Topic: Help finding multiplexer

Hey everyone!

I've been looking all over the net, to find the hef4067b multiplexer. It's the only parts I need to start my project. If anyone could tell me where to buy those, would i be pleased smile. Im living in Denmark (in EU)

Thanks
Mathias

Re: Help finding multiplexer

Hi Mathias, sorry about the very slow reply!
Any sixteen-way multiplexer chip should do the trick.
You just connect the 16 input-pins to the washers, and the 1 output-pin to the Arduino's input.
Any 16-way multiplexer will have 4 address line pins, and it doesn't matter which order they are connected, as the Arduino will be going through all of the binary combinations (and hence all 16 of the pins).
Perhaps you could try RS, or Farnell?
