    I want to make an AND logic gate that takes as the two inputs:
    1) Impulsions from a microcontroller
    2) High frequency signal from a NE555

    How do I go about doing it?

    I would like to know in what form the microcontroller gives impulsions to the logic gate (which I plan to make with either 2 transistors or 2 diods; which is better?).

    I would also like to know in what form the NE555 gives its high frequency signal to the logic gate.

    I think that would help me connect these components together.

    What comes after these components is a sort of voltage amplifier (which I plan to make with 1 transistor, 3 resistors and 1 capacitor; is that a good idea?) and after this voltage amplifier is a transformer to isolate the microcontroller from the triac that comes after the transformer.

    Finally, the project is actually to regulate the power given to a heating element and the triac is the component that regulates the power that the heating element receives.

    Thank you in advance for helping me answer these questions.
