    hi all,
    i am obviously a bit of a beginner - although i do know some things - components, basic circuit theory etc.. but what i am looking for is a basic RC timer circuit where it functions like this - you turn a switch 'on' and some amount of seconds later an led comes 'on'. - thats it! but does such a simple rc circuit configuration exist?

    thanks

    Welcome to EP!
    How many seconds delay?
    Does the time need to be adjustable?
    How accurate does the delay need to be?
    How much current does the LED draw?
