Redstone help

[MenltonGomes]

I'm trying to create a redstone door that opens if you throw an item, that is picked up by a minecart hopper, that transmits a signal to open the door. The issue is the only way I found to open up the doors from underneath was using redstone torches, so I stacks 2 on top of each other so the top ones are off, and the bottoms ones are on. I need a way to change the bottom torches off breifly, so the top torches can turn on and activate the door. I can't find any way to do that though, I've tried redstone blocks, observers, comparaters (randomly placed down, I have no idea how they work), and throwing potatoes at it.vidmate mobdro word counter
