Shift Register
Shift registers
are a single byte (8 bits) of memory. You can use them to multiply your inputs and outputs. How? Great tutorials on the arduino site for
shifting out
as well as
shifting in
. Long story short, if you have a parallel in, serial out shift register you can get 8 input using only 3 pins. Vice Versa if you have a serial in, parallel out shift register. The power can be multiplied by
daisy-chaining
a bunch of shift registers together.
