hello, i need help. i have 7 switch. Each switch must give 3 digital output(3pin output). It is like this:
output
switch 1: 0 0 1
switch 2: 0 1 0
switch 3: 0 1 1
....
..
switch 7: 1 1 1
Let say i push the switch 3, then the output can give 011. only one switch can ON once a time.
i try to look at the demultiplexer. but it is like hard to do that.
So any idea on how to build that???
