Hi All
I'm sure this will be an amazingly simple question for someone to answer, however as a hobbyist in electronics I am looking for some clarification.
I have a 2 pin bi-colour LED (Red/Green) and will be running it from a PP3 battery (9v). I simply want to be able to put the led on the battery one way for one colour and the other way round for the other colour.
