Hello,
Is there a general purpose shift register that you would recommend to have on hand for multiple purposes.
I want to:
control multiple LED's with few pins
read multiple switches/buttons with few pins
I believe a shift register is what I need (or multiplexer). Is there a "standard" one I should buy a few of (sorta like how the 555 timer is a standard part to have a few of for various purposes).
Thanks.
