    I wanted to build an "and gate" using diode logic, but do I have to use any specific kind of diode ?
    Also I don't understand how diodes work, do they accept all voltages ?
    And lastly, what resistor value do I need ?

    hi there

    do a google search on and gate using diodes there are lots of ideas out there for many types of gates using discrete components

    again there's many tutorials on how components work
    google search how does a diode work

    no they don't

    what resistor ? .... you need to learn about the other things and see how they work before
    worrying about a full circuit and any other components needed
