How can you build a circuit in Minecraft in which a signal is only triggered when 2 other signals reach it?

I want to build a circuit in Minecraft. In this slurry you have to press 2 buttons, then a permanent signal from both buttons should come (I have already done this). Now another signal should be given so that the door opens. However, this should only open when both buttons have been pressed.

So 2 signals should trigger 1 additional signal.

If only 1 button is pressed, nothing should happen.

Can someone help me there?

An AND gate

You want to have a logic gate.

More specifically, what you are looking for is an AND gate. If switch 1 AND switch 2 are actuated, the result 1 is otherwise 0.

Ah thanks, but how do you manage that this is only a temporary signal, so it goes out after 3-4 seconds

If you use buttons instead of lever, the signal is only active as long as the buttons are active.

Then both signals would be too short to open the door

That is why I have already ' converted '' the buttons into levers using a circuit.

Only then do I need a mechanism whereby everything resets

The two buttons → AND gate → FlipFlop

You have the short signal between the AND gate and the flip-flop, then you have the continuous signal behind the flip-flop.

What you still need would be something that the flip-flop can reset.
