[sdiy] Re: Other LED's

[Peter Snow]

Hi Steve,

That actually sounds more interesting and useful.  This rainbow thingy I got has just the two leads
so there appears to be no way to control the mixing of the colours.  You just have to live with it
cycling through it's little "program".  I have not seen a data sheet so it may be that I could make
it do other things by feeding it different voltages, but I don't think so.

Right now (Harry's and Magnus' suggestions notwithstanding) I think all it is good for is perhaps as
a novelty pendant! :)

Cheers,

Peter
