i am using a 595 Shift register to display seven segments.
everything is good as i am using common cathode segment with 220ohm resistor on every led.
but its making problems like now its keep G of the Led always on, Sometimes it on some other unexpected LED on during counting
i am providing VCC from arduino 5v but i also use external 5v supply to it,it keeps making problem also then.
Is 220ohm is good enough ?
is it something to do with common anode or common cathode ?
What can be the problem ?
Really sorry for my bad english.
I hope anyone here can help me regarding my issue My advance Thanks to you guys
