Just for fun...

Hi John. Is pin 11 of U1 supposed to go anywhere, only it's not connected
in
the diagram and the circuit doesn't work.

U1-11 is a spare, so its output is supposed to float.

In which way does it not work?

It doesn't light up at all. I better check the wiring though as with all
those diodes the wiring on the breadboard got a bit fiddly!
