    hej :) I am working on some project. I have to make some circuit. The circuit would turn LED on/off, it would invert the state of the LED (0->1 or 1->0). The problem is that I have to use NC pushbutton switch.

    I have made a circuit.. It works but not as well as I want

    How could I achieve this effect?

    thanks
    cheers

    Have you considered using transistors and opamps for your application?

    What is the circuit expected to do?

    I guess the push button is the white square in the diagram, isn't it?

    No I have not considered it because I want to make it from gates. I am sure its very simple.

    Well yeah..
    The white square is the button. If the LED is on the switch turns it off and if it is off it turns it on.

    See if you can figure out how to adapt it to a NC switch.
