Best way to control on/off state of 900 LED individually?

bobcousins:
It depends on what form factor is required, which the OP does not state.

I need to set on and off state of 900 LEDs which have been positioned in a single line.

OK, cheaper than I thought. £115.98 it is! (£125.97 waterproof).


That's 15 metres long by the way. :smiley:
