    Let me start off first by saying that I know NOTHING about circuits.

    I am trying to create a circuit (powered from a standard electrical socket), that has a timer and a light attached to it. Instead of when I turn the timer the light comes on, I would like the opposite to happen (light turns off). The idea is that when the timer reaches 0 of "off", the attached light will turn on. I am using this type of timer (, and most likely some sort of cheap LED light.

    Any questions let me know, as I am pretty well stumped on how to do this!

    If you could help me with this I would GREATLY appreciate it!

    If you know nothing about circuits are sure you can safely wire mains circuits - your safety while building and testing, and also the safety of those around who may come into contact with it?

    Given that the answer to that question is yes then you could use a relay like this one (would need to be built into a box):

    Then connect like this:

    Welcome to AAC!

    Why not keep it simple and use a timer like this? It plugs into an outlet and has two outlets to plug in whatever you want controlled. It has a countdown function and will switch 15A.

    Hello and thank you for the reply! Yes I will be able to make it a safe connection, I just don't know how to connect the circuit so I get the results I want! I appreciate your reply thank you!!
