Hi, I am new to Arduino world, so apologies if anything sounds absurd. Here is my idea -
I will connect a Light in a 3-way switch fashion. One of the 3 way switches will be replaced by relay controlled by arduino. I am able to do successfully so far. But knowing status of light is a problem. To know the status I have to have a control on the manual switch also, which is where I am struck. After doing some reading I find the following idea which may or may not be possible.
Can I connect the switch to arudino while it is still connected to mains? If so how can I do it.
Any other Ideas also welcome. The only thing is I do not want to replace the manual switch.
Thanks in Advance :)
