Smackflad it is time to stop what you are doing before you get hurt.
You do not seem to understand enough about the Arduinos, Electronics or about High Voltage.
I understand that you have some knowledge but i believe this is enough to get you hurt.There are better ways to approach this!
First i think you should look at some of the tutorials as a lot of what you want to do is covered in them.
I have worked in the electronic industry for over 30 years and have been around 240 volts for most of that so please listen.
You can set up the same circuit that you have in your house, switch, wires and globe using low voltage (under 50 volts) and then set up the Arduino to play around and get what you want but i think that trying to learn about Arduinos, Electronics and High Voltage is just asking to much.
Start off small and work your way up.
Learn about transformers, voltage dividers, AC and DC Power and a whole lot more.I think you are having trouble making your self understood and understanding and this will lead to mistakes you cant afford to make.
You could be hurt, killed or burn the house down.
Make a low voltage model first and experiment.
That is all I can offer you.
Good luck to you.Daz.
Daz thank you for your advice and concern.
I know that I might die because of this but I'm not trying to do it by myself. I have 2 stages. Make it with an small led and then transfer it to the lamps. The second stage I'm doing it with help NOT by my self. The other ways aren't working for me. It is not the first time that I open a high voltage circuit.
