Arduino with 74HC595 and 7 segment displays

Theoretically there is no limit, but I've tested only two. One guy told me he put 5 in cascade, but it didn't work. But I guess the reason could be related to a limited ampers that he used.

Hope it will be helpfull to you.

Is there a limit to how many shift registers you can cascade? So far, I'm only seeing up to two at a time.
