Hello,
deos anybody know a noob friendly explainaition how the HEF4094 could be run with arduino. The examples in this page are always very complex. To understand the basic functioning I need something like letting an LED blink or so.
Thanks,

This is a serial in / parallel out shift register. It is more complex than a simple blinking LED so don't expect it to be easy going.
It is just a number of simple 1 bit memory cells all linked. Think of it as a line of people each holding a box, the box can be red or blue (logic state on or off). When the instructor blows his whistle the person at the front of the line drops his box and turns round and takes the box from the person behind. This person then turns round and takes the box from the person behind him and so on all the way down the line. Until the last in the line who takes a box from a small hatch in the wall. So the pattern of red and blue boxes shifts down on person each whistle.
In a shift register the whistle is a pulse on the shift clock. The boxes are logic states on the outputs. The hatch in the wall is the input from the arduino.
Now read again:-
Different chip but same principal.
Ahhh, this seems understandable. I will better try the resistor mentioned in the example. I think that does what I need. 
Thank you!
