I'm trying to send power to one of 10 wires using as few digital outputs as possible. I think I'm going to have to use a 1-of-10 decoder/demultiplexer and control it with 4 digital outputs on the Arduino. My question is... Does a demultiplexer exist that can switch between 1 of 10 outputs, that i…

1-of-10 decoder/demultiplexer using less than 4 inputs?
