a spot of banter over on UK_Selfbuild led to the following device for making an LED driver with dimming (for lighting - cupboard, room, whatever - not indicators) :
the trick being to substitute a link to an Idratek QAO module output for the potentiometer that's shown connected to the REF/ADJ pins ... not sure quite how to do that yet (more homework required), but thought I'd mention this because LED dimming is not easy to come by !
