multiplexing I will employ my arduino to lit it up to display desired numbers. So definitely the circuit should consists of an Arduino Unit (Nano, Uno or anything bigger) and 4 numbers of 7 segment digit display. Hope this shortens the scope of the answer.
