I would like to know what is What is the maximum of input/outputs usable with MEGA + Mux shield ?
Indeed, with this mux shield, I can use 48 in/out pins by using only 7 pins of the MEGA. Can I use others shift register on the other MEGA pins ?
Indeed, I'd need around 60 Leds + 60 buttons.
I guess the answer is yes, because I can have others SR chains. But I'm not sure !!
any infos would be appreciate :)
