i am having problems building a device to interupt a high voltage
flow
of electricity.
i initialy tried to use an optocoupler, which i hoped would respond
to
an audio current as input - interupting the high voltage flow as the
frequency of the audio current increeses and dwindles.
however the optocoupler did not respond with any variation. it was
simply on/of in responce to a complete cercuit on the input -
regrdless of any current in the input cercuit.
alternatively i am looking at this sound operted switch
http://www.saburchill.com/tech/electronics/elect028.html
but can not understand which components i should buy.
basicaly what i want to do is have sound (as electricity) produce
quantitive variation in light (rather than sound).
many thanks for any help anyone could give.
