    Good night guys,

    I have a project and I have doubts in electronics circuit.

    My idea is as follows.

    I have 2 lamps, one green and one red
    LED lamp 127volts

    I want to put an inductive sensor metal ...


    red lamp is on and passes a metal and the green lamp lights.
    and the red sensor is off .... not this more driven. lights the red lamp ....

    I plan on using 2 relay, is possible?
    someone help me?

    Do you want to build a traditional metal detector? There are many, many available examples of these.

    You may want to use standard LED indicators, which are easily powered by a battery, instead of the one you have that requires mains voltage.
