Arduino Multiplexer Question
#1
Does anyone know if I can somehow wire multiple 16-channel multiplexers together to get more than 16 channels? I know I can just hook up the second to the next set of output pins, but would rather not waste the pins...

I'm not an arduino or electronics expert Wink

Thanks!

Yes you can. As many as you want. First multiplexer takes 4 outputs from the arduino. On the first multiplexer hook up 4 more... and so forth...

You can also use I2C multiplexer.. Perhaps easier.

Yes. I already tried on my FCDS prototype, but there is a little correction for Daniel's post. You need 4 digital and 1 analog pins from arduino. For the next multiplexer you should connect the same digital pins and an additional analog pin and the whole process go on.

And of course you can save some pins with I2C multiplexers. 

Mike, how much pins do you need? And analogs or digitals?
