Hi everyone!
I am not the greatest with electronics but I have a project which needs remote on/off swich and I was wondering if anybody could point me in the right direction.
It simply needs to turn on a small current (3v) and turn it off again at a distance of about 3 metres without a light path (ie through a curtain). I am at a total loss as to how to achive this... any ideas?
